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
