Evaluating China's Digital Economy Development Level Based on Entropy Weight TOPSIS
Currently,digital economy has become an important engine for China's economic transformation.In this paper,the evaluation index system of digital economy is constructed from five dimensions regarding digital infrastructure,digital innovation,industrial digitalization,digital industrialization and digital governance.By using the entropy-weight TOPSIS method,this paper makes an empirical evaluation and analysis of the development level of digital economy in 30 provinces in China from the regional and provincial levels,and classifies and analyzes the development level of digital economy by K-means clustering algorithm.The results show that the development of digital economy is uneven among regions in China.Among them,Beijing,Guangdong,Shanghai,Zhejiang and Jiangsu are in a leading position,but the development level of digital economy in most provinces are below the national average level and unable to enjoy"digital dividend".Moreover,the there is a serious problem of"digital divide"among regions in China,and the distribution of China's inter-regional digital economy development level presents a pattern from high to low from eastern to central,and then to western and northeastern regions.
