【摘要】 2018年两会政府工作报告提出“发展壮大新动能”、“为数字中国建设加油助力”;十九大报告中提出“高质量发展是我们当前和今后一个时期确定发展思路、制定经济政策、实施宏观调控的根本要求”。当前,数字技术与各产业深度融合,互联网平台为各领域数据流通提供了高效便捷的传输通道,数字经济已成为推动传统产业转型升级、区域经济增长的核心动力。本文基于已有学者的研究,首先界定数字经济的内涵和特征,分析数字经济对经济增长的作用机理,同时研究欧盟、OECD为代表的世界组织及中国信息通信研究院为代表的国内政府及组织企业等构建的数字经济指标体系基础上,依据指标构建原则构建本文的数字经济指数体系框架。基于熵权法所得权重,进行指数加权测算得出中国区域数字经济指数。在此基础上,根据罗默知识溢出模型构建本文面板模型,实证研究数字经济对中国不同区域经济增长影响。最后,对各区域数字经济发展提出政策建议。论文的主要观点包含以下几点:根据数字经济指数测算结果,本文将31省份分为五大类(全面发展省份、快速超越省份、初见成效省份、起步阶段省份、观望探索省份)。其中“全面发展省份”是广东、江苏、山东、浙江、北京、上海;“快速超越省份”为河南、四川、福建、安徽、湖北、河北、湖南、天津、重庆;“初见成效省份”为辽宁、陕西、江西、广西;“起步阶段省份”为云南、内蒙古、黑龙江、山西、贵州、吉林;“观望探索省份”为新疆、甘肃、海南、青海、宁夏、西藏。其中,贵州、北京、重庆、安徽、西藏是数字经济增速最快的5个省份。第二,比较东部、中部和西部地区计量回归结果看出,中部和西部地区的数字经济指数系数基本一致,且高于东部地区。数据作为数字经济时代核心生产要素,数字经济突破地理条件限制,可推动中西部获得更多发展机遇。第三,从八大经济区域来看,黄河中游的数字经济指数系数最高。对于发展较为滞后的区域,要推动产业转型升级、实现在新领域中“弯道超车”,需要结合先进技术支撑,找准定位持续投入发展。在此基础上,文章提出如何推动我国区域数字经济发展相关的政策启示。更多还原

【Abstract】 The government work reports of the two sessions in 2018 proposed "development and growth of new momentum" and "fueling the construction of digital China";the report of the19 th National Congress stated that "high-quality development is our current and future period to determine development ideas,formulate economic policies,and implement macro The fundamental requirements of regulation and control".At present,digital technology is deeply integrated with various industries.The Internet platform provides efficient and convenient transmission channels for data circulation in various fields.The digital economy has become the core driving force for the transformation and upgrading of traditional industries and regional economic growth.Based on the research of existing scholars,this paper first defines the connotation and characteristics of the digital economy,analyzes the mechanism of the digital economy’s effect on economic growth,and at the same time studies the world organizations represented by the European Union and OECD and the domestic governments and organizations represented by the China Institute of Information and Communications Based on the digital economy index system constructed by enterprises,etc.,the digital economy index system framework of this paper is constructed according to the index construction principles.Based on the weights obtained by the entropy weight method,an index-weighted calculation is performed to obtain the China Regional Digital Economic Index.On this basis,the panel model of this paper is constructed based on the Romer knowledge spillover model to empirically study the impact of the digital economy on economic growth in different regions of China.Finally,policy recommendations are made for the development of digital economy in various regions.The main points of the paper include the following points: According to the results of the digital economic index calculation,this paper divides 31 provinces into five categories(full-scale development provinces,rapid surpassing provinces,provinces with initial results,provinces in the initial stage,and wait-and-see and explore provinces).Among them,"all-round development provinces" are Guangdong,Jiangsu,Shandong,Zhejiang,Beijing,Shanghai;"rapidly surpassing provinces" are Henan,Sichuan,Fujian,Anhui,Hubei,Hebei,Hunan,Tianjin,Chongqing;"provincials that have achieved initial results" are Liaoning,Shaanxi,Jiangxi,and Guangxi;"Provincial initial provinces" are Yunnan,Inner Mongolia,Heilongjiang,Shanxi,Guizhou,and Jilin;"Look and explore provinces" are Xinjiang,Gansu,Hainan,Qinghai,Ningxia,and Tibet.Among them,Guizhou,Beijing,Chongqing,Anhui,and Tibet are the five fastest growing digital economies.Second,comparing the results of quantitative regression in the eastern,central,and western regions,it can be seen that the digital economic index coefficients in the central and western regions are basically the same and higher than those in the eastern region.Data is the core production factor in the era of digital economy.The digital economy breaks through the restrictions of geographical conditions and can promote more development opportunities in the central and western regions.Third,from the perspective of the eight economic regions,the coefficient of the digital economic index in the middle reaches of the Yellow River is the highest.For regions with relatively slow development,to promote industrial transformation and upgrading and achieve "overtaking in corners" in new fields,it is necessary to combine advanced technical support,find a correct positioning and continue to invest in development.On this basis,the article puts forward policy enlightenment on how to promote the development of my country’s regional digital economy.更多还原
