Optimization of Cross-Border e-Commerce Logistics Supervision System Based on Internet of Things Technology

,


Introduction
In recent years, the application of cross-border e-commerce is more and more widespread, and cross-border electronic logistics is also closely followed. One of the most important advantages of cross-border e-commerce is that it is able to break through the national boundaries of the traditional commerce; e-commerce may conduct business transactions between different countries, change the traditional offline trading patterns into online, and make the process more convenient and quick, combining the way of traditional logistics and e-commerce [1]. Cross-border e-commerce makes the circulation of goods at home and abroad much smoother, breaking the traditional commodity trading time and regional restrictions, but there are still some problems in the process of commodity transportation, because the national customs are very strict on the inspection of crossborder goods. erefore, the cross-border electronic logistics will face very strict customs screening and will also face different problems raised by the customs agencies of various countries. But in recent years, the cross-border e-commerce industry in China has been making continuous progress, which has also led to the development of the national economy to a large extent. erefore, the country has launched a variety of supporting policies, which undoubtedly makes the development of cross-border e-commerce quite faster. e development of cross-border e-commerce needs the support of fast and safe logistics delivery and requires a higher level of logistics service to improve competitiveness.
e main logistics problems faced by small-and mediumsized enterprises in the development of cross-border e-commerce in Quanzhou mainly include the following aspects: the high logistics cost, weakening the price advantage of cross-border e-commerce products; the long logistics links affecting the timeliness of cross-border e-commerce; the complex logistics process increasing the risk of cross-border e-commerce; the low level of logistics informatization affecting the customer experience of crossborder e-commerce; the shortage of cross-border logistics talents affecting the rapid development of cross-border e-commerce [2]. erefore, this paper aims to analyze the development status of cross-border e-commerce and the application of Internet of ings technology, find out the logistics problems faced by enterprises in the development of cross-border e-commerce, and try to find out the countermeasures to solve these problems. It is hoped that this study can provide theoretical reference for relevant research and provide reference for the rationalization of cross-border e-commerce logistics. e rest of this article is organized as follows: Section 2 discusses the relevant work. Section 3 elaborates the crossborder e-commerce logistics supervision system based on Internet of ings technology. Section 4 presents functional optimization and testing of cross-border e-commerce logistics supervision system. Section 5 summarizes the text. Under the framework of the monitoring system, this paper realizes the functions of group intelligent contract, legal anonymous identity authentication, intelligent transaction matching, abnormal data analysis and detection, privacy protection, and traceability. en the security, controllability, and operating efficiency of the framework are verified by security analysis and transaction monitoring software.
e measurement results show that the proposed crossborder logistics supervision system is secure and controllable and can protect the privacy of e-commerce logistics users and data, prevent forgery and fraud, and achieve the auditability and traceability of user behavior and user data.

