自贸试验区与高技术产业研发投入——基于政府和企业投入的分析

Effect of Pilot Free Trade Zones on R&D Investment in High-Tech Industry--Based on Government and Enterprise Investment

本文采用多期双重差分模型,首先评估自贸试验区对政府和企业在高技术产业研发投入的影响及其异质性,然后考察自贸试验区通过哪些路径影响高技术产业研发投入。结果发现:(1)自贸试验区显著促进了政府对高技术产业的研发投入,但未能有效刺激企业对高技术产业的研发投入;(2)自贸试验区对政府在高技术产业的研发投入的促进作用仅在东部地区显著存在,而在中西部地区不明显;(3)自贸试验区显著促进了政府研发投入从非自贸试验区省份向自贸试验区省份转移,未能促进政府研发投入从非高技术产业向高技术产业转移;(4)自贸试验区显著促进了东部地区政府研发投入从非自贸试验区省份转向自贸试验区省份,但这一效应在中西部地区不明显。

This paper uses the multi-period difference-in-difference model to evaluate the impact and heterogeneity of pilot free trade zones on government and enterprise R&D investment in high-tech industries at first,then examine the pathways through which the pilot free trade zone influences the government s R&D investment in high-tech industries.The results are as follows.First,the pilot free trade zone has significantly boosted government s R&D investment in high-tech industries,but failed to stimulate enterprises R&D investment in high-tech industries effectively.Second,the promotion effect of pilot free trade zones on government R&D investment in high-tech industries only exists in the eastern region,but not in the central and western regions.Third,the pilot free trade zone has significantly promoted the transfer of government s R&D investment from non-pilot free trade zone provinces to pilot free trade zone provinces,and failed to promote the transfer of government s R&D investment from non-high-tech industries to high-tech industries.Fourth,the pilot free trade zone has significantly promoted government s R&D investment in eastern regions from non-pilot free trade zone provinces to pilot free trade zone provinces,but this effect is not obvious in central and western regions.
