Agricultural Economics as a Poster Child of Applied Economics: Big Data & Big Issues1
回顾农业经济学如何长期体现应用经济学精神，强调数据与理论共同演进的重要性，并指出未来研究需整合农业、能源与环境，分析生物经济与信息技术的融合。
Abstract Agricultural economists have embodied the notions of applied economics for a long time. They have used economic principles to address real‐world problems, integrating economics and scientific knowledge. Applied economics tends to be multidisciplinary and develop applied concepts, theories, and tools. Some, like human capital, diffusion of innovation, contingent valuation, and numerous numerical and econometric techniques have spread throughout economics. Agricultural economic research has been data intensive, and improved information technologies strengthen this tendency. Yet data without theory is of limited use and coevolution of theory and data are essential. Empirical analysis should incorporate quantitative information as well as narratives. We are challenged to understand the coevolution of business, supply chains, and technology, and how they are affected by policies and affect markets. Research should integrate agriculture, energy, and the environment and develop tools to analyze and regulate the emerging bio‐economy integrating biotech and infotech.
