The rapid development of China′s economy is inseparable from the support of the transportation industry. The transportation industry is a basic and service-oriented industry that involves thousands of households. Especially the implementation of China′s "the Belt and Road initiative" and "Transportation Power" strategy has brought new development opportunities to the transportation industry, the healthy development of the transportation industry is crucial to China′s economic prosperity. In recent years, accidents have occurred frequently in the global transportation industry. Various incidents such as invalid supervision, negligence of duty, and illegal operations are closely related to the corporate social responsibility of the transportation industry. Enterprises are important parts of society. Enterprises must not only create economic benefits, but also bear legal responsibilities to shareholders and employees, as well as to consumers, communities and the environment.

This article is based on authoritative reports such as the International Organization for Standardization ISO26000, the G4 standard of the Global Reporting Initiative and the "13th Five-Year Development Plan for Energy Conservation and Environmental Protection in the Transportation Industry" and other documents related to corporate social responsibility. Eliminate indicators covering duplicate information through principal component analysis and related analysis, establish 7 criteria layers including responsibility governance, community development and economic contribution, and establish 51 indicators including corporate social responsibility department, environment-friendly products and R&D investment corporate social responsibility evaluation index system. In the selection of evaluation methods, only a single evaluation method is adopted for a certain problem, and the results obtained will have different biases and irrational points. Therefore, this paper establishes a circular correction theory to build a corporate social responsibility evaluation model for the transportation industry. Comprehensively consider the common points between various weighted evaluation results to improve the rationality of the evaluation method and the credibility of the results.

Features and innovations of this article: First, the single evaluation method is cyclically revised through the three combined evaluation methods of Mean method, Boarda method and Compeland method, and then the unified ranking of the three combined methods is obtained, thereby overcoming the inherent one-sidedness and persuasion of the single method. Therefore, this article reasonably considers the performance of corporate social responsibility in the transportation industry. Second, before data processing, the consistency of a single evaluation method is judged by Kendall test, after the data is processed, the consistency of the results is tested a second time through the Spearman test. It guarantees the rationality of the combined evaluation results and solves the problem that the data is not convincing when the data is directly combined after a single evaluation. At the same time, the external correlation test is conducted with other evaluation results. The test results show that the cyclically revised evaluation results in this paper have a high external correlation. Third, this article comprehensively analyzes the current status of corporate social responsibility in the transportation industry by typical enterprises, which helps transportation enterprises to objectively locate their own development status and adopt differentiated measures to improve the quality of supervision. The empirical results show that state-owned enterprises and air transportation enterprises in the transportation industry have performed better social responsibility.

This paper analyzes the performance of corporate social responsibility performance in the transportation industry based on the results of the cyclic revision evaluation. This article abandons the simple analysis process of the previous corporate social responsibility evaluation that only lists the results, and focuses on analyzing the common characteristics of the top 10 companies to provide a realistic basis for companies to better implement social responsibility. The empirical results show that the performance of corporate social responsibility in the transportation industry is affected by the nature of the enterprise, industry characteristics and value of the enterprise. Throughout all companies, air transport companies performed best overall; 6 of the top 10 companies were state-owned enterprises; 6 of the top 10 companies were worth more than 100 billion yuan, of which 3 were more than 200 billion yuan. Through the analysis of typical enterprises, it helps transportation enterprises to objectively locate their own development status and take differentiated measures to improve the quality of supervision.
