摘要
数字经济是长江经济带发展新质生产力的着力点。本文基于长江经济带11省(直辖市)(1)2013-2020年的面板数据,利用多种方法对长江经济带数字经济发展水平进行测度并总结其时空特征,采用动态空间杜宾模型探索各因素对数字经济的影响程度。结果表明:(1)样本期内长江经济带数字经济发展水平持续增长的同时差异逐年缩小;(2)数字经济发展水平表现出正向空间溢出效应,整体具有“下游恒高上中游略低”的特征,局部以高—高聚集与低—低聚集为主;(3)产业结构升级、开放水平提高、城乡协调发展、教育水平与城市化建设强度提升有利于促进数字经济发展,并产生正向空间溢出效应。鉴于此,提出完善数字经济政策体系、坚持一体化与差异化战略相结合、加大关键核心技术研发力度等建议。
The digital economy is a key focus for the development of new productive forces in the Yangtze River Economic Belt.This paper is based on panel data from 11 provinces(municipalities)in the Yangtze River Economic Belt from 2013 to 2020,using a variety of methods to measure the level of digital economy development in the Yangtze River Economic Belt and summarize its temporal and spa-tial characteristics.A dynamic Spatial Dubin Model is employed to explore the impact of various factors on the digital economy.The results show that:(1)During the sample period,the level of digital economy development in the Yangtze River Economic Belt continues to grow,and the differences among regions are gradually narrowing;(2)The development level of the digital economy shows a positive spatial spillover effect,generally characterized by"a consistently high level in the downstream and slightly lower in the upper and middle reaches,"with high-high and low-low aggregation being the main patterns;(3)The upgrading of industrial structure,the improvement of openness level,the coordinated development of urban and rural areas,the enhancement of education level,and the intensification of urbanization con-struction are all conducive to the promotion of digital economy development and generate positive spatial spillover effects.In view of this,suggestions such as improving the policy system for the digital economy,combining integrated and differentiated strategies,and increasing the research and development efforts of key core technologies are proposed.