Related Work
e development of cross-border e-commerce cannot be separated from the support of cross-border logistics. Only when the two develop together can they achieve a win-win situation. According to the collation and analysis of the published literature, it is found that experts and scholars mainly conduct research from two aspects in the research process: Ma et al. [3] analyzed the commonly used logistics modes and characteristics of cross-border e-commerce in China. Li et al. [4] analyzed the diversified demands of crossborder e-commerce and its development status in China and proposed a logistics and transportation mode suitable for cross-border e-commerce. Xie et al. [5] chose India as the research object, discussed the mode adopted in the development of cross-border e-commerce, analyzed the problems and countermeasures in the development of cross-border e-commerce, and laid a foundation for the development of cross-border e-commerce logistics mode in other countries. Taking China as the research object, Zhang et al. [6] discussed in detail the e-commerce development mode that can be adopted by small foreign trade agency enterprises in the development process and analyzed the development status and existing problems of their cross-border e-commerce. At the same time, the countermeasures that can be taken in the process of its development are given. It is concluded that foreign experts and scholars pay great attention to the analysis of the development model of e-commerce in the research process and analyze the existing problems and countermeasures in the use of the existing model. ese analyses provide reference for the development of cross-border e-commerce model of freight forwarders in China. Secondly, as for the research on the development strategy of crossborder e-commerce logistics, Sun et al. [7] analyzed the crossborder logistics mode that can be adopted in China's tea and clothing industries. Porambage et al. [8] proposed that crossborder e-commerce enterprises should form a good cooperative relationship with cross-border logistics enterprises, so as to ensure the logistics and transportation quality of crossborder e-commerce commodities under the B2C mode, reduce logistics and transportation costs, and improve logistics and transportation efficiency. Mohammed et al. [9] analyzed the commodity transport channels adopted by cross-border logistics enterprises and used empirical methods to verify the application of e-commerce platforms in the development process of cross-border e-commerce. Cao et al. [10] analyzed win-win cooperation approaches between cross-border e-commerce enterprises and logistics enterprises and pointed out that the Internet is the key to maintain their relationship. It can be concluded that when foreign experts study crossborder e-commerce logistics, they make targeted analysis on its existing problems and put forward specific solutions. ese solutions can provide reference for the sustainability of crossborder e-commerce business development of Chinese freight forwarding enterprises.
ere are also a large number of researches on crossborder e-commerce logistics supervision based on the Internet of ings technology in the literature. rough sorting and analysis, the research are mainly carried out from the following three aspects: Firstly, on the research of cross-border e-commerce and international logistics supervision mode, Xiao et al. [11] take the third-party logistics as the research object, analyze the development mode adopted in the context of cross-border e-commerce and the problems existing in the existing mode, and then put forward the countermeasures that can be taken. Mou et al. [12] chose Company T as the research object to analyze the logistics regulatory operation mode under the background of cross-border e-commerce and discussed from the aspects of its monitoring system, logistics service, operation technology, and transportation economy. Ai et al. [13] chose foreign trade enterprises as the research object to analyze their logistics and transportation supervision mode under the background of cross-border e-commerce. Secondly, regarding the research on the current situation of crossborder e-commerce logistics and the problems faced in supervision, Zhang et al. [14] take cross-border logistics enterprises as the research object, analyze the business models they can adopt and the regulatory problems they face in the process of economic globalization development, and then put forward corresponding solutions, so as to provide better logistics and transportation services for the development of cross-border e-commerce. Li [15] selected China's Heilongjiang province as the research object to analyze the problems in its cross-border commodity transportation process and the supervision scheme, that is, to further optimize the cross-border commodity logistics 2 Complexity and transportation process through the introduction of information technology and personnel training. irdly, on the research of cross-border e-commerce logistics supervision strategies, Li et al. [16] proposed the necessity and advantages of the development of third-party logistics through the analysis of the current development of crossborder e-commerce in China and proposed specific supervision strategies. Sun et al. [17] also chose the third-party logistics as an example to discuss the relevant situation of its development under the background of cross-border e-commerce and analyzed its development problems from internal and external aspects. Finally, combined with the specific situation of the development of the third-party logistics of cross-border e-commerce in China, the optimization strategies that can be adopted are proposed.

Construction of Basic Platform.
To achieve effective electronic logistics supervision, it is necessary to consider the construction of a reasonable cross-border e-commerce and logistics collaborative platform. ere is a mutual promotion and inseparable relationship between cross-border e-commerce and logistics. e development of cross-border e-commerce cannot be separated from the support and guarantee of logistics, and the development of logistics also needs the strong promotion of cross-border e-commerce. Although cross-border e-commerce and logistics belong to two different industries, they are actually a whole and closely linked to each other. e coordinated development of the two has an important impact and significance on the economic growth and development of a region and even a country. According to the composite system theory, crossborder e-commerce and logistics belong to two systems, but they are contained in a large composite system, and belong to two subsystems. e two subsystems are affected by a variety of factors, which can affect the structure, behavior, and function of the system and can be called order parameters. e size of these factors reflects the operating state and order degree of the subsystem in different stages. Based on the construction and research of the synergistic degree model, this paper constructs the synergistic development model of cross-border e-commerce and logistics.

