国家高新区:“体制回归”还是创新发展——基于地方政府供地行为的考察

National High-Tech Zones: "System Return" or Innovative Development——An Investigation Based on the Land-Supply Behaviour of Local Governments

以地方政府产业用地供给为切入口,利用多期双重差分模型对国家高新区设立如何影响地方政府供地行为进行了检验,并分析了国家高新区设立对地区经济增长、创新发展水平的影响。研究发现,总体而言,国家高新区的设立加剧了地方政府无差别供地的行为倾向,出现明显的"体制回归"现象,且其会因国家高新区所处地区经济发展水平、城市行政等级等存在异质性特征而呈现差异化表现。进一步的分析表明,目前国家高新区仍主要是通过吸引要素简单集聚的途径带动所在城市的经济增长,未能有效实现向创新驱动发展模式的转变。

Taking the industrial land supply of local governments as the entry point, the paper used the multi-period DID model to test how the establishment of national high-tech zones has affected the land supply behavior of local governments, and further analyzed its impact on local economic growth and the level of innovative development. The results showed that, in general, the establishment of national high-tech zones has intensified the behavioral tendency of undifferentiated land supply of local governments,so there was the obvious phenomenon of "system return". Meanwhile, the effect of the establishment of national high-tech zones may differ along with the heterogeneous characteristics of regional economic development level and city administrative level. Further analysis showed that, national high-tech zones have driven city economic growth mainly through the path of the simple agglomeration of factors, and they haven’t effectively realized the transformation to the innovation-driven development mode.
