本文讨论了项目分析中的基本问题，并展示了如何在可计算一般均衡（CGE）框架中解决这些问题。探讨了边境价格和部门间联系的作用。CGE框架相比，不太全面的框架，包括效益-成本分析，投入-产出模型，多市场模型，以及基于社会核算矩阵（SAM）的模型。一个说明性的CGE模型的南部部分的圣华金河谷的构建和用于寻找减少水投入的影响，总谷国内生产总值（GDP）和部门产出，就业和土地利用。该模型还被用来确定水的需求曲线的南部部分的山谷，给定的替代规格的生产技术。
This paper discusses basic issues in project analysis and shows how these issues can be resolved in a computable general equilibrium (CGE) framework. The role of border prices and intersectoral linkages is explored. The CGE framework is compared to less comprehensive frameworks, including benefit-cost analysis, input-output models, multi-market models, and models based on social accounting matrices (SAMs). An illustrative CGE model of the southern portion of the San Joaquin Valley is constructed and is used to find the effects of reducing water inputs on aggregate Valley gross domestic product (GDP) and on sectoral output, employment, and land use. The model is also used to determine demand curves for water by the southern portion of the Valley, given alternative specifications of production technology.
