Study on the Design of Cantonese Cultural and Creative Products using Analytic Hierarchy Process

In this paper, we have studied the design of Cantonese cultural and creative products. In the design process of the system, we use the Analytic Hierarchy Process to analyze the needs of users and apply the analysis results to the product design practice, so as to design Cantonese cultural and creative products more in line with the needs of tourists.


Introduction
Cantonese Culture, that is, the culture of Cantonese ethnic group of Han nationality, is an important part of Chinese Han civilization and is subordinate to Lingnan Culture [1]. roughout the history, the population began to move southward in the Qin and Han Dynasties, which brought the impact of the advanced culture of the Central Plains to Lingnan area. Since the Han and Tang Dynasties, Guangdong, led by Guangzhou, has always been an important window for China's foreign trade. Cantonese have formed a typical "marine cultural character" [2]. erefore, the main characteristics of Cantonese Culture are open-minded and active, daring to be the first in everything, natural and peaceful attitude, focusing on daily life, open and inclusive, pragmatic, and not exclusive.
Based on the understanding of the core of Cantonese Culture, our project team discussed and studied the design of Cantonese cultural and creative products. Usually, cultural and creative products are designed through emotional experience, but lack of rational guidance. In the product design process, it is better to use appropriate mathematical methods, such as Analytic Hierarchy Process (AHP). In 1977, Saaty [3] firstly proposed AHP with the aim of solving problems which can be modeled by a network or hierarchical structure. AHP can be used to solve the problem of comparison of user demand factors. We use it to calculate the weight of factors to carry out the product design.

Less Outstanding Products and Weak Brand Awareness.
e project team investigated the current market of Cantonese cultural and creative products and found that there were few representative products and brands in the market. In the only products, the visual identity is poor and there is lack of systematic design; most enterprises have weak brand awareness and have not formed an influential brand; the lack of clear representative elements makes consumers confused and aesthetic fatigue in regional identification.

e Application of Graphics Is Hard and the Resonance Is
Weak. At present, most of Cantonese cultural and creative products mainly use local representative graphics. For example, the cultural and creative products of Canton tower directly copy the shape of Canton tower, giving people a sense of mechanically copying. e lack of modern design means to analyze, deconstruct, and restructure the characteristic patterns of Cantonese which cannot reflect the added value of cultural and creative products. At the aesthetic level, the expression of product surface decoration is obsolete, less consideration of the aesthetic needs of today's society, and it is difficult to arouse the resonance of consumers.

Single Product Type and Poor Experience.
e great majority Cantonese cultural and creative products on the market are mainly handicraft ornaments, bookmarks, and trinkets. e handicraft thinking of these products is more than the industrial design thinking, and the general practicability is not strong. Nowadays, many Cantonese cultural and creative products still use the product carrier of the traditional handicraft era and do not develop new functions based on the needs of consumers' life. In addition, in the product reflection level, the cultural depth is not fully explored and the communication is not precise enough. Cultural and creative products need more in-depth consideration from the functional level, aesthetic level, and philosophical level to arouse the psychological resonance of consumers.

Cantonese Cultural and Creative Product
Audience Demands e consumption groups of Cantonese cultural and creative products are mainly local people and tourists in Guangzhou. According to the data, Guangzhou received 16.2383 million tourists during the National Day golden week in 2019, accounting for about one third of the total number of tourists in the province. Guangzhou is located in the Pearl River Delta, adjacent to Hong Kong and Macao, so the inbound tourists in Guangzhou are mainly composed of foreigners, Hong Kong, Macao, and Taiwan compatriots. Among them, Hong Kong and Macao tourists account for about 60% of the total flow, while Asian tourists account for 30% of the total flow, followed by European and American visitors. Due to the fact that Guangzhou has two sessions of Canton Fair every year, and the geographical advantage of being adjacent to Hong Kong and Macao, the inbound tourists in Guangzhou have their unique characteristics in tourism destination structure. With the heating up of tourism industry, it brings huge business opportunities. However, the low sales revenue of tourist souvenirs in Guangzhou is in contrast with the rapid development of tourism. Cantonese cultural and creative products can be used not only be as tourist souvenirs but also as the name card of the city. Nowadays, the business card of Guangzhou is vague and not good enough to be used.
Western psychological scholars have put forward some different theories of human motivation, which have certain reference value for audience analysis and marketing strategies. Among them, the most popular one is Maslow's "hierarchy of needs" theory [4]. According to the demand hierarchy theory and the market survey completed by the project team in the early stage, we can sort out the audience demand of Cantonese cultural and creative products, so as to enhance the rationality and effectiveness of the later product design practice.

