Abstract: The healthy development of technology innovation ecosystem in high-tech industries is critical to improving the national innovation ecosystem. Based on the description of the system health mechanism and the definition of system health concept, this study selects 24 influencing factors of system health, and uses the improved entropy weight method , the DEMATEL method and the ISM method to obtain the system health scores of 31 provinces in mainland China from 2011 to 2016 and analyze the key factors affecting health and the relationship between them. The results show that the score of system health is low in recent years, and there are regional differences among the eastern regions, the central regions and the western regions; the key influencing factors of system health include the proportion of enterprises with R&D institutions, international competitiveness, market demand, capacity for personnel adsorption, intellectual property protection, domestic competitiveness, foreign capital and the number of high-tech enterprises; the key cause factors include international competitiveness, market demand, capacity for personnel adsorption and intellectual property protection; the key result factors include the proportion of enterprises with R&D institutions, the number of institutions of higher learning, the authorization rate of invention patents and the sales rate of new products; the influence of the key cause factors on the middle-level factors and the key result factors should be given priority in the improvement of system health.

Key words: technology innovation ecosystem in high-tech industries, health, the improved entropy weight-DEMATEL-ISM method, key influencing factors

摘要： 高技术产业技术创新生态系统的健康发展对完善国家创新生态系统至关重要。本研究选取24个系统健康性影响因素,运用改进熵值-DEMATEL-ISM组合方法得出2011~2016年中国省际系统健康性得分,并对健康性关键影响因素及因素间的作用关系予以分析。结果表明,几年间系统健康性得分水平偏低且存在东部优于中部、中部优于西部的区域差异;系统健康性关键影响因素为有研发机构的企业数占比、国际竞争力、市场需求、对人员的吸附能力、知识产权保护、国内竞争力、引进外资和高技术企业数量;关键原因因素借助中层因素的中介传递作用影响关键结果因素最终影响系统健康的9条影响传递路径是关联广泛的主导路径,在改善系统健康性时应优先重视。
