双试点政策的协同创新效应

协同创新是提升创新体系整体效能的关键。基于中国2001—2020年280个地级市数据，将国家创新型城市试点政策和科技金融相结合试点政策作为一项准自然实验，采用渐进双重差分模型，实证检验实施双试点政策对城市创新水平的影响。研究表明：双试点政策组合能显著促进城市创新水平的提升。机制检验表明，双试点通过促进风险机构集聚、改善制度环境和发展金融科技提升了城市创新水平。进一步分析发现，双试点存在协同创新效应，双试点比单一试点能更有效地提升城市创新水平，且对先行实施创新型城市试点政策的城市和非东部地区的城市具有更强的影响效应。本研究探索了政策组合的协同创新效应，为完善城市创新治理体系提供政策启示。

Research on Synergistic Innovation Effect of Dual Piloting of Two Policies

Collaborative innovation is the key to improving the overall efficiency of the innovation system. Based on the data of 280 prefecture-level cities in China from 2001 to 2020, the national innovative city pilot policy and the pilot policy of combining science and technology finance are regarded as a quasi-natural experiment. The gradual double difference model is used to empirically test the impact of the implementation of the dual pilot policy on urban innovation level. The results show that the combination of pilot policies can significantly promote the improvement of urban innovation level. The mechanism test reveals that the dual pilot policy has enhanced the level of urban innovation by promoting the agglomeration of risk institutions, improving the institutional environment and developing financial technology. Further analysis finds that the dual pilot policy has a collaborative innovation effect. Compared with the single pilot policy, the dual pilot policy can improve the level of urban innovation more effectively, and has a stronger impact on the cities that implement the innovative city pilot policy and cities in the non-eastern region. This paper explores the collaborative innovation effect of policy mix, and provides policy enlightenment for improving the urban innovation governance system.