Construction of Subsystem Order Degree Model.
Suppose that the composite system of cross-border e-commerce and logistics is S i , where i � 1, 2, that is, S i � {S 1 , S 2 }, S 1 and S 2 , respectively, represent the subsystem of crossborder e-commerce and logistics in the composite system. e order parameters in the subsystem development process can be used e i � (e i1 , e i2 , . . ., e ij ), where j � 1,2,3, . . ., n, α ij ≤ e ij ≤ β ij , α ij and β ij are, respectively, the upper and lower limits of the order parameter index data of the critical point of system stability [18]. en the value range of the order parameter of the cross-border e-commerce subsystem is α 1j ≤ e 1j ≤ β 1j , and the value range of the order parameter of the logistics subsystem is α 2j ≤ e 2j ≤ β 2j . e order parameter is the degree of system ordering and the measure of the collaborative development of subsystems. Its size represents the degree of macroorder. When the order parameter is zero, the system is disordered [19]. When E i1 , E i2 , . . ., E ij represents the benefit index, the larger the value is, the higher the degree of order is; the smaller the value is, the lower the degree of order is. When E i1 , E i2 , . . ., E ij represents the cost index, the larger the value is, the lower the degree of order is; and the smaller the value is, the higher the degree of order is. erefore, the order degree of order parameter component index e ij of the subsystem can be defined by its efficiency function, that is, the contribution degree of each order parameter index in the subsystem, as shown in Starting from the whole composite system, the overall coordination and development of the system is not only determined by the contribution of order parameter components in the subsystem, but also determined by the integration and integration among order parameters. erefore, the calculation of subsystem order degree can be realized by the integration of the function μ (e ij ) of order parameter e i [20]. erefore, the order degree of the statutory subsystem can be calculated by linear weighting, as shown in where u i (e i ) in the formula represents the subsystem order degree, and 0 ≤ u i (e i ) ≤ 1. e larger the value is, the greater the contribution will be and the higher the subsystem order degree will be. w j is the weight coefficient of each order parameter component index, namely, the relative weight of each order parameter, and refers to the role of each order parameter in the ordered development process of the subsystem.

Establishment of the System Synergy Degree
Model. e development of cross-border e-commerce and logistics is a process of dynamic evolution, and the relationship and function between various subsystems are not invariable [21][22][23]. erefore, the degree of order and synergistic effect in different periods should be dynamically measured with the development [24,25]. Assume that the order degree of subsystem Si of the composite system of cross-border e-commerce and logistics is u t0 i (e i ) at the initial stage of t 0 and u t1 i (e i ) at the moment of T1 in the development and evolution process and then in the process of development from t 0 to t 1 . e synergistic degree of the composite system composed of two subsystems, cross-border e-commerce and logistics, is U, and the calculation of U is shown in the following formula: It can be seen from the formula that the degree of synergy between cross-border e-commerce and logistics system is obtained by the change of the order degree of subsystems, and the value range of its degree of synergy U is [−1, 1]. e closer it is to 1, the higher the degree of synergy between cross-border e-commerce and logistics will be, and the closer it is to −1, the lower the degree of synergy of the system will be. e synergy model constructed above fully analyzes the orderly development of the two subsystems and provides a systematic basis for the establishment of an effective and feasible supervision system.

