Spatial effect of digital technology enabling high-quality development of China's dairy industry
This paper constructed an evaluation index system for the high-quality development of dairy industry from five dimensions:industrial benefit,main income,production efficiency,quality and safety,and ecological environment,and empirically tested the high-quality development and spatial effects of digital technology enabling dairy industry in 31 provinces in China from 2014 to 2020.The results showed that there were sig-nificant differences in the level of high-quality development of the dairy industry in China.The level of high-quality development of the dairy in-dustry in Shanghai,Hubei and Hainan was high,while that in Tianjin,Hebei,Inner Mongolia,Jiangsu,Anhui and Guizhou was rapid,while that in Guangdong,Xizang and Fujian was relatively low;Digital technology could significantly promote the high-quality development of dairy industry.Among them,the promotion effects of digital technology informatization and interconnection were 0.979 3 and 8.637 9 respectively;Digital tech-nology could significantly promote industrial structure optimization,development momentum cultivation,production efficiency improvement,e-cological environment and social welfare improvement of dairy industry;The promotion effect of digital technology on the high-quality develop-ment of dairy industry showed an"inverted U"shape,the impact of digital technology on the high-quality development of dairy industry de-creased first and then increased with the improvement of the high-quality development level of dairy industry;Digital technology enabling high-quality development of dairy industry had obvious spatial spillover effect.The direct effect,indirect effect and total effect were 15.31％,21.86％and 37.17％,respectively.Based on the above conclusions,the paper put forward some suggestions on digital technology to promote the high-quality development of dairy industry.
