The importance of systematical analysis and evaluation methods for energy business ecosystems

In recent years, business ecosystems have gained popularity in many sectors due to the increasing awareness of the value of being part of an ecosystem or creating their own ecosystems. This trend is observed for leading Tech companies, such as Apple, Google, Microsoft, and Alibaba, who have become platform ecosystem leaders. However, business ecosystems in energy are relatively less researched than other sectors, and many studies in the energy sector are still at the device or the system levels. A business ecosystem modelling framework is proposed by (Ma 2019) and applied in the energy sector with examples in (Ma et al. 2017, 2019). Although a business ecosystem architecture development methodology is proposed being part of the business ecosystem modelling framework (Ma et al. 2021), how to systematically analyze energy ecosystems and efficiently identify opportunities and solutions that can benefit the ecosystem and its stakeholders remain unclear.

The missing literature in business ecosystems research
The studies on the impact factors in business and strategies can be tracked from ETPS (Economic, technical, political, and social) (Aguilar 1967), STEP (Social, technical, economic, political) (Brown andWeiner 1984), andSTEPE (Social, technical, economic, political, andecological) (Davenport andPrusak 1997). Later on, many related acronyms are proposed whereas PEST becomes the most popular one. However, the main focus of these impact factors is individual and organizational strategies, and the business ecosystem perspective is not considered.
In the theory of business ecosystem, Moore (1993) states co-evolution in his definition of the business ecosystem as "organizations and individuals… coevolve their capabilities and roles and tend to align themselves in the ecosystem ". Later on, value co-creation and co-evolution become one of the primary research focuses, e.g., (Peltoniemi et al. 2004;Tanev et al. 2010). However, the indicators and assessment of ecosystem conditions have not been addressed systematically as in the ecological ecosystem domain. In the ecological ecosystem field, assessment and indicators of ecosystem conditions (European Union 2013) (Maes et al. 2018) and ecosystem change (Elmqvist et al. 2003) Open Access © The Author(s) 2022.

Based on the experience from the ecological ecosystem domain, the indicators and assessment of business ecosystem conditions are essential for understanding current ecosystem conditions, future ecosystem trends, and differences across business ecosystems.

EDITORIAL
From the system engineering perspective, system dynamics are used to identify attractors and properties of a system (Bousquet and Le Page 2004), represent, explore and simulate the complex feedback and interactions among system elements (Elsawah et al. 2017). However, the evolution/co-evolution perspective is rarely discussed although there are discussions in, e.g., system thinking (Rubenstein-Montano et al. 2001), machine logic (Polic and Jezernik 2005), or risk management/ assessment (Sage and Rouse, 2014).

CSTEP: five critical business ecosystems dimensions
Therefore, to fill the gap, five critical business ecosystems dimensions called CSTEP are proposed for systematically understanding a targeted business ecosystem: Climate, environment, and geographic situation. Societal culture and demographic environment. Technology (Infrastructure, technological skills, technology readiness). Economy and finance.
Policies and regulation. The CSTEP covers five influential dimensions that impact a specific business environment, and it is difficult to have universal definitions that apply to every business ecosystem. A general definition of CSTEP dimensions and sub-dimensions can be described as shown in Table 1. The explanation is based on the definitions from the Cambridge Dictionary and other authorities, such as NASA and United Nations.
Meanwhile, the five CSTEP dimensions can be divided into macro and micro levels based on the focuses (general or specific) of the business ecosystems. The main difference between these two is either from the ecosystem perspective or from the individual stakeholder perspective. For instance, for microgrid design, it is necessary to investigate the macro level of the C-dimension. Comparatively, for smart building development, the micro-level of the C-dimension is more important. Table 2 summarizes the general matters for each CSTEP dimension at both macro and micro levels in the energy domain.

The proposal of a novel CSTEP ecosystem analysis and evaluation method
The CSTEP has been applied in energy ecosystems with various cases, e.g., microgrid design (Ma et al. 2018) and evaluation of dynamic distribution tariffs (Christensen et al. 2021). These applications show that the CSTEP can be used to analyze energy ecosystems, identify opportunities & solutions and their impacts.
However, a methodology is needed to clearly introduce and elaborate the process to apply CSTEP for analyzing and evaluating business ecosystems. Based on previous studies, the methodology should cover three aims: • Business opportunity identification. By investigating unmet needs and megatrends in a given business ecosystem, the future/ideal ecosystems can be portrayed, and the correlated business opportunities can be identified.
• Technology feasibility evaluation. With defined CSTEP multi-dimensional criteria, selected technologies are evaluated based on their impacts on the business ecosystem. Therefore, technologies that can benefit the business ecosystem and its stakeholders the most will be adopted.  Finance relates to cost and revenue: •Cost, e.g., energy bill, labour, material (e.g. resources, raw material), maintenance (e.g., facilities), and service fees •Revenue, e.g., sales, income, compensation, Return-on-Investment Policies and regulation Policy: the activities of the government, members of law-making organizations, or people who try to influence the way a country is governed, e.g., •Climate agenda/goals •Political focus areas Regulation: an official rule or the act of controlling something, e.g •Laws •Regulations •Incentive/compensation scheme