Structure of Cross-Border E-Commerce Logistics Network.
Based on the characteristics of cross-border e-commerce, the structure of cross-border logistics network is divided into three stages: logistics of the exporting country, international logistics, and logistics of the importing country. e nodes are the sellers of cross-border e-commerce, the transit warehouse of the exporting country, the transit point of international logistics, the bonded warehouse of the importing country, and consumers, respectively [8,26,27]. e connection between the nodes is the line connection between the nodes. e five types of nodes in the cross-border e-commerce logistics network are (1) cross-border e-commerce sellers, including traditional enterprises, e-commerce enterprises, and individual merchants; (2) transit warehouse of the exporting country, where the exported commodities are gathered through the domestic logistics link to complete the process of commodity inspection and customs declaration; (3) international logistics transit points, including ports and airports, corresponding to water and air transport modes, respectively; (4) the bonded warehouse of the importing country, where the customs declaration and commodity inspection are completed, and some merchants keep their goods in the bonded warehouse of the customs, which is equivalent to the distribution center; (5) consumers. After the last kilometer of distribution, the goods finally reach the consumers, and the whole cross-border e-commerce logistics process is completed. e physical network topological structure formed by these nodes and the connections between nodes and the goods flow on the connections between nodes constitute the cross-border e-commerce logistics network system.
Cross-border e-commerce logistics network is composed of nodes and edges with different natures. To build a crossborder e-commerce logistics network model, these nodes and edges need to be abstracts into homogeneous nodes and edges of the network. e logistics network model of crossborder e-commerce is described as In the formula, G is the entire cross-border e-commerce logistics network; V is the node set of cross-border e-commerce logistics network, including cross-border e-commerce sellers, transit warehouse of exporting country, transit point of international logistics, bonded warehouse of importing country, consumers, and other practical nodes. If V � n, it means that there are n nodes in the network, V � {v 1 ,v 2 ,v 3 ,. . ., v n }. E is the side of cross-border e-commerce logistics network, including urban roads, sea routes, air routes, and highways. D is the set of section distance, D � d ij |i, j ∈ n , is the set of load flow, and is also the set of edge weight. In this way, the cross-border e-commerce logistics network is transformed into a weighted undirected connected graph including cross-border e-commerce sellers, transit warehouses of exporting countries, international logistics transit points, bonded warehouses of importing countries, consumers, and logistics roads, as shown in Figure 1.
Cross-border e-commerce logistics network is distributed in the global scope, which has the characteristics of small batch, multifrequency, long distance, and being easy to be affected by spatial geographical conditions. At the same time, cross-border logistics passes through many intermediate nodes and has a long logistics cycle. In the cross-border e-commerce logistics network, nodes mainly realize different functions such as warehousing, packaging, and customs declaration. From the perspective of network structure, the degree of different nodes is very different, which has the characteristics of nonuniform distribution.
In the process of cross-border e-commerce logistics, there are five types of nodes, including cross-border e-commerce seller, transit warehouse of exporting country, transit point of international logistics, bonded warehouse of importing country, and consumer. When constructing network model with complex network theory, the nodes are abstracted into homogeneous network nodes without considering the heterogeneity of nodes. erefore, this section takes the differences of nodes into consideration and divides the nodes of cross-border e-commerce logistics network into the following three categories: Class I nodes: terminal nodes, including nodes of cross-border e-commerce sellers and consumers. In comparison, the business volume of such nodes is small and the degree of such nodes is small. e second is Class II node: midtransition logistics node, including transit node in the international transportation process such as transit port, airport, and railway station, as well as transit warehouse node in the exporting country, which realizes logistics transit activities such as functional storage, cargo collection, and distribution.
is class of nodes is of medium degree. e third is Class III node: middle transition function node. is kind of node refers to the customs and realizes the national inspection and commodity inspection of goods. When the goods need to be stored in the bonded warehouse, this kind of node also realizes the storage function. is class of nodes has the greatest degree. Connected nodes, the main 4 Complexity function of transport cross-border electricity logistics network nodes between single transport cargo is small, but the current frequency of relatively more, and the frequency of different logistics process between different nodes, this leads to cross-border electricity logistics network, the edge load capacity is also different, this will be represented by the edge of the weight. At the same time, the weight of the node will also be expressed by the weight of the edge. e cross-border e-commerce logistics network is similar to the general logistics network in that the flow of goods is b i -directional, so the directional problem is not considered in the cross-border e-commerce network. To sum up, the cross-border e-commerce logistics network constructed in this paper is the undirected weighted network graph G � V, W, R { }, as shown in Figure 2, which represents the nodes in the network, represents the risk grade coefficient on the edge, and represents the weight of the edge in the network. Adjacency matrix is established according to network graph G, as detailed below: where a ij and b ij , respectively, represent the values of the adjacency matrix in the horizontal and vertical directions, where i � 1,2,3, . . ., n; j � 1, 2, 3, . . ., n.

Construction of Cross-Border E-Commerce Logistics Supervision System.
is paper focuses on the theoretical framework of cross-border logistics monitoring and supervision and gives the corresponding implementation methods. e hierarchical and multilayer intelligent logistics regulatory framework is shown in Figure 3.
Each node on the chain usually has a corresponding industry, such as logistics and financial entities. Participants join the network through authorization and form a stakeholder alliance, which maintains the operation of the block chain. erefore, as a general solution, this framework is applicable not only to the field of crowd sourced logistics, but also to other industrial areas such as inclusive finance. e whole transaction regulatory framework deploys two levels of regulatory points. Among them, the supervisory point I is the top-level national authorized certification center of the supervisory structure, which is the trust root of the intelligent service transaction regulatory framework to deploy and implement the supervision module of enterprise implantation to the alliance chain of the registration marrow. All industries or organizations to the national authorized certification center to apply for the deployment of the implementation of the alliance chain need to provide the access proof including enterprise legal person, qualification certificate, and other entity information and sign the monitoring implant informed agreement section. Monitoring and implantation of informed agreement are a legal effect of the alliance chain implementer to accept the supervision of the superior competent department of the National Authorized Certification Center. It shows that all the transaction data and operation logs are authorized by the National Authorized Certification Center real-time access.

