农业经济学是作为一门经验式的科学而建立起来的,其地位、可信性及其解决实际问题的能力都决定于这门经验式的科学的本身能力大小,也与社会的需求相关联。无论从这门学科的发展历史和维护农业经济学家的声誉两方面看,我们的研究工作都必须注重以下几方面:(1)理论(包括其它非经济学科)。(2)统计学及其它数量分析技术。(3)证据材料。不能忽视以上任何一方面,它们是支持这门科学的三条腿,缺一不可。但是,我认为现在的研究人员过分热衷和注重理论和统计方法而忽视证据材料,实际上,我们这样做正在削弱这门经验科学的基础地位,也降低了作为一名科研人员的研究水平。认定一项探索性研究成果是否成为一门科学,要看其基础证据以及由此建设起来的理论体系是否站得住脚。经验性的科学依赖于具有与经验证据互为因果的理论论证(更恰当地说,它不是一种反证)。证据材料系统要围绕所阐述的概念而建立,使证据与概念的闸述互为因果。支持或否定某个理论,所应用的证据材料必须与其相吻合。为使这种经验性的验证有根据,在验证过程中要面对被验证的问题,做到合乎逻辑、前后一致, Agricultural economics is established as an empirical science, its status, credibility and its ability to solve practical problems are determined by the size of this empirical science itself, but also with the needs of society . In terms of both the history of the discipline's development and the reputation of preserving agricultural economists, our work must focus on the following aspects: (1) Theories (including other non-economic disciplines). (2) Statistics and other quantitative analysis techniques. (3) Evidence. We can not ignore any of the above. They are the three legs that support this science. However, I think the current researchers are too keen and focused on theoretical and statistical methods to ignore the evidence. In fact, doing so weakened the foundation of this empirical science and lowered the level of research as a researcher. To determine whether an exploratory research achievement becomes a science depends on whether its basic evidence and the theoretical system it builds are viable. Empirical science relies on theoretical arguments that have a causal link to empirical evidence (more properly, it is not an anti-card argument). Evidence materials systems are built around the concepts that are elaborated to make evidence and conceptual discourse a causal link. Support or deny a theory, the evidence used must be consistent with it. To make this empirical verification based on the verification process to be validated issues, be logical, consistent,
