ON THE SOLUTION OF SPATIAL EQUILIBRIUM MODELS*
利用MINOS/AUGMENTED软件包求解两个高度非线性的空间模型，展示模型解并讨论计算经验，对政策与理论研究有参考价值。
ABSTRACT Recent advances in mathematical programming methods and computing technology have the potential for overcoming the many formidable barriers to the widespread solution of nonlinear spatial models. In particular, the recent public availability of the software package MINOS/AUGMENTED has major implications for both policy and theoretical research involving spatial models. In this paper, mathematical programming formulations of two highly nonlinear spatial models are provided, model solutions presented, and associated computational experience discussed. In addition, related work is discussed briefly and suggestions are advanced concerning the potential role of the package in furthering the objectives of this related work.
