摘要
文章从产业效益、主体收益、生产效率、质量安全、生态环境5个维度构建奶业高质量发展评价指标体系,实证检验2014～2020年我国31个省份数字技术赋能奶业高质量发展及空间效应.结果表明,我国奶业高质量发展水平存在显著差异性,其中上海、湖北和海南奶业发展水平较高,天津、河北、内蒙古、江苏、安徽、贵州等地奶业发展迅速,广东、西藏、福建等地区奶业高质量发展水平相对较低;数字技术能够显著促进奶业高质量发展,数字技术信息化和互联化的促进作用分别为0.9793和8.6379;数字技术能够显著促进奶业产业结构优化、发展动能培育、生产效率提高、生态环境及社会福利改善;数字技术对奶业高质量发展的促进作用呈"倒U"型,即数字技术奶业高质量发展的影响随着奶业高质量发展等级的提高呈现先降后增;数字技术赋能奶业高质量发展具有明显的空间溢出效应,其直接效应、间接效应和总效应分别为15.31％、21.86％及37.17％.基于上述研究结论,提出数字技术促进奶业高质量发展建议.
Abstract
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.
