“双碳”目标下创新生态系统健康度评价及影响因素分析——基于熵值-DEMATEL-ISM法的实证研究

Evaluation of the health of innovation ecosystems under the“double carbon”goal and improvement path analysis:Empirical research based on entropy-DEMATEL-ISM method

近年来,创新生态系统成为企业主要的创新发展模式,为实现“双碳”目标,需要把减碳任务融入创新生态系统总目标,因此,如何将“双碳”目标融入企业创新生态系统健康度评价,是现阶段亟须研究的问题。文章结合“双碳”目标,构建出涵盖19个因素的创新生态系统健康度影响因素体系,运用熵值-DEMATEL主客观组合赋权法得出全部A股上市制造企业创新生态系统健康度得分,并通过DEMATEL-ISM方法对健康度影响因素的重要情况及因素间的层次结构模型进行分析。研究表明:企业创新生态系统健康度总体呈现逐步上升趋势,且存在明显地域差异;其关键影响因素有研发投入强度、研发投入增长率、主营业务收入等;根据层次结构模型,得出了7条影响因素传递路径,包括1条以根源因素主营业务收入为起点的主导路径。研究结论对企业改善创新生态系统健康度具有一定的借鉴意义,为“双碳”目标的实现提供新的对策与建议。

In recent years,the innovation ecosystem has become the main innovation development mode of enterprises.In order to realize the goal of“double carbon”,it is necessary to integrate the task of carbon reduction into the overall goal of the innovation ecosystem.Therefore,how to integrate the goal of“double carbon”into the evaluation of the health of the innovation ecosystem of enterprises is an urgent issue to be studied at this stage.In this paper,an innovative ecosystem health impact factor system covering 19 factors is constructed in combination with the goal of“double carbon”.All A listed manufacturing enterprises􀆳innovation ecosystem health scores are obtained by using entropy-DEMATEL subjective and objective combination empowerment method.The results show that the overall health of the innovation ecosystem of enterprises is gradually increasing,and there are obvious regional differences.The key influencing factors are the intensity of R&D investment,the growth rate of R&D investment and the revenue of main business.Based on the hierarchical model,seven influencing factors are derived,including a dominant path that starts with the revenue of the primary business.The conclusion of the study has some reference significance for enterprises to improve the health of innovation ecosystem and provides new countermeasures and suggestions for the realization of the goal of“double carbon”.
