基于信息熵模型的建设监理企业城市分布研究

将建设监理企业纳入生产性服务业的城市分布研究框架，引入信息熵理论构建了可分别测度企业城市群分布（M分布）空间特征与城市行政体系分布（R 分布）等级特征的时变模型，并以建设监理 100 强企业为例加以实证检验与分析。研究表明:100 强企业向更高行政等级城市集中分布的趋势明显且具有波动性，而其在东、中、西部城市群间的空间分布则相对均衡且稳定。自 2011 年起，100 强企业城市分布的空间特征和等级特征关系由拮抗转变为协调。

Urban Distributions of Construction Supervision EnterprisesBased on Information Entropy Model

This study allocates construction supervision enterprises（CSEs）into the urban distributions research framework ofproductive services. The information entropy theories are employed to establish time series models for M distribution system and Rdistribution system, which can show spatial and hierarchical characteristics of the CSEs on metropolitan agglomerations and nationaladministrative cities, respectively. Moreover，the models are empirically tested and analyzed based on the data of top 100 CSEs. Theresults indicate that the top 100 CSEs are apt to cluster in cities with higher administrative rank but with fluctuations. On the otherhand，the spatial characteristics of top 100 CSEs in east, central, and west metropolitan agglomerations are relative balanced andstable. The relationship between spatial characteristics of top 100 CSEs and its hierarchical characteristic is changed fromantagonism to coordination since 2011.