Appearance Requirements.
e lowest level of Maslow's demand level is the basis of the transition to other levels. e external demand for products belongs to the most direct and instinctive response of human beings. It emphasizes the physiological characteristics of users' gaze, feeling, and voice. In the early stage, the project team took frequent visitors to Guangzhou as the main target group, sent out 117 questionnaires, and recovered 117 valid questionnaires. In the preliminary research, among "factors affecting the purchase of Guangzhou souvenirs," 36.84% of the respondents chose "appearance, commemorative significance, and usability," which is a very good illustration that tourists consider whether the products meet the basic demand as the most basic factor to influence the purchase.

Functional Requirements.
Functional requirements are in the middle of Maslow's hierarchy of requirements. e function demand is related to the utility of the product, which emphasizes whether the product can solve the problems in life smoothly for users. Pragmatism is an important feature of western culture. Cultural and creative products with practical functions have the basis of commercial value, and they are also the first choice for tourists in Guangdong Province who combine Chinese and Western culture. In the preliminary investigate and survey, among the question "which features of cultural and creative products do you pay more attention to?" 38.46% of the respondents chose "practicability," accounting for the first place, which proves that consumers are attached great importance by the functional characteristics of Cantonese cultural and creative products.

Cultural Needs.
Cultural needs correspond to Maslow's level of self-demand, and in the pyramid, it refers to a kind of ideological and spiritual transition after functional needs are met. e goal of product design is not only to enable users to use the product but also to meet their deep emotional needs in the multilevel interaction with products in the modern market environment with serious homogenization of functions. In the questionnaire, 74% of the respondents chose "custom" and 63% chose "traditional art" for "which cultural elements do you prefer to buy Guangzhou souvenirs?" Due to the unique composition of Guangzhou tourists, Hong Kong, Macao, and Taiwan compatriots, Asian and Western tourists account for a large proportion. eir aesthetic taste is more influenced by the West and has its uniqueness.

Hierarchical Analysis of User Requirements 4.1. Analytic Hierarchy Process. One comprehensively utilized Multicriteria Decision-Making (MCDM) strategy is AHP [3,5,6]. Analytic hierarchy process decomposes the decision-making elements into objectives, criteria, schemes, and other levels, on which qualitative and quantitative analysis are carried out. It is a simple, flexible, and practical multicriteria decision-making method for quantitative analysis of qualitative problems. AHP is utilized to measure, order, rank, evaluate decision choices, etc. AHP estimates criteria weights by pairwise comparisons. is method is helpful to determine the relative weight which should have each criterion when we need to make a decision. erefore, it has been applied in various fields such as environmental management [7], risk assessment [8], and supply chain management [9]. AHP has three advantages: systematization, which regards the object as a whole system and makes decisions according to the thinking steps of decomposition, comparison, judgment, and synthesis; practicability, combining qualitative, and quantitative methods, can deal with problems that cannot be solved by traditional optimization methods; simplicity, it is easy to calculate and clear in results so that decision makers can quickly and directly understand and master. Now, we give the main steps of the AHP.
Step 1: define the central questions, choices, and judgment criteria Step 2: using the fundamental scale of Table 1 to create the pairwise comparison matrix Step 3: determine the criterion weight vector. Normalize the comparison matrix by equation (1); then, calculate the average of each row of the normalized comparison matrix by equation (2) to obtain the weight vector: a ij n , i � 1, 2, . . . , n. (2) Step 4: using equations (3) and (4) to compute the consistency index (CI) of the comparison matrix: Step 5: calculate the consistency ratio (CR) by equation (5), where the random consistency index (RI) value is determined by Table 2: Step 6: compare the obtained CR with the value considered acceptable for consistency.

