信用度是衡量市场主体信用等级的重要指标,它是政府监管和建设市场主体从业的重要依据。由于我国现行的建设市场信用度评价体系还不够成熟,评价标准、评价方法以及数据采集等的科学性与合理性等方面存在不足,如何检验政府部门公布的建设市场主体信用度和建设市场主体信用度评价体系是目前亟待解决的问题。本文根据中心极限定理,提供对A地区政府公布的房建类企业、市政类企业、园林类企业以及装饰类企业等四类市场主体的信用度进行检验,进而判断政府公布的四类企业的信用度的科学性与合理性,同时也对评价标准、评价方法、数据采集等的科学性和合理性等进行检验,并据此提出相关建议。本文的研究成果对于政府公布建设市场主体的信用等级具有重要意义。

Credit is an important index for measuring the credit level of market subjects. It is an important basis for government supervision and construction market subjects. Because the building of credit evaluation system for the Chinese construction market is late, the current credit evaluation system is not yet mature, and there are also deficiencies in the evaluation criteria and the evaluation methods. Therefore, how to test the credit data the government publishes and the evaluation system for the Chinese construction market is a urgent problem to solve.Based on the Central Limit Theorem, we test the credit data of the construction market subjects issued by the government of A region. And then we can judge the scientificness and rationality of the credit data issued by the government. We can also test the correctness of the evaluation criteria and the evaluation methods indirectly,make some suggestions about the credit system according to the conclusions. The research results of this paper are of great significance for the government to announce the credit rating of the market subjects.
