中国高新区的赶超路径及影响因素研究

Research on the Catch-up Routes and Influencing Factors of High-tech Zones in China

本文在分析高新区赶超路径的基础上,以52个国家级高新区作为样本,采用系统GMM方法研究了中国高新区的赶超问题。结果表明:中国高新区赶超具有显著的固定资本驱动特征,但是这一特征正在弱化,而全要素生产率的贡献正在上升;加工制造业资本集聚是中国高新区赶超的重要动力,在外资集聚区和传统工业区样本中体现得尤为突出;高新区后期出现的全要素生产率改善主要是由资本深化引起的,这意味着既有模式下中国高新区的赶超仍会沿着经济规模扩张轨道进行,难以向创新驱动的内生发展轨道转换。根据研究结果,提出了相应的政策建议。

This article offers econometric tests of the catchup routes of 52 national grade hightech zones by using system GMM. The re suits show that the growth of hightech zones was mainly driven by the formation of fixed capital. The driving forces from the formation of fixed capital declined while the driving forces from total factor productivity rose. The catchup of 52 national grade hightech zones was driven by the agglomeration of manufacturing capitals, especially in the FDI intensive areas and traditional manufacturing areas. The catchup routes embodies technical progress from the promotion of TFP, which means the hightech zones would evolve along the path of scale expansion instead of endogenous growth. Some suggestions are provided according to the results.
