科技金融政策促进了地区经济增长吗?——来自地级市的经验证据

Does Science and Technology Finance Policy Promoted Regional Economic Growth?——Empirical Evidence From Prefecture-Level Cities

在创新驱动发展战略的背景下研究科技金融政策对区域经济增长的影响具有重要意义。本文基于2003—2018年我国289个地级市的微观数据,以两次设立的"促进科技和金融结合"试点作为准自然实验,运用双重差分法分析了试点设立对地区经济增长的影响。实证结果显示:与对照组相比,科技金融政策显著促进了实验组城市的经济增长,基准模型估计的结果在考虑了一系列其他干扰因素后,结果依然是稳健的;并且基于城市等级和城市区位视角的分组检验发现:试点设立均能显著促进高等级和低等级城市的经济增长,但低等级城市试点设立对经济增长的促进效果更明显;试点设立也能显著促进东部发达和中西部欠发达城市的经济增长,但中西部欠发达城市试点政策对经济增长的促进效果更明显。基于以上研究结论,本文进一步提出了促进地区经济增长的政策建议。

Under the background of innovation-driven development strategy,it is of great significance to study the influence of science and technology financial policies on regional economic growth.Based on the microcosmic data of 289 prefecture-level cities in China from 2003 to 2018,this paper took the pilot project of"Promoting the integration of science and Technology and finance"set up twice as a quasi-natural experiment,and analyzed the influence of the pilot establishment on the regional economic growth by using the double difference method.The empirical results showed that compared with the control group,the science and technology financial policies significantly promoted the economic growth of the experimental group.The results estimated by the benchmark model were still robust after considering a series of other interference factors.And based on the grouping test from the perspective of city level and city location,it is found that the pilot establishment can significantly promote the economic growth of both high-grade and low-grade cities,but the low-grade city pilot has more obvious promoting effect on economic growth.The pilot establishment can also significantly promote the economic growth of the developed cities in the east and the less developed cities in the central and western regions,but the pilot policies in the less developed cities in the central region have more obvious promoting effects on economic growth.Based on the above research conclusions,this paper further puts forward policy Suggestions to promote regional economic growth.
