江西省数字经济的测算及对制造业升级的作用机制研究

该文从数字基础、数字产业、产业数字和数字应用4个维度构建数字经济发展水平指标体系,测算了江西省11个地级市的数字经济发展水平,并实证分析了数字经济的发展对制造业升级的影响.研究结果表明:江西省数字经济处于发展阶段,存在“数字鸿沟”现象,南昌市数字经济水平远高于江西省其他地级市; 数字经济发展水平越高,制造业升级水平越高,同时居民工资水平、教育发展水平、固定投资水平和外资直接投资显著影响制造业升级.

The Study on the Measurement of Jiangxi Province's Digital Economy and Its Mechanism of Upgrading the Manufacturing Industry

The indicator system for the development level of the digital economy is constructed from the four dimensions of digital foundations,digital industries,industrial digital and digital applications.The digital economy development level of 11 prefecture-level cities in Jiangxi Province is measured,and the impact of digital economy development on the upgrading of manufacturing industry is analyzed empirically.The research results show that the digital economy of Jiangxi Province is in the development stage and there is a phenomenon of "digital divide".The digital economy level of Nanchang is much higher than others in Jiangxi Province.The higher the level of digital economy development,the higher the level of manufacturing upgrades.The level of educational development,the level of fixed investment,and foreign direct investment significantly affect the upgrading of manufacturing.
