摘要: 由于缺乏统一方法及参照系的比较,不同类型国家级开发区政策影响的结论莫衷一是。本文基于开发区设立的准自然实验,利用我国285个地级市2001—2018年数据,采用渐进性双重差分法,以相同对照组比较分析了国家级经开区和高新区设立对地区创新发展的影响。结果发现:国家级高新区对地区创新发展促进作用显著,而经开区无影响;机制分析表明国家级高新区设立提高了政府财政补贴和税收优惠,但只有财政补贴促进了地区创新发展;政策叠加效应分析证明国家级高新区设立对经开区城市样本亦存在创新促进作用;异质性分析显示国家级高新区设立对不同地区创新发展作用存在边际效应递减规律。

关键词: 国家级经开区, 国家级高新区, 创新发展, 双重差分

Abstract: Due to the lack of unified method and reference system for comparison, the existing researches often reach inconsistent conclusions on what influence different types of national development zones have through their policies. Based on the quasi-natural experiment of the establishment of development zones and the data of 285 prefecture level cities in China from 2001 to 2018, this paper uses the progressive difference-in-difference method to compare and analyze the influence of the establishment of national economic development zones and high-tech zones on regional innovation and development with the same control group as reference. The results show that national high-tech zones play a significant role in promoting regional innovation and development, while economic development zones have no influence in this regard. Mechanism analysis shows that the establishment of national high-tech zones improves government financial subsidies and tax preferences, but only financial subsidies promote regional innovation and development. The analysis of policy superposition effect shows that the establishment of national high-tech zones also plays an innovative role in promoting the urban samples of the economic development zone. Heterogeneity analysis shows that the establishment of national high-tech zones has descending marginal benefits to regional innovation and development.

Key words: national economic development zones, national high-tech zones, innovation development, difference-in-difference
