Abstract:In order to accelerate the realization of the "dual carbon" goal and promote the green and low-carbon development of the express industry, this paper takes the national green and low-carbon development policy document as the research sample, comprehensively uses the text attribute, content analysis and PMC index model, summarizes the green and low-carbon development process of the express industry, summarizes the current policy characteristics and completes the supporting evaluation. The study points out that the policy support for green and low-carbon development of Chinese express has experienced three stages: the exploratory period, the initial period and the formation period of the strategic system. The existing policy system is comprehensive and scientific, but there are problems such as uneven distribution of policy instruments, insufficient binding and mandatory policies, lack of a strong coordination mechanism, and lack of a clear mechanism for measuring, reporting and verifying carbon emissions in the postal sector. Based on the above characteristics and problems, it is suggested to establish a strong communication and coordination mechanism, increase the proportion of mandatory policies, and increase the supply of policy tools at the demand side.
