摘要
伴随着科技带来生产力的巨大提升,数字经济成为推动经济增长的重要动力,衡量中国数字经济发展的状况显得愈发重要。在梳理各国数字经济政策和国内外对于数字经济测算文献的基础上,基于现有研究,提炼了数字经济的基础设施指数、产业指数、消费指数、社会指数、创新指数5个方面维度、10个分项维度以及32个基础指标,构建了中国数字经济指数的指标体系。运用熵权法确定基础指标权重后,又用主客观结合的赋权方法测算出2012—2021年中国数字经济的整体发展指数,得出不同地区5个方面维度的指数。比较中国各区域数字经济发展情况后,研究发现数字经济对区域发展具有较强的“扩散效应”。东部地区数字经济发展程度更高,但是增速较慢。中西部省份增速相对东部地区更快,不同地区数字经济发展速度呈现收敛趋势。为促进东中西部协调发展,相比发达地区,欠发达地区更应该加强数字经济方面的投入,加强数字基础设施建设,促进数字经济消费升级,改善数字经济社会服务,尤其要重视数字经济产业发展和推动数字经济关键技术创新。与此同时,东部地区要着重培育数字经济创新能力,提升数字经济产业发展水平。中国需充分发挥全国统一大市场优势,东中西部发挥各自比较优势,在数字经济时代获得更强竞争力和更大影响力。
The digital economy has become an important driver of economic growth,along with the huge productivity gains brought about by technology.Therefore,it has become increasingly important to measure the development of China’s digital economy.Based on the evaluation of digital economy policies in various countries and research on digital economy measurement at home and abroad,this paper extracts five dimensions of digital economy infrastructure index,industry index,consumption index,social index and innovation index based on existing research,including the level of network infrastructure penetration,infrastructure service capacity,degree of digital industrialisation,degree of digitisation of industry,level of digital financial development,digital payment capacity,degree of innovation input,innovation output capacity,and governmental development,digital payment capability,innovation input degree,innovation output capability,government service capability,Internet users’scale and information response speed,as well as the corresponding 32 basic indicators.The index system of China Digital Economy Index is constructed.By using the entropy weighting method to determine the weights of the basic indicators,the overall development index of China’s digital economy from 2012 to 2021 is measured with combining the subjective and objective assignment methods,which in turn resulted in five dimensional indices.Finally,comparing the development of digital economy in different regions of China,it is found that the digital economy has a strong“diffusion effect”on regional development.The eastern region has a higher degree of digital economy development,but the growth rate is slower.The central and western provinces are growing at a faster rate than the eastern regions,resulting in a convergence trend.Compared to developed regions and in order to promote the coordinated development of the East region,Central regions and Western regions,less developed regions should strengthen investment in the digital economy,enhance the construction of digital infrastructure,promote the upgrading of digital economy consumption and improve digital economy social services,with particular emphasis on the development of digital economy industries and the promotion of key digital economy technological innovations.The eastern region should focus on cultivating the innovation capacity of the digital economy and enhancing the development of digital industries.China should give full play to the advantages of a unified national market,and the eastern,central and western regions should give full play to their respective comparative advantages in order to gain stronger competitiveness and greater influence in the digital economy era.
