Combined with the realistic background of the impact of African swine fever on China's pig breeding industry,this paper uses the large sample sub-regional sampling survey data nationwide,starts from the two attributes of policy tools and intervention objects,and makes necessary considerations on the rationality of support policies for large-scale pig breeding through the ex-ante attitudes of large-scale farmers.The results showed that after the outbreak of a major epidemic,the large-scale farmers were willing to accept the support policy before the actual support policy,and the large-scale farmers who were willing to accept the support policy actually received the support policy,then the large-scale pig breeding support policy was reasonable.For large-scale pig farmers,they are willing to accept direct support policies if they think that the previous large-scale pig breeding support policies are more transparent or fair.It is believed that the previous large-scale pig breeding support policy is more transparent,and the government will agree with the market-oriented action of the pig breeding industry.For medium-scale farmers,they are willing to accept direct support policies if they agree with the government's planning of pig breeding industry.It is believed that the previous large-scale pig breeding support policies are more transparent,and by strengthening the recognition of the government's planning actions for the pig breeding industry,they are reluctant to accept direct support policies.
