This study aims to explore the direct effect and spillover effect of innovation policy in the distribution and dynamic evolution of the regional innovation from the perspective of innovation motivation using the spatial econometric model. Substantive innovation and strategic innovation in one region could affect innovation in another region. In addition, the direct effect and spatial spillover effect of innovation policy could significantly affect innovation; however, they exert a higher impact on substantive innovation. Considering different policy tools, we found that government subsidies exert a significant positive impact on substantive innovation and strategic innovation, whereas financial institution loans exert a significant negative impact on substantive innovation and strategic innovation. And for the impact range, the government subsidies are higher than that of financial institution loans. Furthermore, this study reveals the leading environmental factors affecting regional innovation and provide a policy basis to promote the construction of an innovation-oriented country.
本研究旨在运用空间计量模型，从创新动机的角度探讨创新政策在区域创新分布与动态演进中的直接效应和溢出效应。一个地区的实质性创新和战略创新会影响另一个地区的创新。此外，创新政策的直接效应和空间溢出效应会显著影响创新；然而，它们对实质性创新的影响更大。考虑到不同的政策工具，我们发现政府补贴对实质性创新和战略创新有显著的正向影响，而金融机构贷款对实质性创新和战略创新有显著的负向影响。在影响范围方面，政府补贴高于金融机构贷款。此外，本研究揭示了影响区域创新的主要环境因素，并为推动创新型国家建设提供了政策依据。
