Livestock and poultry breeding pollution is a kind of typical agricultural non-point source pollution. It is increasingly not allowed to ignore in China the heavy environmental load with a rapid growth in industry of livestock and poultry breeding. But China has a weak ability to control its livestock and poultry breeding pollution at present, for its whole defective environment management system and ambiguous even ineffective environmental policies, laws and regulations, especially paying less attention to the behavior of livestock and poultry farmers. Although environmental protection system of economic compensation has been an efficient path for the world to explore to solve the environmental crisis in the process of development and many scholars have also emphasized the necessity of taking economic means to control pollution, in the field of livestock and poultry breeding pollution regulation, China’s theory researchers and policy designers failed to accurately grasp the relationship between industry scale change and environmental protection effect, and could not know clearly the degree of livestock and poultry farmers’willingness of green subsidy for waste disposal and the corresponding change of their adopt behaviors of waste disposal. To this end, this paper systematically explores the green subsidy policy of livestock and poultry breeding pollution regulation, in order to give out a scientific design idea in an overall view for environment economic policy. With a certain reference and enlightenment, the research in the paper makes for China’s agricultural subsidy policy to enrich its content and adjust its direction, further, will help the government correctly guide livestock and poultry farmers’ environmental protection behaviors in their production, unified economic and environmental benefits to achieve the sustainable development of livestock and poultry breeding industry.After searching the literature and collecting yearbook data, the paper designs a questionnaire and takes a form of face to face interview for field data collection from 608 pig farmers in Xinfeng Town as a plain terrain sample, Shangtian Town as a plain with hilly terrain sample, and Hunan Town as a hilly terrain sample, Zhejiang Province, in order to study the livestock and poultry farmers’ two willingness for waste disposal in their production to be decided, respectively, the green subsidy willingness under the established breeding mode and the behaviors change willingness under the supposed implementation of the green subsidy. On this basis, the paper gives out a design for the green subsidy of livestock and poultry breeding pollution regulation. The main content of the paper include followings. Firstly, clearing the meaning of the externalities of livestock and poultry breeding pollution treatment technology, the paper gives theoretically out an interpretation of social marginal cost and then analyzes environment economic characteristics for livestock and poultry breeding; with an induction and summarization of livestock and poultry breeding pollution control policy all over the world, explains the effect and scope of application respectively for technical specification policy, administrative regulation policy, and environmental economic policy (including restrictive and incentive measures); further, discusses the changes of livestock and poultry farmers’ adoption behaviors of waste disposal under different governance policy intervention. Secondly, combining with the development course and the present situation of China’s livestock and poultry breeding industry, the paper calculates the environment load composite index of livestock and poultry breeding industry to evaluate the bearing capacity of livestock and poultry breeding environment, using the time-series data of Zhejiang Province during 1978-2012; then predicts the bearing capacity of livestock and poultry breeding environment under "zero solution" by the model of GM (1,1); further, builds a model based on the experience of a theory of system science to analyze the dynamic coupling of environment load with economy growth in the industry of livestock and poultry breeding so that the trend of the dynamic coupling of environment load with economy growth is calculated in the industry of livestock and poultry breeding under "zero solution" in Zhejiang Province. Thirdly, the paper designs a questionnaire by CVM and takes a form of face to face interview to look for the livestock and poultry farmers’green subsidy willingness for waste disposal in their production under the established breeding mode, then finds out the significant factors of that the livestock and poultry farmers respond to the policy of green subsidy through a binary Logit model and those of their green subsidy willingness decided through a multiple quantitative regression model, in order to define theoretically the limits for the policy of ban and restriction and clear identify the premise for the policy of green subsidy. Fourthly, with the questionnaire results on the adoption behaviors of waste disposal, the paper finds out the significant factors of the livestock and poultry farmers’ adoption behaviors of waste disposal under the current situation through a disorderly classification Logit model and those of their behaviors change willingness for waste disposal under the supposed implementation of the policy of green subsidy through a Probit model, in order to clarify theoretically the mechanism of the effect of the policy of green subsidy acting on the livestock and poultry farmers’behaviors change willingness for waste disposal. Lastly, with the practical experience at home and abroad for reference and the theory basis put forward, the paper based on the above empirical research gives out a design for the green subsidy of livestock and poultry breeding pollution regulation from five aspects of overall framework, price stability mechanism, content of policy, implementation procedures, and supporting