科技政策组合的技术创新协同效应研究 ——供给侧—需求侧视角

利用2013-2016年中关村园区企业数据，将创新划分为创新倾向、技术绩效和经济绩效，以政策供给侧的政府补贴、税收优惠及需求侧的政府采购为研究对象，基于倾向得分匹配方法分析供需两侧科技政策组合的技术创新协同效应。结果表明：政策支持对技术创新存在激励效应，供给侧政策对创新倾向的激励效应最强，而需求侧政策对创新绩效的激励效应更显著；不同的科技政策组合形式均对技术创新具有激励作用，并且科技政策组合对技术创新存在协同效应。

Synergy Effects of Policy Mix in Technological Innovation

Based on the propensity score matching method, this paper analyzes the technical innovation synergy effects of policy mix between supply-side (government subsidies and tax incentives) and demand-side (government procurement) with the data of Zhongguancun Science Park enterprises from 2013 to 2016. Dividing innovation into innovation propensity，technical performance and economic performance, the result shows that the supports from government have incentive effects on technological innovation, and supply-side policies have a stronger effect on innovation propensity, while demand-side policies have a stronger effect on innovation performance. Meanwhile, different forms of science and technology policy mix have an incentive effect on technological innovation,and policy mix has a synergy effect on technological innovation. This paper contributes to a further understanding of the role government playing in the technological innovation, and provides micro-evidence for an objective evaluation of the synergy effects of supply-side and demand-side policies.
