承接产业转移与区域创新能力——基于国家级承接产业转移示范区的准自然实验

Undertaking Industrial Transfer and Regional Innovation Capacity:The Quasi-natural Experiment Based on the National Industrial Transfer Demonstration Area

聚焦国家级承接产业转移示范区设立对区域创新能力的影响、作用机制及其空间溢出效益,为增强相关政策实施效果、推动区域创新能力提升提供参考。以2007—2019年我国中西部162个地级市为样本,运用多时期双重差分和空间双重差分模型进行实证检验,结果表明:国家级承接产业转移示范区设立可显著增加区域创新数量,并提升以实质性创新和绿色创新表征的创新质量能力,但其促进作用在不同区域、承接地是否明确具体的转移产业来源区域以及示范区所处发展特征等方面存在异质性,且具有显著的空间溢出效应;其中主要通过产业结构调整和地方政府竞争两种作用机制来提高区域创新能力。因此,我国各地应继续积极打造良好的承接产业转移发展环境,在承接转移产业过程中注意明确划定承接产业类型、关注创新质量,并通过合理布局、优化产业结构发挥国家级承接产业转移示范区的增长极作用,带动区域创新能力共同发展。

This paper focuses on the impact,mechanism and spatial spillover benefits of the establishment of national industrial transfer demonstration zones on regional innovation capacity,so as to provide reference for enhancing the implementation effect of relevant policies and promoting the promotion of regional innovation capacity.Taking 162 prefecture-level cities in central and western China from 2007 to 2019 as samples,it makes an empirical test by using multi-period DID and SDID models.The results show that:the establishment of national industrial transfer demonstration area can significantly increase the number of regional innovation,and improve the innovation quality capability represented by substantive innovation and green innovation,however,its promotion effect is heterogeneous in different regions,whether the specific transfer industry source area is clear and the development characteristics of the demonstration zone are located,and it has a significant spatial spillover effect.Therefore,all parts of China should continue to actively create a good development environment for undertaking industrial transfer,pay attention to clearly defining the types of undertaking industries and paying attention to the innovative quality in the process of undertaking industrial transfer,and give play to the growth pole role of national demonstration zones for undertaking industrial transfer through rational layout and optimization of industrial structure,so as to promote the common development of regional innovation capabilities.
