摘要
以生猪养殖业发展数据及产排污基本技术经济参数等为支撑,运用SFA-Malmquist等方法,定义粪污资源化利用效率和环境全要素生产率等指数,分析了2006—2017年中国生猪养殖粪污资源化利用效率及其趋势。研究表明:中国生猪养殖业仍属于“资本投入型”产业,粪污资源化高效利用和适度规模化养殖是生猪养殖经济绿色增长的关键;环保约束下生猪养殖环境全要素生产率增速放缓,其增长具有规模异质性、时变特征和区域特征,环境全要素生产率在不同规模间的主要驱动因素不同,技术效率与技术进步存在此消彼长的特征,中规模具备增长潜力,而大规模的增长优势显著下降;中国生猪养殖业的绿色发展务必兼顾粪污资源化利用效率与养殖技术效率,同时注意不同规模在不同养殖发展区的优势。
Supported by the data of the pig breeding industry development and the basic technical and economic parameters of pollution production and discharge,by using SFA-Malmquist and other methods,the efficiency of waste resource utilization,environmental total factor productivity and other indexes have been defined and the utilization efficiency and trend of pig breeding waste in China from 2006 to 2017 have been analyzed.The research shows that China’s pig breeding industry is still a“capital investment”industry;the efficient utilization of waste resources and appropriate large-scale breeding are the key to the green growth of pig breeding economy.Under the constraints of environmental protection,the growth of environmental total factor productivity of the pig breeding has slowed down,and its growth is characterized by scale heterogeneity,time-variation and regional differences.The main driving factors of environmental total factor productivity are different on different scales.Technical efficiency is inversely related to technological progress.Medium-scale breeding has growth potential while the growth advantage of large-scale breeding declines significantly.The green development of China’s pig breeding industry must take into account the utilization efficiency of waste resources and the efficiency of breeding technology,and meanwhile pay attention to the advantages of different scales of breeding in different areas.