measures.The main ideas from the results of the study in the paper are listed as follows. The first, livestock and poultry breeding industry is faced with the severe environment pressure in the long-term development, so it is imperative to regulate livestock and poultry breeding pollution. Compared with technical specification policy, administrative regulation policy, and restrictive measures in environmental economic policy, Pigou’s environmental subsidy can guide adequately the livestock and poultry breeding farmers for a conscious pollution treatment, avoiding well the problems on the technical operation level of policy, so as to change "end treatment" into "source control". The second, the implementation of the policy of green subsidy for waste disposal is beneficial to meet the livestock and poultry farmers’ reasonable demand of production expansion, but the price fluctuation of animal products is the most important reason for the policy failure. Due to the production benefit motivation is the premise of environmental protection incentive, before the implementation of the policy of green subsidy for waste disposal, the government must maintain a stable price of animal products so as to ensure reasonable income of the livestock and poultry farmers. The third, the effect of the policy of green subsidy for waste disposal is influenced by the price fluctuation of animal products, finally to act on the livestock and poultry farmers’ behaviors change willingness for waste disposal through the alteration of social optimal production scale. In the empirical research on pig-breeding of the paper, the factors such as family’s annual income, knowledge of waste reduction methods, willingness of waste disposal training, shortest distance between piggeries and farmlands, and number of waste disposal technology service stations, receive a obvious impact come from the price fluctuation of animal products, in turn to affect the effect of the policy of green subsidy for waste disposal; the factors such as evaluation of net income of waste disposal, knowledge of the policy of ban and restriction, shortest distance between piggeries and rivers, hardly impacted by the price fluctuation of animal products, exert influence on the livestock and poultry farmers’ behaviors change willingness for waste disposal. Therefore, when a price fluctuation of animal products happens with the implementation of the policy of green subsidy for waste disposal, the government should devote its efforts to increase pig farmers’ net income of waste disposal, give the environmental reasons for its policy of ban and restrictions more clearly, and remove the piggeries near the rivers, to achieve the target of enhancing the livestock and poultry farmers’ behaviors change willingness for waste disposal. The last, it is a key to determine a guaranteed lowest price for the policy of green subsidy for waste disposal to motivate the livestock and poultry breeding farmers to adopt a conscious pollution treatment. For the government, a mechanism of price stability, not a long-term sustained subsidy, ought to be created to achieve a long-term governance of livestock and poultry breeding pollution, for it can make the livestock and poultry farmers pay more attention to the environmental effect which their waste disposal behaviors bring when they expect to get their reasonable profits, not only for saving fiscal spending through raising guaranteed lowest price of animal products. It is different from the case of other agricultural non-point source pollution caused by pesticides, fertilizers or agricultural film that the waste from livestock and poultry breeding can be disposed in a correct way for "resource utilization" which brings some economic benefits. So the green subsidy for waste disposal should only be an instructive incentive to inspire the livestock and poultry breeding farmers to find out the potential marginal rate of return brought by the waste’s "resource utilization" in a stable price system of animal products. Obviously, the net income of waste disposal at least greater than zero is a necessary condition, and the green subsidy for waste disposal plus the net income of waste disposal at least equal to the loss is a sufficient condition, both for the fact that the green subsidy for waste disposal can produce an incentive effect. With the guaranteed lowest price is determined in the stable price system of animal products, three schemes for consideration are drawn out for the government to adopt combined with the system of fines or (and) the policy of ban and restriction according to the livestock and poultry farmers’green subsidy willingness, namely full subsidy, shared subsidy under price support, and full price support.Compared with the same kind of researches, the paper achieves three advances as follows. Firstly, clearing the meaning of the externalities of livestock and poultry breeding pollution treatment technology, an interpretation of social marginal cost is gives theoretically out so that environment economic characteristics for livestock and poultry breeding is analyzed for a demonstration of the applicability and effectiveness of the policy of green subsidy to livestock and poultry breeding pollution regulation. Secondly, the feasibility of the policy of green subsidy for waste disposal is demonstrated from the perspective of microscopic economic subject requirement, using CVM to look for the livestock and poultry farmers’green subsidy willingness for waste disposal in their production under the established breeding mode. Thirdly, the factor of price fluctuation of animal products is introduced into the design for the green subsidy of livestock and poultry breeding pollution regulation to create a stable price system of animal products, and through the analysis of adjusting guaranteed lowest price, three schemes for consideration are drawn out, namely full subsidy, shared subsidy under price support, and full price support.
