摘　　要：提升绿色全要素生产率是生猪养殖业实现高质量发展的一条重要路径,为助力生猪养殖业高质量发展,文章基于2004—2020年我国省级层面的生猪养殖业投入、产出数据,采用内生方向性产出距离函数测度了生猪养殖业绿色全要素生产率的变化,并使用新的方法对生猪养殖业绿色全要素生产率变化进行分解。结果显示:(1)2004—2020年,我国生猪养殖业绿色全要素生产率总体呈现增长态势,年均增长速度为3.2%。(2)生猪养殖业绿色全要素生产率增长来源于效率改善和技术进步,其中,技术进步是主要动力。(3)生猪养殖业的效率改善主要来源于发展效率改善,而技术进步主要来源于绿色技术进步。(4)发展动能和绿色动能均能促进生猪养殖业绿色全要素生产率增长,但绿色动能是主要因素。Improving green total factor productivity(GTFP) is an important path for the pig breeding industry to achieve high-quality development. In order to help the high-quality development of the pig breeding industry, this paper is based on the input and output data of pig breeding industry at the provincial level in China from 2004 to 2020, and uses the endogenous directional output distance function to measure the change of GTFP of pig breeding industry, and then adopts a new method to decompose the change of GTFP of pig breeding industry. The results go as below:(1) From 2004 to 2020, the GTFP of pig breeding industry in China showed an overall growth trend, with an average annual growth rate of 3.2%.(2) The GTFP growth of pig breeding industry comes from efficiency improvement and technological progress, among which technological progress is the main driving force.(3) The efficiency improvement of pig breeding industry mainly comes from the improvement of development efficiency,while the technological progress mainly comes from the progress of green technology.(4) Both development kinetic energy and green kinetic energy can promote the GTFP growth of pig breeding industry, but green kinetic energy is the main factor.
