Introduction
With the further aggravation of environmental pollution and resource wastage, renewable energy plays an essential role in resource development, and renewable energy enterprises have emerged and have become an essential driving force for China's economic development.At the same time, the state advocates and encourages renewable energy enterprises to develop new technologies, break through the original technical barriers, and realize innovation.
Renewable energy enterprises realize the technological transformation of the first task, which is to continue to implement the green concept towards the green development of the innovation direction (Jiang et al. 2022).Green technological innovation refers to the optimization and upgrading of traditional technologies in the context of ecological civilization in order to achieve the goals of saving resources and energy and avoiding or mitigating ecological pollution and damage.Its core pursuit is to provide new products, processes, and technologies through innovation in order to promote the sustainable development of the ecological environment.The impact of green technology innovation on renewable energy enterprises is more far-reaching, and the factors affecting green technology innovation can be summarized into two categories: one is the internal factors, and the other is the external factors; the internal factors include green orientation and green technology capability (Lian et al. 2022).The paper importantly discusses the internal factors: enterprise green technology innovation knowledge, innovative R&D personnel, and green technology innovation policy.
There are several main reasons for studying the influencing factors of green technology innovation in renewable energy companies.First, in today's era, the Internet and big data make it easier and faster for companies to acquire, utilize, and share knowledge.It is easier for companies to initiate a series of innovative activities, which leads them to promote green technology innovation intentionally or unintentionally (Sun et al. 2024).Second, diversified technological and national knowledge, as well as relevant policymakers, are positively correlated with technological innovation.Access to crucial knowledge resources is a critical step for firms to be able to capitalize on the first development opportunities (Zeng et al. 2023;Hu et al. 2023a, b).Again, green technology innovation and renewable energy are effective in reducing carbon emissions; energy consumption utilizing second-generation panel technology effectively promotes green technology innovation (Gu 2024;Liu and Dong 2022;Li et al. 2023Li et al. , 2024)).Finally, appropriate environmental policies favor the development of green technology innovation (Wang and Wang 2024).Relevant economic policies and subsidies can incentivize enterprises to carry out green technology innovation (Li et al. 2022;Ma et al. 2023;Afum et al. 2023;Jiang and Liu 2024;Jiao et al. 2023).Green technology innovation has a catalytic effect on the development of renewable energy enterprises, which can improve the carbon emission performance of enterprises, alleviate the pressure brought by environmental problems, and thus improve the economic efficiency of enterprises (Wang et al. 2022(Wang et al. , 2023;;Tian et al. 2024;Qin et al. 2022;Zhang et al. 2023;Liu et al. 2024a, b).Therefore, it is of great significance to study the influencing factors of green technology innovation in renewable energy enterprises.
Previous studies on the influencing factors of green technology innovation in renewable energy enterprises are mainly based on empirical analysis or structural modeling, in which the amount of technological knowledge storage and the quality and quantity of technological innovation researchers affect the level of innovation (Huang et al. 2022;Liu et al. 2023;Chen et al. 2022;Rao et al. 2022;Zhu et al. 2023;Sun et al. 2022).Based on the content of green technological innovation (Feng et al. 2022;Lin and Jia 2020;Suki et al. 2022;Razzaq et al. 2021;Habiba et al. 2022;Obobisa et al. 2022), the relevant influencing factors of green technological innovation (Behera and Sethi 2022;Cao et al. 2022;Tasker and Scoones 2022;Cafarella et al. 2022;Malusà et al. 2022;Jorge et al. 2020), and the relevant influencing mechanisms of green technological innovation (Spurek et al. 2022;Zantow et al. 2022;Peng et al. 2019;Abbas and Sagsan 2019;Song et al. 2018;Diercks et al. 2019), hyper-networks have gradually appeared in the perspective and field of green technological innovation.Hypernetworks provide tools for studying other network relationships, and hypernetworks and hypergraphs have essential uses in the representation and operation of knowledge networks.With the development of global information technology and the expansion of channels connecting businesses, knowledge sharing through hypernetworks can facilitate business performance.In 1985, Sheffi first introduced the concept of splitting a complex network into multiple sub-networks in his study of urban transportation route networks by dividing the route pattern into two mechanisms, traffic service level, and traffic flow, which constrain each other in a balanced manner.Nagurney then clarified the concept of "Supernetwork" and its attributes, i.e., a network with multi-level, multi-dimensional, multi-attribute, coordination, and congestion characteristics, which is not only higher than the existing network but also beyond the existing network (Xi et al. 2019;Liu et al. 2024a, b).Scholars usually interpret it as a complex network consisting of multi-layered networks (network of networks).In other words, according to different research needs, a "supernetwork" decomposes the existing complex network with multiple attributes, layers, and dimensions into multiple sub-networks with a single attribute, layer, and dimension, which are interconnected and constrained by specific relationships.This kind of super network can present the changes of multiple attributes sub-networks more clearly and make the vast and messy complex network structure simple and straightforward (Pu et al. 2024;Suo and Guo 2017).
Therefore, this paper constructs a supernetwork model to analyze the role of influencing factors on the green technological innovation of renewable energy enterprises based on the supernetwork model and simulation results, based on the analysis of innovative members' participation in the process of corporate knowledge-sharing under the influence of innovation policy.

