开发区升格政策能促进企业创新增量提质吗?

On the Effects of Elevation of Open Economic Zone on the Scale and Quality of Enterprise Innovation

通过构建多时点DID模型实证检验开发区升格政策对企业创新数量和创新质量的影响,结果表明:省级开发区升格通过降低制度性交易成本、提升市场化程度和加速创新要素流入对企业创新产出数量和产出质量产生促进作用,该政策对非民营企业、非高技术制造行业、高新区和小规模城市的作用效果更强。因此,要充分发挥开发区“以升促建”的创新激励效应,不仅要注重有为政府和有效市场的结合,还要根据城市固有经济特征优化开发区制度环境。

This paper constructs a DID model at multiple time nodes to empirically assess the impact of elevation policies of open economic zone at provincial level on the scale and quality of enterprise innovation.The results indicate that the elevation promotes both innovation output by reducing institutional transaction costs,enhancing marketization,and accelerating the inflow of innovation factors.Moreover,the effects are stronger in non private enterprises,non high-tech manufacturing industries,high-tech zones,and small-scale cities.Therefore,to fully fulfill the leading and exemplary role of the zones in"promoting construction through elevation",we must focus on the synergy between effective government and market mechanisms,and optimize the institutional environment of the zones based on the inherent economic characteristics of each city.
