### Evaluation Index System Construction
#### 3.1.2 Evaluation Index Construction  
When determining evaluation criteria and selecting of evaluation indexes, multiple aspects of indexes need to be considered, such as cash flow, logistics, business flow, and information flow. When coordinating fresh agricultural produce supply chain platforms, the mutual influences between different criteria, and the influential relationship between different criteria and development goals should also be considered. The establishment of a set of complete, scientific, and standardized index systems is a prerequisite for the effective evaluation of the service quality of fresh agricultural produce supply chain platforms. The evaluation index system is based on the four aspects of supply chain coordination: logistics, business flow, information flow, and capital flow. These are combined with the characteristics and requirements of fresh agricultural produce supply chain platform services, and the evaluation index system also consists of a series of indexes used to measure the quality of fresh agricultural produce supply chain platform services. The service quality of a fresh agricultural produce supply chain platform comprises a large amount of data. In the analysis and construction of indexes, in this paper, the SERVQUAL service quality model was used to conduct an in-depth analysis, via an evaluation, of fresh agricultural produce supply chain platforms with regard service quality. The evaluation considered both the performance assessment objectives of the supply chain service quality results and its processes. On the one hand, the research focused on assessing the quality of the fresh agricultural produce supply chain platform's services, which was achieved through an examination of the results of the platform's performance. On the other hand, it focused on assessing the current operation status and capability of the fresh agricultural produce supply chain platform, which was achieved through an examination of the platform's process performance. The final result was returned to the business in charge of the platform. This paper not only demonstrated the process of the post-event assessment and the whole assessment system, but it also considered the fresh agricultural produce supply chain platform's long-term development. The selection of evaluation indexes was achieved using Delphi, correlation analysis, and discriminant analysis. First, based on the analysis of the relevant research literature regarding the coordinated evaluation of fresh agricultural produce supply chain platforms and service quality, the relevant indexes with a high frequency of use were summarized. They focused on the integrated supply-chain-related index system, the LSQ measurement model, the SERVQUAL service quality model proposed by [PERSON] et al., and the latest policy issued by the Ministry of Finance and the Ministry of Commerce in the first half of 2021, entitled \"Performance evaluation index system\" in the \"Notice on further strengthening the construction of agricultural supply chain system\" [40; 41; 42]. Combining the basic content of the index system, the framework system for the evaluation of the service quality of the fresh agricultural produce supply chain platform, based on the coordination of the four dimensions, was formed by modifying, adding, deleting, and redefining the corresponding dimensions. Then, the indexes were specifically analyzed to avoid information overlapping between different indexes. This paper used the Delphi method to issue questionnaires to seven experts in the fresh agricultural produce supply chain platform field, and in service quality evaluations, among other fields. After three rounds of questionnaires, integration, and analysis, we organized the experts' opinions and then merged, modified, and deleted some evaluation indexes to obtain a unified and effective evaluation index system. We also deleted indexes with relatively poor discriminative power on the basis of established index systems.
