随着电子商务的发展，大宗商品电子交易市场成为我国经济发展不可或缺的部分。近年来由于不良企业主体随意准入大宗市场而引发的风险事件频发，且呈现高隐蔽、难发现的趋势特征。现有交易平台间缺乏有效的关联协作，平台内缺乏面向交易过程的动态反馈，数据缺乏融合共享，导致市场主体跨平台行为、跨交易行为关联分析能力弱，系统性评估主体准入资格的能力欠缺，而且现阶段国内外对准入资格评估方面的理论技术研究相对缺乏。因此，亟需针对主体准入资格研究在线评估技术，为市场提供主体准入资格评估服务。
首先，论文对国内外现状与发展趋势进行了总结分析，然后针对市场准入规则不统一，评估数据片面单一、平台缺乏关联协作等问题，分别提出了准入资格评估的一个方法和两种机制，分别是基于规则的个性化准入资格评估方法、基于交易异常监测结果的动态反馈机制、基于跨平台评估结果的网络关联共享机制。
其次，基于多源数据融合对指标数据进行规范统一，形成了准入资格评估指标集，并以每个指标数据的价值取向和层级关系进行分类和分级，构建了准入资格评估指标体系。在此基础上，结合层次分析法建立了三层层次结构评估模型，设计了详细的评估流程和具体的计算方式，并对模型进行实例验证分析。实验结果表明，该模型能够对市场不同情况的主体进行评估计算，得到合理评估结果。
最后，论文依据市场需求调研分析，对系统进行总体设计、业务功能设计、数据库设计，并基于 Java 平台的开源框架 Spring Boot 实现了一套面向大宗商品交易市场的企业准入资格查验评估系统。经部署测试，该系统能够在入市前对企业主体进行查验评估，为市场提供在线评估、高效反馈、信息可靠的主体准入资格评估服务，具有一定的社会经济价值贡献。该系统已在国家重点研发项目综合服务平台上完成集成应用。
论文中建立的理论技术体系能够推动大宗商品电子商务监管与服务领域相关理论技术的研究创新，为解决主体在线准入资格评估的服务难题提供可行方案。论文从服务关键技术研究、综合服务平台实现等方面形成相对完整的理论技术体系，可以促进大宗商品电子交易市场监管与服务的网络化与信息化革新，为解决当今大宗商品电子商务市场的主体准入问题提供了技术保障。

With the development of e-commerce, the electronic trading market of bulk commoditieshas become an indispensable part of my country's economic development. In recent years, the
risk events caused by the random access of non-performing corporate entities to the bulkmarket have occurred frequently, and they have shown a trend of high concealment and difficulty to detect. There is a lack of effective association and collaboration among existing trading platforms, the lack of dynamic feedback for the transaction process within the platform, and the lack of data integration and sharing, resulting in weak correlation analysis
capabilities of market participants' cross-platform behavior and cross-trading behavior, and the ability to systematically evaluate the entry qualifications of entities. In addition, there is a
relative lack of theoretical and technical research on admission qualification assessment at home and abroad at this stage. Therefore, there is an urgent need to study online evaluation
technology for subject access qualifications, and to provide subject access qualification evaluation services for the market.
First of all, the paper summarizes and analyzes the current situation and development trends at home and abroad, and then proposes a method and two mechanisms for access qualification evaluation in response to the problems of non-uniform market access rules, one-sided evaluation data, and lack of association and collaboration on platforms. , which are a rule-based personalized access qualification evaluation method, a dynamic feedback mechanism based on transaction abnormality monitoring results, and a network association sharing mechanism based on cross-platform evaluation results.
Secondly, based on the fusion of multi-source data, the index data is standardized and unified to form an access qualification evaluation index set, and the value orientation and hierarchical relationship of each index data are classified and graded, and an access qualification evaluation index system is constructed. On this basis, combined with AHP, a three-layer hierarchical structure evaluation model is established, and a detailed evaluation
process and specific calculation method are designed, and the model is verified and analyzed by an example. The experimental results show that the model can evaluate and calculate the
subjects of different market conditions, and obtain reasonable evaluation results.
Finally, according to the research and analysis of market demand, the thesis carries out the overall design, business function design and database design of the system, and implements a set of enterprise access qualification inspection and evaluation system oriented to the commodity trading market based on the open source framework Spring Boot of the Java platform. After deployment and testing, the system can inspect and evaluate enterprise entities before entering the market, and provide the market with online evaluation, efficient feedback, and reliable information for entity access qualification assessment services, with certain social and economic value contributions. The system has been integrated and applied on the comprehensive service platform of national key R&D projects.
The theoretical and technical system established in the paper can promote the research and innovation of related theoretical technologies in the field of commodity e-commerce supervision and service, and provide a feasible solution for  solvingthe service problem of online access qualification evaluation of subjects. This paper forms a relatively complete theoretical and technical system from the research of key service technologies and the realization of comprehensive service platform, which can promote the network and information innovation of the supervision and service of the electronic trading market of bulk commodities, and solve the main standards of the electronic commerce market of bulk
commodities. The entry problem provides technical support.
