知识溢出对区域创新的影响——基于创新政策的分析

doi:10.19571/j.cnki.1000-2995.2024.07.008

摘要/Abstract

摘要： 知识溢出是促进区域创新发展的引擎之一，而其对区域创新的影响却具有正负两面性，创新政策则能有效解决知识溢出的负作用。本文基于岭回归模型探究知识溢出对区域创新的影响以及创新政策在二者间的调节效应，通过系统动力学模型探究创新政策支持下知识溢出对区域创新影响的动态路径。研究发现：知识溢出能够显著促进区域创新，供给型、需求型、环境型创新政策均能对知识溢出与区域创新的关系产生正向调节作用，且溢出方的知识溢出对区域创新的影响更大，创新政策对接收方的知识溢出和区域创新的调节作用更强；进一步研究表明知识溢出是知识溢出方和接收方双向互促的过程，创新政策的实施能提升溢出方和接收方知识溢出对创新产出的正向影响，三类政策在其中的作用路径有所差异且政府采购政策和知识产权保护政策影响较大，金融支持政策影响相对较小。本研究从知识溢出方和接受方两方考察知识溢出对区域创新的影响机制及路径，揭示了创新政策在其中的作用，研究结论将为提升知识溢出对区域创新促进作用，以及创新政策的实施和完善提供经验证据和理论参考。

Abstract: Knowledge spillover is one of the engines that promote regional innovation and development, but its impact on regional innovation has both positive and negative effects. Innovation policies can effectively address the negative effects of knowledge spillover. The paper explored with the ridge regression model the influence of knowledge spillovers on regional innovation and the moderating effect of innovation policies, and studied with the system dynamics model the function paths of knowledge spillovers impacting on regional innovation supported by innovation policies. The results are as follows: knowledge spillover can promote regional innovation significantly, and the supply-oriented innovation policies, demand-oriented innovation policies and environmental innovation policies all have a positive moderating effect on the relationship between knowledge spillover and regional innovation. Moreover, knowledge spillover party has a greater impact on regional innovation, while the innovation policies of the knowledge receivers have a stronger moderating effect between knowledge spillovers and regional innovation. Therefore, knowledge spillover is a two-way process, in which the implementation of innovation policies can enhance the positive impact of knowledge spillover from both the spillover party and the spillover receiver on innovation output. The impact path of the innovation policies varies, and the government procurement policies and the intellectual property rights policies have a greater impact, while the financial support policies have a relatively smaller impact. The research examined the impact mechanism and path of knowledge spillover on regional innovation from both the knowledge spillover party and the spillover receiver, and revealed the role of innovation policies. The research findings will provide some empirical evidence and theoretical reference for enhancing the promoting effect of knowledge spillover on regional innovation, as well as implementing and improving innovation policies.
