Output Efficiency Difference of Digital Economy in China's Three Industries
Based on the input-output data of 31 provinces,autonomous regions and municipalities in China from 2012 to 2017,the BCC-DEA model is constructed to calculate the output efficiency of digital economy of three industries in each province and makes a comparative analysis.The results show that:In terms of industrial types,compared with 2012,the digital economy output efficiency of the first industry in China decreased in 2017,the performance of the secondary industry was relatively stable,while the tertiary industry increased slightly;As for these provinces,autonomous regions and municipalities,the number of them with the best digital economy output efficiency in first industry decreased from 9 in 2012 to 6 in 2017,only Shanghai,Jiangsu and Yunnan maintaining the optimal level,five provinces had the best output efficiency of digital economy in the secondary industry,among which Tibet,Shaanxi,Ningxia and Xinjiang maintained the optimal level all the way,and in 2012,there were 7 provinces autonomous regions and municipalities with the best digital economic output efficiency of the tertiary industry,and there were 10 in 2017,among which Shanghai,Xizang and Ningxia maintained at the best level;From a regional perspective,the digital economy output efficiency of the three industries in the East basically ranked in the forefront of the whole country,and the development level of the national digital economy showed the feature of progressive decrease from East to West.
