养殖型家庭农场适度规模：内在机理、动态优化及系统绩效

To ensure the sustainable development of family farms, we must classify the management according to the business contents and optimize the proper scale of operation. The lack of pertinence, systematicness and integrity of the modest scale of family farms in the past is hard to implement. Therefore, this project uses agricultural economic management theory and system dynamics method to investigate the internal mechanism, dynamic optimization and system performance of the moderation scale of farmed farms by questionnaires and field surveys. The project uses system dynamics, game theory and econometrics methods to build a modest scale system model for farmed farms from three aspects of production, ecology and policy control, and repeatedly adjust the level of environmental protection technology and equipment, preferential taxation policies, subsidies and supervision The dynamic simulation of the system is carried out according to the degree of accountability, the TOPSIS method is used to evaluate and compare the output results (performance value) by multiple attributes to find the optimal match between the appropriate scale and system performance. There are three innovations in this project: Farm and three subsystems to build the starting point of innovation; the use of systems engineering methods to carry out theoretical research and empirical analysis of the problem and a variety of integrated mathematical methods to build mathematical models; from a moderate scale perspective on the performance of multi-attribute evaluation. The results can provide support and reference for the healthy development of farmed farm.

要保障家庭农场可持续发展，必须根据经营内容进行分类管理并优化其适度经营规模。以往的家庭农场适度规模缺乏针对性、系统性和整体性，难以实施。因此，本项目采用农业经济管理理论和系统动力学方法，通过问卷调查和实地调研等，研究养殖型家庭农场适度规模的内在机理、动态优化及系统绩效。项目运用系统动力学、博弈论及计量经济学方法从生产、生态及政策调控等三个方面构建养殖型家庭农场适度规模系统模型；反复调整环境保护技术设备水平、税收优惠政策、补贴力度和监管问责力度等对系统进行动态模拟仿真；运用TOPSIS方法对输出结果（绩效值）进行多属性评价和比较，找到适度规模与系统绩效的最优匹配；本项目研究有三个创新：针对养殖型家庭农场并由三个子系统构建的切入点创新；运用系统工程方法对该问题进行理论研究及实证分析且综合多种方法构建数学模型；从适度规模角度对系统绩效进行多属性评价。成果可为养殖型家庭农场健康发展提供支持和参考。
