摘　　要：基于地价二元构成及供求关系理论,明确了集体建设用地地价不仅受表征土地物化资产价值的个别因素影响和外部经济联系引致的区位级差影响,还因土地供需关系的不同使其在行政村之间存在整体等别差异,提出以行政村、均质网格为基本单元分别评定的土地等和级指数为自变量,以个别因素条件统一的样本地价为因变量,构建区域整体的基准地价二元关系模型,并基于模拟退火思想设计了模型回归拟合与动态优化的抽样回放统计方法,以合浦县的集体商服用地基准地价评估应用进行了实例验证。研究有效克服了因集体建设用地及其交易案例离散分布带来的抽样稀疏现实问题,模型优化、结果合理。This paper first explains that land price of collective construction land is affected by individual features reflecting the value of materialized assets on the land,land location grades resulting from external economic links,and supply-demand relationship of land in the village according to the land value's dualism and supply-demand theory.This paper puts forward a model to predict the benchmark land price by relationship between the dependent variable of land price and two independent variables of indexes of land classes and land grades.The dependent variable is surveyed by sampling,the former independent variable is calculated by the grade index ofits adjacent basic grid,and the latter is from the class index of village by overlaying.A statistical method of sampling with replacement for regressing and optimizing the model is realized by simulated annealing algorithm.The approach is applied in the case on appraising benchmark land price of collective construction business land in Hepu county.The research overcomes the statistical problems due to insufficient samples,and is verified by optimized model and reasonableresults.
