基于生态位适宜度的区域创新生态系统与创新效率研究

由于区域内创新资源的有限性，区域创新生态系统中创新主体生态位之间的重叠程度对创新效率的影响愈发的显著，基于此本文运用生态位适宜度评价模型对我国30个省市 2011~2015 年的创新生态系统适宜度水平进行了测度，并分别与运用超效率数据包络分析法所测得的区域知识创新效率和产品创新效率进行了面板数据的回归分析。结果显示，区域创新生态系统的生态位适宜度对两个阶段的创新效率均具有正向的相关关系，但这种影响只具有短期的时间维度，并不存在两年及以上的相互作用。区域创新生态系统的对外开放会对产品创新阶段的创新效率产生负面影响，同时会促进知识创新阶段创新效率的提高。最后，在协调系统内部各生态位之间的发展关系时，应注重区域内经济发展水平对两个阶段创新效率的促进作用。

Research on Regional Innovation Ecosystem and Innovation Efficiency Based on Niche Adaptability

Due to the limited resources of the region，the degree of overlap between the innovation niche in the regional innovation ecosystem has become more and more signi?cant. In this paper，the niche suitability evaluation model is used to measure the level of suitability of innovative ecosystems in 30 provinces and cities in China from 2011 to 2015，and the regional knowledge innovation ef?ciency and products measured by super-ef?ciency data envelopment analysis innovation ef?ciency of the panel data regression analysis.The results show that the niche suitability of regional innovation ecosystem has positive correlation with the innovation ef?ciency of the two stages，but this effect only has short - term time dimension，and there is no two - year or more interaction.The opening of regional innovation ecosystem will have a negative impact on the innovation ef?ciency of product innovation stage，and will promote the innovation ef?ciency of knowledge innovation stage. Finally，in the coordination of the development of the relationship between the various niches within the system，we should pay attention to the level of economic development in the region to promote the ef?ciency of the two stages of innovation.
