Abstract: In order to further improve the policy system of China’s live pig industry and promote its development, based on the perspective of policy tools, this study used text quantitative analysis method from two-dimensions（policy instruments types and live pig industry chain） to conduct word frequency analysis and coding analysis on 148 central policy texts of China’s live pig industry from January 2004 to November 2021. The results showed that among the 148 policy documents, the most frequent keyword was “live pig”, which appeared 4 380 times in the 148 policy documents, with a weighted percentage of 2.44%. The keywords “slaughter” “work” “department” “production” “management” “strengthening” “market” and “epidemic” appeared 2 553, 1 668, 1 510, 1 217, 1 072, 1 054, 881 and 828 times, respectively. The weighted percentages were 1.42%, 0.93%, 0.84%, 0.68%, 0.60%, 0.59%, 0.49% and 0.46%, respectively. A total of 1 537 policy instruments were obtained from 148 documents.From the dimension of type of policy instruments, among the 1 537 policy instruments, there were 390 supply policy instruments, accounting for 25.37%. There were 1 120 environmental policy instruments, accounting for 72.87%. There were 27 demand-type policy instruments, accounting for 1.76%.From the dimension of the live pig industry chain, among the 1 537 policy tools, there were 368 policy tools of breeding links of piglets, accounting for 23.94%. There were 411 policy tools of live pig breeding links, accounting for 26.74%. There were 440 policy tools of pig slaughtering and processing links, accounting for 28.63%. There were 318 policy tools of circulation and sales links, accounting for 20.69%. It indicated that the pig slaughtering and processing links were the key link of the pig industry supervision at present, and the government was more inclined to promote the development of the pig industry by regulating the market environment. Finally, the author put forward the following countermeasures and suggestions: improving the infrastructure, complement the short board, strengthening the construction of industry organization and give play to the role of industry, increasing tax incentives to stimulate market vitality, setting planning objectives and providing direction guidance, connecting domestic and international markets to achieve sustainable development, building a service-oriented government and increasing government exchanges with other countries.
