Industrial assistance is one of the most important parts of targeted poverty alleviation, the impact of poverty identification and targeted assistance on the efficiency of poverty alleviation industry is worth of further study. Based on the survey data of 534 farmers in Shizhu Tujia Autonomous county, Chongqing, this paper applied the classical statistical analysis framework to test the differences in planting industry efficiency between villages and farmers after poverty identification, and further explored the formation of differences. The results show that: (1) Poverty identification and targeted assistance significantly promote the efficiency of the planting industry, especially in the poverty-stricken villages and the poor households. (2) The policy is the key factor that causes significant differences in planting efficiency between poor and non-poor villages and households. Among them, infrastructure construction such as road construction, and characteristic planting industries have a particularly strong impact on poverty-stricken villages and poor households. (3) The effect of age on the efficiency of the planting industry in poverty-stricken areas shows a "U-shaped" pattern, in which 55 to 60 years old is an efficiency turning point. (4) Farmers with high school education and above can promote the efficiency of the planting industry. Therefore, in order to resolve the unbalanced contradictory problem, the local governments should continue to implement industrial assistance policies and establish a long-term mechanism to ensure the steady growth of poor people's income, and improve the agricultural labor force in poverty-stricken areas, as well as increase the level of human capital.
