General Conceptual Approach to Modeling the Livestock Sector: Application to the Japanese Swine-Pork Sector Model with Analysis of the
提出一种通用的畜牧业部门建模概念方法，提供一致的变量设定规则，并以日本猪-猪肉部门为例，分析取消进口门槛价格和可变关税的影响。
Many livestock sector models have limited coverage of relevant variables and are somewhat ad hoc in their structure in the choice of what should be specified as behavioral equations. This study develops a generic conceptual approach to modeling the livestock sector that provides consistent rules of specification and better coverage of variables. The new approach departs significantly from existing models. This approach is applied to modeling the swine-pork sector of Japan and then used to analyze the impact of removing Japan's gate price policy and variable levy for pork imports.