Study design
Adopting Netlogo for hyper-network dynamic simulation, firstly, using the similarity characteristics of complex networks, we study the network abstraction of object system confrontation, and abstract the confrontation process into the relevant elements of dynamic evolution; secondly, according to the abstracted elements, we formulate the corresponding constraint rules of dynamic evolution to guide the behaviors and interactions of each node or activity in the simulation process (Gang et al. 2019); thirdly, based on the multi-subjective modeling function of Netlogo, we create the hyper-network model, and define the behaviors and interaction principles of each subject; lastly, we run the model and observe the process of its dynamic evolution (Hu et al. 2023a, b).

Member participation in innovation knowledge sharing model construction
The three factors influencing innovation are studied in the preparation stage, implementation stage, operation stage, and feedback enhancement stage.As shown in Fig. 2.

Preparation stage
A series of preparatory work was done for the successful completion of knowledge sharing: (1) Network modeling, where members screen relevant knowledge in each innovation policy that is beneficial to the technological innovation of renewable energy enterprises.The cornerstone of the construction of the supernetwork model of knowledge sharing lies in the study of knowledge elements and knowledge subjects.( 2) Send out knowledge-sharing requests, members will intentionally take the initiative to send out knowledge-sharing requests to the knowledge-sharing center.
(3) Knowledge query: after receiving the request, the sharing center will search for knowledge nodes in the knowledge-sharing network and provide knowledge to the requesting object if the knowledge node is included in the sharing network or provide the knowledge node with high relevance to the requesting object if it is not included.(4) Screening knowledge providers, screening those that are conducive to innovation and development among many providers, and sending knowledge-sharing requests to them.

Implementation phase
The sign of the beginning of knowledge sharing is that the knowledge owner accepts the knowledge-sharing request from the knowledge receiver, and the methods of knowledge sharing are mainly two kinds: online primarily transmits knowledge through social software and emails; offline mainly through face-to-face communication between the two parties, paper documents, on-site guidance, etc.In the process of sharing knowledge, two types of knowledge can be found, namely, tacit knowledge and explicit knowledge (Hussain et al. 2020).Explicit knowledge and implicit tacit knowledge can be transformed into each other, and there is also a mutually transformable relationship between the same type of knowledge, implicit or explicit.The process of transformation of knowledge in another kind or itself completes the transfer and sharing of knowledge between both the owner and the receiver.

Operation phase
At the end of the sharing, the party receiving the knowledge adjusts the related technological innovation work according to the shared knowledge content.It applies the new knowledge to the original technological innovation link.

Feedback enhancement phase
Based on the operation, we provide feedback on the already existing knowledge-sharing situation, generate new knowledge in conjunction with the sharing status, implement dynamic guardianship to fix potential problems, and update the entire knowledge-sharing network in a timely manner.

Research methodology
Simulation

Simulation hypothesis
Hypothesis 1 Assume that there are three heterogeneous nodes of knowledge, members, and policies and six-element relationships in the system.
Hypothesis 2 Assume that member nodes possess one or more kinds of knowledge and the total amount of knowledge owned by member nodes is greater than the total amount of knowledge requested by policy nodes.
Hypothesis 3 Assume that members randomly select a policy solution from the list of knowledge providers to send knowledge sharing requests, and the policy must provide corresponding knowledge sharing.
Hypothesis 4 Assume that after the knowledge-sharing is completed, the storage of knowledge and the individual influencing factors of members will be elevated accordingly according to the sharing completion result.
Hypothesis 5 Assume that the condition for the emergence of new knowledge nodes is established on the basis that the storage of old knowledge nodes exceeds the threshold value and its its knowledge storage decreases, and the condition for the emergence of new member nodes is established on the basis that the value of each influence factor of old members exceeds the threshold value, and the value of each influence factor itself decreases accordingly.

Simulation steps
Step 1 Data collection: data related to knowledge, members and policies are collected and coded.
Step 2 Establish the knowledge sub-network, member sub-network, and policy sub-network based on the data and coding, and establish the mapping relationships among the networks.
Step 3 The member sends a knowledge-sharing request to the knowledge-sharing center, and the sharing center first searches for the knowledge in the knowledge sub-network, then searches for policies with mapping relationships with the knowledge in the policy sub-network and sends the list of policies with mapping relationships to the members.
Step 4 If there is no policy with mapping relationship with the knowledge, it searches for the knowledge with the highest degree of association in the knowledge subnet and repeats Step3.
Step 5 After members receive the list of policies with mapping relationships, they send knowledge-sharing requests to the policies and start knowledge-sharing.

