中文摘要:
      近年来,我国生猪养殖市场受猪瘟疫情和环境规制的叠加影响,产生了剧烈波动。因此,国家推出多项扶持政策,促进了生猪养殖规模的不断扩大,同时也催生了对生猪养殖适度规模这一问题的思考。本文基于8省1484份生猪养殖户的调查数据,采用超然对数生产函数和C-D生产函数,从产出、效益和环境三个维度对生猪养殖规模效应进行实证研究。表明:生猪养殖规模与环境污染之间存在倒“U”型关系;综合考虑产出、效益和环境三个方面,适度规模应为年出栏1000~1999头;养殖经验对生猪养殖的产出和效益影响显著,环保认知和养殖户参加培训对污染排放影响显著。该研究结论对科学拓展生猪养殖规模、促进养殖行业绿色发展具有重要意义。
英文摘要:
      In recent years, China's pig breeding market by the outbreak of swine fever and environmental regulations of the overlay, has produced violent fluctuations. Therefore, the state launched a number of support policies, promoting the expansion of pig farming scale, but also gave birth to the pig breeding of the moderate scale of thinking. Based on the survey data of 1484 pig farmers in 8 provinces, this paper uses the Translog production function and the C-D production function to empirically study the scale effect of pig farming from the three dimensions of output, benefit and environment. It is shown that there is an inverted "U" relationship between pig farming scale and environmental pollution, and that, taking into account the output, efficiency and environment, the moderate scale should be 1000-1999 head per year; The conclusion of this study is of great significance to expand the scale of pig farming and promote the green development of the breeding industry.
