数字经济驱动典型工业化城市转型升级的实证研究—以国家产业转型升级示范区为样本

An Empirical Study on Digital Economy Driving Transformation and Upgrading of Typical Industrialized Cities: Taking the National Industrial Transformation and Upgrading Demonstration Zones as a Sample

摘要:

典型工业化城市是新时代区域协调发展和新型城镇化的重点地区。国家通过设立产业转型升级示范区，以点带面推动典型工业化城市高质量发展取得显著成效。分析数字经济通过生产、消费、交换、分配等环节影响产业结构合理化和高级化的机制，采集示范区所在27个地级市2012到2019年的面板数据，使用全局熵值法构建数字经济发展水平指数，实证检验数字经济对典型工业化城市产业转型升级的水平，以及对其产业转型速度、产业结构高级化、产业结构合理化的影响。利用被解释变量滞后一期作为工具变量解决内生性问题，结果依旧显著。实证结果表明，数字经济能显著推动典型工业化城市的产业转型升级，能够推动产业转型速度提高和产业结构高级化，但在推动产业结构合理化方面并不显著；数字经济对老工业城市的推动作用要高于资源型城市。基于实证结论提出数字经济助推典型工业化城市转型升级的政策建议。

Abstract:

Typical industrialized cities are the key areas of regional coordinated development and new urbanization in the new era. The state has achieved remarkable results in promoting the high-quality development of typical industrialized cities through the establishment of industrial transformation and upgrading demonstration zones. Analyze the mechanism of digital economy affecting the rationalization and upgrading of industrial structure through production, consumption, exchange, distribution and other links , collect the panel data of 27 prefecture level cities where the demonstration zones are located 2012 to 2019, use the global entropy method to construct the digital economy development level index, and empirically test the impact of digital economy on the level of industrial transformation and upgrading of typical industrialized cities, as well as its impact on the speed of industrial transformation, the upgrading of industrial structure and the rationalization of industrial structure. Using the explained variable lag period as an instrumental variable to solve the endogenous problem, the result is still significant. The empirical results show that digital economy can significantly promote the industrial transformation and upgrading of typical industrialized cities, improve the speed of industrial transformation and upgrade the industrial structure, but it is not significant in promoting the rationalization of industrial structure; The role of digital economy in promoting old industrial cities is higher than that of resource-based cities. Based on the empirical conclusions, this paper puts forward policy suggestions for digital economy to promote the transformation and upgrading of typical industrialized cities.
