本文基于 Chambers 和 Just (1989) 引入的联合多输出技术表示，开发了农业土地利用和生产的空间分解结构计量经济模型。从农场利润函数的灵活规范出发，我们在一个联合且理论上一致的框架中推导出土地利用分配、投入应用、作物产量和牲畜强度方程。为了解释微观数据中审查观测值的存在，该模型通过准最大似然估计为二极限托比特方程组。我们使用覆盖整个英格兰和威尔士的精细空间数据提出了实证应用，其中包括过去四十年土地利用变化的主要经济、政策和环境驱动因素。对扩散污染减排措施效果的模拟说明了我们的方法如何应用于农业环境政策评估。版权所有 2011，牛津大学出版社。
This paper develops a spatially disaggregated, structural econometric model of agricultural land use and production based on the joint multi-output technology representation introduced by Chambers and Just (1989) . Starting from a flexible specification of the farm profit function, we derive land use allocation, input application, crop yield, and livestock intensity equations in a joint and theoretically consistent framework. To account for the presence of censored observations in micro-level data, the model is estimated as a system of two-limit Tobit equations via quasi-maximum likelihood. We present an empirical application using fine-scale spatial data covering the entirety of England and Wales and including the main economic, policy, and environmental drivers of land use change in the past forty years. A simulation of the effects of diffuse pollution reduction measures illustrates how our approach can be applied for agro-environmental policy appraisal. Copyright 2011, Oxford University Press.