Logistics Supervision Methods Used by the System.
is section takes the modern logistics service industry as an example to introduce the transaction supervision method supported by the hierarchical and multilayer intelligent logistics service regulatory framework. As shown in Figure 4, where 19 tags have been added, the implementation of the whole approach involves two aspects: (1) Supervision of logistics service platforms by the National Certification and Authorization Center: the intelligent service platform first needs to submit the qualification to the national authorized certification   6 Complexity center (AC). e National Authorized Certification Center shall conduct a comprehensive assessment on whether the logistics service platform has the qualifications after necessary identity, qualification, and reputation retrieval. If it has the service access qualification, it will be issued with the corresponding authorization license (license) to make it become a legal intelligent transaction service node. Strapped home authorization certification center to the logistics service platform issued the authorization license and the service platform industry alliance chain implants the corresponding functional level of regulatory functions. e logistics service process refers to the use of chain plug-ins embedded in the logistics service platform and industry alliance supervision functions by the national authorized certification center for data collection and online analysis. It captures the abnormal behavior in the process of the trade service platform in real time, such as the data on the behavior of prohibited items on the national chain.
(2) e logistics service platform has great influence on the main participants of logistics: logistic service requesters (Requester) and workers (Workers) register in the logistics service platform, and the service platform checks their identity, reputation, etc. (if necessary, they need to seek help from the National Reputation Center through the National Authorization Center). Requester (specifically and successfully registered) submits a logistics task request to the logistics service platform, and the server triggers a smart contract (running a specific task matching algorithm) to automatically match the logistics request with the Worker and submits the matching result to Miner. e service platform will reward and punish workers according to the completion of logistics tasks.

Implementation of the Regulatory
Framework. e software architecture of the cross-border e-commerce logistics supervision system is shown in Figure 5. e middle part is the intelligent logistics service center. It is divided into the overall architecture design, hierarchical multilayer supervision design, and monitoring node function design. e overall software architecture design includes the following functions and research contents: (1) regulation area division and node deployment, aiming at improving the efficiency, accuracy, and expansibility of regulation; (2) design of regulatory interface for intelligent service trading, that is, different regulatory access modes adopted for different types of energy service trading systems. e functions of supervision node mainly include object identity authentication, transaction record storage, abnormal behavior gun detection, supervision action implementation, supervision log recording, and other functions.
Based on the above functional requirements, the intelligent service trading regulatory framework platform development includes verification of the built intelligent service trading regulatory platform availability and efficiency. At the same time, it verifies the availability and efficiency of the service transaction operation and supervision scheme focused on the supervision platform and the traceability scheme oriented to the multimodal transaction object, and then it comprehensively verifies the stability, real time, and accuracy of the intelligent service transaction supervision platform.

Risk Resistance Testing and
Optimization. Now, it is assumed that there are 2 international logistics transit points, 8 cross-border e-commerce seller and exporter transit warehouses, and 10 cross-border e-commerce bonded warehouses and demand points.
is network is abstracted into an undirected network weighting diagram with 20 nodes and 34 edges by using the representation method of complex network (as shown in Figure 6). e simulation experiment process is as follows: in the random destruction simulation experiment, one node or edge is deleted randomly each time until all edges or nodes are deleted, and the results of 8 experiments are averaged. In the simulation experiment of intentional attack, the importance of nodes or edges is sorted according to the number of nodes or edges, and one node or edge is deleted each time from high to low. When there are multiple nodes or edges with the same number of nodes or edges, it is determined by random selection until all nodes or edges are deleted.
As can be seen from Figure 6, in the case of random destruction, the proportion of nodes deleted in the network reaches about 80%, and the network risk efficiency drops to 0, indicating that the network is in a state of paralysis at this time. However, in the case of deliberate attack, the proportion of nodes deleted in the network is about 60%, and the network is in a state of paralysis. It can also be seen that intentional attacks are more destructive than random ones. All these indicate that the cross-border e-commerce logistics network is vulnerable to deliberate attacks and robust to random destruction, which proves that the cross-border e-commerce logistics network is a scale-free network. e loss caused by random sabotage and deliberate attack to cross-border e-commerce logistics network is almost the same. With the increase of the proportion of edge deletion, the loss caused by deliberate attack to network increases sharply. When the proportion of edge deletion reaches about 80%, the loss caused by deliberate attack and deliberate attack tends to be the same. Again, intentional attacks are more destructive than random ones. Moreover, the stability of the network is maintained by the important edges. In the actual security maintenance of cross-border e-commerce logistics network, special attention should be paid to the protection of important traffic lines. Keeping the lines unblocked can effectively maintain the network structure, thus reducing the occurrence of network losses.

