数字经济时代来临，2020年，我国数字经济规模达到 39.2万亿元，对经济增长作用明显。我国产业数字化和数字产业化得到快速发展，数字产业化通过对数字技术、数据的创新，形成了许多新兴产业，对经济增长贡献度不断提升，但是我国地域广阔，地区数字产业发展差距明显，对我国各区域经济增长贡献不同。所以在数字经济快速发展的背景下，以新的角度看待区域发展差距和区域经济增长对各地区经济发展尤为重要。

全国各省份数字产业对经济发展的贡献不同，本文首先分析了各省份通信业、互联网行业、软件业、电子信息制造业对区域经济的影响现状，得出全国数字产业发展出现了多个增长中心，各区域内部差距明显。其次，以30省份2014-2020年的数据为研究对象分析了各省份数字产业发展效率，得出：一、全国数字产业效率大小为规模效率>纯技术效率>基础效率，技术和规模投入对数字产业及经济增长作用较大；二、数字产业发展效率存在省份差距，在全国形成了多处经济增长点。最后，通过多元线性回归模型和空间计量模型分别分析各省份导致数字产业对经济增长作用突出的因素，得出：一、影响各省份数字产业效率的投入要素不同，所以导致对经济增长的贡献有差距；二、部分省份数字产业拉动经济增长与相邻省份的辐射作用有关。综合全文研究，得出数字产业的发展对我国区域经济增长贡献明显，各省份经济增长不仅和本省数字产业投入有关，还与相邻省份数字产业的溢出效应有关，但地区发展差距较大，所以应根据自身发展现状，分别从增加数字投入要素、发挥数字产业集聚作用上实现区域经济增长。

The era of digital economy is coming. In 2020, the scale of my country's digital economy will reach 39.2 trillion yuan, which has a significant effect on economic growth. My country's industrial digitization and digital industrialization have developed rapidly. Digital industrialization has formed many emerging industries through the innovation of digital technology and data, and its contribution to economic growth has been continuously improved. However, my country has a vast territory, and there are obvious gaps in the development of regional digital industries, which contribute to different regional economic growth in my country. Therefore, in the context of the rapid development of the digital economy, it is particularly important for the economic development of various regions to view regional development gaps and regional economic growth from a new perspective.

The contribution of the digital industry to economic development varies among provinces across the country. This paper first analyzes the current situation of the influence of the communication industry, the Internet industry, the software industry, and the electronic information manufacturing industry on the regional economy in each province, and concludes that there are multiple growth centers in the development of the national digital industry, and the gaps within each region are obvious. Secondly, using the data of 30 provinces from 2014 to 2020 as the research object to analyze the development efficiency of the digital industry in each province, it is concluded that: 1. The efficiency of the national digital industry is scale efficiency>pure technical efficiency>basic efficiency. Technology and scale investment play a greater role in digital industry and economic growth; 2. There is a provincial gap in the development efficiency of the digital industry, and many economic growth points have been formed across the country. Finally, through the multiple linear regression model and the spatial econometric model to analyze the factors that lead to the prominent role of the digital industry in economic growth in each province, it is concluded that: 1. The input factors that affect the efficiency of the digital industry in each province are different, so there is a gap in the contribution to economic growth; 2. The economic growth driven by digital industries in some provinces is related to the radiation effect of neighboring provinces. Based on the research of the full text, it is concluded that the development of the digital industry has significantly contributed to my country's regional economic growth. The economic growth of each province is not only related to the investment in the digital industry in the province, but also related to the spillover effect of the digital industry in neighboring provinces. However, there is a large gap in regional development. Therefore, according to their own development status, regional economic growth should be achieved by increasing digital input elements and giving full play to the role of digital industry agglomeration.
