东北振兴战略是否促进了经济结构调整?——基于PSM-DID方法的研究

Does the Northeast Revitalization Strategy Promote the Economic Structure Adjustment?A Study Based on PSM-DID Method

东北振兴战略作为中国区域协调发展总体战略的重要组成部分,对其实施效果的评价,不仅有助于客观认识其本身的实施成效,还有助于新一轮东北振兴战略和其他区域协调发展战略的有效实施。作者在1994~2015年中国202个地级市面板数据的基础上,采用双重差分倾向得分匹配法评估了东北振兴战略在促进经济结构调整方面的效应。研究发现,东北振兴战略既没有明显促进东北地区产业结构优化,也没有明显提高产业集聚水平。新一轮东北振兴战略,应注重区域政策设计的长期结构调整导向,改进区域政策设计的援助方式,提高区域政策执行的到位性和协同性,完善区域政策执行的体制和制度保障。

As an important component of the overall strategy of regional coordinated development in China,evaluating the effectiveness of the Northeast Revitalization Strategy（NRS）is of great benefit not only to objectively understand the effectiveness of itself,but also to the effective implementation of the new round of NRS and other regional coordinated development strategies.Based on the panel data of 202 cities from 1994 to 2015 in China,this paper evaluates the effect of NRS in promoting the economic structure adjustment using the Difference in Difference-Propensity Score Matching（PSM-DID）method.Our research find that the NRS improves neither the industrial structure optimization nor the level of industrial agglomeration of northeast region obviously.Therefore,in the new round of NRS,the government should pay more attention to the long-term structural adjustment and the more effective aid in regional policy design.It is also important for the government to improve the execution and cooperation efficiency,and set the system and mechanisms guaranteed for the regional policy implementation.
