Research and Suggestions on the Impact of Digital Economy on the Optimization and Upgrading of Service Industry in Yangtze River Economic Belt

随着网络的普及，大数据、云计算、物联网、5G技术逐步成熟，数字经济在全球范围内快速发展。与此同时，我国数字经济基础建设大体框架已经建设完毕，数字经济发展活力不断增强，为我国产业的优化升级提供了有力的技术支持。近年来，我国服务业规模日益壮大，综合实力不断增强，质量效益大幅提升，新产业新业态层出不穷，逐渐成长为国民经济第一大产业，但现阶段内，我国服务业也存在着产业结构不合理、质量产量与发达国家差距明显等问题。由于长江经济带横跨我国东中南三大区域，具有独特优势和巨大发展潜能，因此本文选择长江经济带作为区域研究的代表，研究数字经济发展对其服务业优化升级的影响并提出促进服务业结构优化升级的合理化建议。With the popularity of the network, big data, cloud computing, Internet of Things, and 5G technologies are gradually maturing, and the digital economy is developing rapidly on a global scale. At the same time, the general framework of China’s digital economy infrastructure has been completed, and the development vitality of the digital economy has been continuously enhanced, providing strong technical support for the optimization and upgrading of China’s industries. In recent years, the scale of China’s service industry has been growing, the comprehensive strength has been continuously enhanced, the quality and efficiency have been greatly improved, new industries and new formats have emerged in an endless stream, and gradually grown into the largest industry of the national economy. However, at this stage, China’s service industry also has problems such as unreasonable industrial structure and obvious gap between quality and output and developed countries. As the Yangtze River Economic Belt spans the three regions of East and South China and has unique advantages and huge development potential, this paper chooses the Yangtze River Economic Belt as a representative of regional research, studies the impact of digital economy development on the optimization and upgrading of its service industry, and puts forward reasonable suggestions to promote the optimization and upgrading of service industry structure.
