摘要
农业经济学是一门研究农业和农村发展的应用学科,其研究重点和研究方法也随着社会经济发展的需求而扩展。本文分析了国际农业经济研究的主要领域和前沿方法,探讨了我国未来农业经济研究的发展趋势。国际农业经济研究主要包括:(1)农业生产、市场和政策;(2)资源与环境经济政策;(3)发展经济;(4)农商与食物经济,但这些领域之间又相互交叉融合。从研究方法来看,建立定量化的理论模型,并运用计量经济学进行实证检验,已经成为农业经济研究中被普遍接受的规范研究方法。理论模型设定和政策事前评估主要借助数学优化模型,而实证检验和政策事后评估主要依靠计量经济模型。随着信息获取技术的发展,机器学习理论和非参数计量经济学在农业经济研究中的应用也将日趋广泛。
Agricultural economics is an applied discipline that studies agriculture and rural development.The research focus and research methods of agricultural ecnomics expand with the needs of social and economic development.This paper analyzes the main fields and cutting-edge methods of international agricultural economic research,and explores the potential directions of future development of agricultural economics in China.Based on litearture reviews,it shows that the key research areas of international agricultural economics mainly include:( 1) agricultural production,markets and policies;( 2) economics and policies of resources and environment;( 3) rural development;( 4) agricultural business and food economy,but there is not a clear cut in those areas.From the perspective of research methods,establishing theoretical model and then use econometrics or other quantitative models for empirical testing have become the accepted normative methods in agricultural economic research.The establishment of theoretical model and Ex ante assessment of policy effect are mainly based on mathematical optimization models,while empirical testing and post-evaluation of policy effect are mainly based on econometric models.With the development of information acquisition technology,the application of machine learning theory and non-parametric econometrics in agricultural economy research will also become increasingly widespread.
