Research On Subsidy Policy Instrument Effect To Animal Manure Treatment Methods

With the development of livestock and poultry breeding industry in Shaanxi Province,the pollution problem of livestock has become increasingly serious.Pollution of livestock and poultry farming has jeopardized the living environment of rural residents and has become an important source of pollution for rural living environment,thus become an obstacle to sustainable development.The resource utilization of livestock and poultry waste could be related to the effective supply of livestock and poultry products.This utilization could relieve the environmental pressure caused by livestock and poultry excrement and improve the living environment of rural residents,which is a major livelihood project.The government has adopted a subsidy policy to encourage farmers to control the pollution of livestock and poultry.To understand the current status of implementation of policies,this research study the behavior of farmers from a micro perspective,which could be the reference for further optimization of policies.At first,this study introduces the background of the problem and reviews the relevant research at China and foreign countries.Then,this study defines large-scale livestock and poultry breeding industry,introduces the main pollution treatment technologies and the theoretical basis of environmental pollution problems.Then demonstrate theoretical basis and feasibility of the policy tools.Afterward,the pollution of the country and Shaanxi province was estimated and the related subsidy policies were listed.Through the actual survey data,this paper analyzes the influencing factors of adopting biogas technology in large-scale farms in central Shaanxi plain with the binary Logit model.This study found the attitudes of farmers,whether the alternative choice of biogas technology was profitable,and whether subsidies were obtained had a significant impact on the adoption of biogas technology by farmers.At end,based on the above theoretical research and empirical research,conclusions are drawn,and proposals for improving the current subsidy policies for large-scale farms are put forward.This study has made some conclusions.The environmental pollution caused by large-scale livestock and poultry breeding industry has externalities.Under the premise that the aquaculture industry is a meager profit industry,the introduction cost of pollution control facilities is unwilling to bear for most farmers,therefore,the government must adopt incentive policies and regulatory policies.This study found that the subsidy policy is effective in controlling pollution of livestock and poultry breeding industry.Under the current level of pollution and governance,the government needs to increase the amount of subsidy and enrich the subsidy methods.The more flexible method is more practical and effective.The farmers don't have scientific and accurate understanding of livestock and poultry breeding pollution.Unscientific cognition leads to negative attitudes.The government's supervision over farmers is insufficient.A considerable proportion of small-scale farmers lack supervision.The protection of the environment is positively related to the work.Therefore,supervision and publicity of farmers are also indispensable for controlling pollution of livestock and poultry.After the construction of biogas facilities has been completed,there are major problems in the later period of operation.Biogas equipment cannot be used effectively.The government needs to strengthen the operational investment in the later period.The new findings of this research are psychological cognition variable has a significant negative impact at the same time to demonstration that the subsidy policy has significant impact on the rationality and feasibility of the subsidy policy.The fundamental reason lies in farmers' unscientific understanding of environmental pollution and livestock and poultry.