Simulation data
The study was carried out by means of field research and questionnaire distribution.The survey respondents are middle and senior managers of renewable energy enterprises distributed in the eastern region of China, with rich experience in enterprise management and knowledge accumulation in renewable energy.A total of 600 questionnaires were distributed in this survey, and the questionnaires with blanks, incomplete answers, consecutively choosing the same answer, and answers with obvious patterns or errors were defined as invalid questionnaires.After eliminating 156 invalid questionnaires, a total of 444 valid questionnaires were obtained, and the effective recovery rate of the questionnaires was 74%.In actuality, the central surveyed enterprises are small and medium-sized, the establishment years are concentrated in 3-5 years, and the employees' working years are mostly 3-5 years.The average survey data was selected for this study.
The data of listed companies of manufacturing companies are selected from annual reports of listed companies, a yearly library of data of listed companies, etc., and the results are obtained through simulation, which is consistent with the results obtained from the questionnaire.
Therefore, a hypernetwork model containing ten knowledge nodes, 20 member nodes, and 15 policy nodes is constructed.The amount of knowledge stored in each knowledge node and the trust level of each member node are shown in Tables 1 and 2.

Simulation experiments
The Netlogo platform is used for simulation analysis.A knowledge-sharing hyper-network model containing 10 knowledge nodes, 20 member nodes, and 15 policy nodes is established, as shown in Fig. 3, in which the round nodes are knowledge nodes, the yellow "human-shaped" nodes are member nodes, and the red "human-shaped" nodes are policy nodes.The lines between the nodes represent the relationship between homogeneous nodes and the mapping relationship between heterogeneous nodes.
The results of the model are shown in Fig. 4.Under the condition of the clock counter ticks = 460, the total storage of technological innovation knowledge of renewable energy enterprises changed from 18.9 to 64.1 after the sharing of knowledge by the innovation policy, and the number of new knowledge nodes and new member nodes was increased by 11 and 9, respectively.The first new renewable energy enterprise technology innovation knowledge node appeared at time = 20, and the first new renewable energy enterprise technology innovation membership node appeared at time = 13.This suggests that knowledge sharing enhances the total storage of innovation knowledge, increases the number of new knowledge nodes and new member nodes, and speeds up the generation of new knowledge nodes and new client nodes.

Conclusions and shortcomings
Figure 33 shows the relationship of innovation influencing factors derived from the simulation.The results show that: (1) In terms of innovation, the green technological innovation of enterprises is enhanced with the improvement of knowledge-sharing ability, indicating that innovation knowledge-sharing has a driving effect on green technological innovation.
(2) In terms of innovative members, the green technology innovation ability of renewable energy enterprises improves with the increase in the proportion of six factors, such as the sharing personality of members, the frequency of communication between members, and the trust of members in the team, thus indicating that the six factors have a positive and significant impact on the green technology innovation of renewable energy enterprises.(3) In terms of innovation policies, seven innovation and economic policies about renewable energy, such as reasonable reduction of income tax policy on technological innovation, encouraging economic policy, carbon peak, carbon neutral policy, etc., were selected.The newborn knowledge nodes, member nodes, and total knowledge in the comparison between simulation results and original simulation results significantly improved compared to the original conditions.It was found that the increase of relevant policies would stimulate renewable energy enterprises' innovation in green technology and strengthen their innovation ability.
This paper mainly investigates the factors that influence green technology innovation through innovation knowledge, innovation R&D personnel, and innovation policy.Other aspects should be covered.There are some shortcomings for the hypothetical conditions of the simulation: the policy node can also be increased by one unit when the knowledge node and membership node grow to a certain magnitude subsequently.These two aspects will continue to be improved in future studies.Meanwhile, this study focuses on the positive impacts of green technology innovation and ignores potential negative factors or barriers that may hinder innovation.Possible challenges, such as financial constraints, regulatory barriers or market competition, will be discussed in future studies with a view to providing a more balanced picture of the innovation landscape.

Countermeasures and recommendations
Based on the above simulation results, the following countermeasures are proposed: ( The government can strengthen the publicity and interpretation of innovative economic policies, and guide enterprises to make full use of the support and preferential policies of relevant policies, so as to increase their motivation and investment in green technology innovation.
The hyper-network model can be considered for application in the field of transportation in the future for optimizing the logistics network, traffic flow management, and the design of intelligent transportation systems.By analyzing the relationship between different transportation nodes and paths, transportation efficiency and safety can be improved.In manufacturing, hypernetwork models can be used to optimize supply chain management, production processes, and resource allocation.By analyzing the interaction and knowledge sharing between different manufacturing units, production efficiency and innovation can be improved.In addition, the hypernetwork model can be applied to traditional energy industries, such as oil, gas, and nuclear energy, to increase the efficiency of energy production and distribution and to reduce environmental impacts.
