Land Use with Heterogeneous Land Quality: An Application of an Area Base Model
提出异质性土地面积基础模型，应用于美国东南部五州区域，发现土地质量是土地利用的重要决定因素，表明同质性模型存在遗漏变量问题，并采用修正的多项逻辑模型估计参数。
Abstract Area base models are being used in resource assessments to project the availability of farm and forest land. In this paper we introduce a heterogenous land area base model and apply it to a five‐state region in the southeastern United States. Land quality turns out to be an important determinant of land use, suggesting that existing homogeneous land area base models may have an omitted variable problem. Parameter estimates are obtained using a modified multinomial logit model, which allows for error due to the use of county averages and error resulting from the use of sample estimates of land use acreage.