Optimization of Supply Chain Supervision.
In terms of supply chain management, compared with traditional trade, the supply chain of cross-border e-commerce has the characteristics of fewer links in the whole supply chain process and convenient transaction mode. ere are big differences in the way they are regulated. e import and export of cross-border e-commerce mainly include four regulatory modes: "bonded import online," "direct purchase import," "general export," and "export from special regions." As shown in Figure 7, crossborder e-commerce companies generally sell goods directly to consumers through manufacturers or brand owners, and there are only international logistics, overseas warehouse, bonded warehouse, and customs clearance procedures in the middle. In addition to the above process nodes, traditional trade generally involves general distributors, provincial distributors, regional distributors, and retailers. ere are many transaction links and the overall cost of supply chain is high. Domestic consumers in cross-border electric business platform after order, the merchants of platforms, or the electric business platform will be the order of the order information, payment information, and logistics waybill information submitted to the customs special cross-border electricity cross-border import customs clearance formalities declaration system (i.e., cross-border business model declaration), and then the customs are in accordance with the terms of this commodity category such as tax rate and tax department. Import and retail tax shall be levied on the goods in the order, and automatic verification and cancellation shall be carried out on the commodity account book of the customs after the relevant information is verified and released. e general trade mainly includes import and export declaration, inspection, payment of taxes and fees, goods release four supervisory links. For general trade import and export declaration, the first is the enterprise or individual, in accordance with the relevant law within the prescribed time limits, in the import and export port or close condition, the corresponding electronic customs clearance or paper declaration, declare to the customs import and export commodities actual situation, including the information such as quantity, price, countries, and regions, and then the customs to declare documents for review process.
en, it is necessary to cooperate with the customs for inspection. In order to determine whether the corresponding import and export commodities match with the declaration documents, or to determine the geographical and physical attributes of the commodities, the relevant commodities need to be checked. In this way, we can judge whether the enterprises or individuals who declare are cheating or not. At the same time, the customs inspection also provides reliable data support for the reasonable taxation of the customs.

Orderly Degree Test of the Supervision System.
In the two subsystems of cross-border e-commerce and logistics, the influence degree of each order parameter index on the system is different. In order to improve the accuracy and effectiveness of their collaborative supervision system, different weights should be given to each order parameter index. e weighting method mainly includes the subjective weighting method and the objective weighting method, and the objective weighting method has the principal component analysis method, standard deviation method, entropy weight method critic method, etc. [28,29]. e index of order parameters of crossborder e-commerce and logistics in Henan province is calculated by standard deviation formula. In this paper, SPSS18.0 software was used to carry out correlation analysis on the order parameter indexes of the cross-border e-commerce subsystem and logistics subsystem of a city, and the correlation coefficient matrix was obtained. e weights of the order parameter indexes of the cross-border e-commerce subsystem and logistics subsystem of the city were, respectively, calculated. e results are shown in Figure 8.    In addition, the overall synergy degree between crossborder e-commerce and logistics is calculated according to the composite system synergy degree model. e collaborative development trend of cross-border e-commerce and logistics in Henan province plotted by the data results of the order degree of cross-border e-commerce and logistics subsystem and their overall synergy degree is shown in Figure 8.

Conclusion
is paper proposes a regulatory framework for crossborder e-commerce based on the Internet of ings, aiming at the typical industry of crowd sourced logistics in modern service industry. e system adopts a two-level supervision model: the first level is the supervision of the national authorization center on the logistics service platform and the second level is the supervision of the logistics service platform on the logistics participants. en, with the business logic of crowd sourcing logistics as a reference, the implementation method of e-commerce logistics transaction regulatory framework is elaborated in detail, and the closedloop security analysis of the scheme is carried out according to the chronological sequence. e analysis results show that the proposed hierarchical and multilayer cross-border e-commerce logistics regulatory framework is safe and controllable. Finally, the corresponding software design architecture is proposed, which realizes the functions of node analysis, optimization of system network structure, implementation and supervision of logistics service based on Internet of ings, and traceability of multimodal transaction objects. In the case of random destruction, the proportion of nodes deleted in the network reaches about 80%, and the network risk efficiency drops to 0. With the continuous development of e-commerce, cross-border logistics should also keep up with the pace of e Times and constantly improve the logistics and transportation system. Meanwhile, cross-border logistics involves multiple logistics companies, which can exchange experience, communicate, and coordinate with each other continuously, so that goods can reach customers more quickly, and accelerate the development speed of electronic business and optimization.