Application of AHP to the Design of Cantonese Cultural and Creative Products.
e analytic hierarchy process model is established. First of all, the questionnaire is distributed to the tourists who often travel to and from Guangzhou. en, it takes the user demand factors of Cantonese cultural and creative products as the goal level, takes the appearance factors, function factors, and culture factors corresponding to Maslow's demand level as the criterion layer, and extracts nine perceptual words from the user demand vocabulary of typical user interviews as the criterion layer, so as to guide the design of product appearance, function, and culture. Figure 1 shows the analytic hierarchy process model of user demand factors of Cantonese cultural and creative products. e test group is composed of 117 effective users mentioned above. According to the index system, questionnaire survey is conducted by focus group combined with information method in user survey and decision is made. e importance of the goal layer, criteria layer, and evaluation index layer are scored, respectively. en, the scoring results are discussed and summarized internally, and the pairwise judgment matrixes (see Tables 3-6) are obtained, and reasonable conclusions are drawn through consistency test. e judgment matrix is constructed and related calculation is carried out, and the relevant data are presented as follows.
e criteria layer judgment matrix is denoted by then by equation (1), we can get the following normalize the comparison matrix: By equation (2), we get the criterion weight vector:         (4), we obtain λ max � 3.0096.
Since the order of A is 3, by equation (3) we obtain Because n � 3, we know that RI � 0.58 from Table 2, then by equation (5), we obtain CR � 0.0083.
Similar with the above procedure, we obtain the results as follows and do not show computational process in detail for simplicity.
rough the analytic hierarchy process, the consistency ratio of each factor layer judgment matrix evaluation index is less than 0.1, which indicates that the test team has passed the consistency test on the user demand hierarchy factors. e order of the importance of the decision-making level is as follows: culture factors > function factors > appearance factors, which shows that culture factors are more important for the design of Cantonese cultural and creative products.
In the order of the importance of functional factors in the evaluation index layer, the order of importance of culture factors is Cantonese customs > auspicious meaning > inclusive attitude > adventure spirit, which shows that Cantonese customs are the most important in culture factors. e order of importance of function factors is durability > portability > decorative, indicating that durability is the most important factor. e order of importance of appearance factors is as follows: beauty > brand > individuality, which indicates that the beauty of products is more important in appearance factors.

Appearance Design.
Cantonese architecture mainly refers to the traditional architecture in Cantonese area, which refers to the building with traditional style built by using traditional building technology and building materials. Cantonese architecture is closely related to Cantonese culture and style and has strong regional characteristics. e cultural and creative design chooses the "Bahe guild hall" which is very historic and representative in Guangzhou Xiguan as the main design element. "Bahe guild hall" is the guild organization of Cantonese opera artists, formerly known as "Qionghua guild hall" [10]. is guild hall strengthened the unity of people in the opera industry, ensured the normal operation of the troupe, and resumed the troupe business after the lifting of the ban on Cantonese Opera in the Qing Dynasty. "Bahe" have branches all over the world, where there are Chinese, as long as there are Cantonese opera, and there are these guild halls. e long history and profound cultural heritage of Guangzhou's "Bahe," which are respected as their ancestors all over the world, are of great significance. ey not only enable the intangible cultural heritage art of Cantonese opera to continue to be inherited but also represent the profound Cantonese opera culture and the indomitable spirit of Cantonese people.

Function Design.
In the early research, we learned that tourists are more interested in some small products and stationery products, so we chose the four treasures of the study as the design objects, including a pen holder, a pen shelf, a paper weight, and an ink slab (see . In the functional design, people pay more attention to the durability of the product, so in the design of the whole set of products, we strive to achieve a stable and reasonable structure.

Culture Design.
e top half of the pen holder refers to the iconic roof of "Bahe guild hall," while the lower part is added with window decoration elements; the shape of pen shelf is transformed from the roof shape of "Bahe guild hall," which is round and beautiful as a whole; the paper weight is decorated with the exterior wall patterns of the guild hall; the ink slab is designed by combining the cloud pattern on the ceiling of the guild hall with the architectural elements.

Conclusions
In the research of social science [11] and natural science [12][13][14][15][16][17][18], the selection of methods is very important. In this paper, we choose to use an effective method, AHP, to study the design of Cantonese cultural and creative products. Based on the AHP model of user demand, we sort out the user needs of Cantonese cultural and creative products, conduct trade-off screening on the design demand factors of these products, so as to further quantify the needs of tourist groups, determine the most suitable combination of product design factors for users, and apply the conclusions to the design practice. With the vision of tourists, we can design products to meet the needs of tourists so that the cultural and creative products of Cantonese will be loved by more people, and the culture of Cantonese will spread faster and farther.
