数字经济支持实体经济的经验证据和机制检验——以长三角地区的实证检验为例

Empirical Evidence and Mechanism Test of Digital Economy Supporting Real Economy——Taking the empirical test of the Yangtze River Delta region as an example

发展好数字经济是促进长三角区域一体化和高质量发展的重要路径,本文测算出2011-2019年度长三角数字经济发展水平和实体经济发展水平,运用面板固定效应模型,实证分析长三角数字经济发展与实体经济之间的关系。研究发现,数字经济对实体经济具有“倒U型”特征的促进作用,且科技创新和金融发展水平是重要的传导机制,同时在不同区域和不同资源禀赋下具有异质性作用。本文为数字经济如何赋能长三角一体化高质量发展提供了新的思路和路径,也为如何促进实体经济更好发展提供了经验证据和有效建议。

Developing a good digital economy is an important path to promote regional integration and high-quality development in the Yangtze River Delta.this paper measures the development level of the digital economy and the real economy in the Yangtze River Del⁃ta from 2011 to 2019,and uses a panel fixed effect model to empirically analyze the relationship between the development of the digital economy and the real economy in the Yangtze River Delta.The study found that the digital economy has an“inverted U-shaped”pro⁃moting effect on the real economy,and technological innovation and financial development level are important transmission mecha⁃nisms,while having a heterogeneous effect in different regions and under different resource endowments.This article provides new ideas and paths for how the digital economy can empower the high-quality development of the Yangtze River Delta integration,as well as empirical evidence and effective suggestions on how to promote the better development of the real economy.
