| It is a general law of industrialization and socio-economic development in various countries to shift from agriculture to industry.In the strategy of supporting agricultural development in China,industry feeding back agriculture is the fundamental strategy of adjusting the dual economic structure of urban and rural areas,and an important measure to ensure the balanced development of industry and agriculture.At present,there are various ways of back-feeding in China,such as price compensation,low-interest benefiting agricultural loans,etc.,which directly or indirectly compensate the main body of agricultural production and operation.However,the scale of subsidies in China is limited and the ability of subsidies is not strong.The lack of effective return mechanism weakens the policy effect and the function of economic and social benefits.The report of the Nineteenth National Congress emphasizes that the construction of ecological civilization is a millennium plan for the sustainable development of the Chinese nation.At present,environmental problems are prominent,especially in the industrial production process,which is often accompanied by serious environmental pollution.The environmental pollution caused by it is also the main component of China’s environmental problems.Under the background of advocating green development,environmental problems can not be ignored.On the other hand,the employment problem should not be neglected.In this year’s Government Work Report,for the first time,the employment priority policy was placed at the macro-policy level,and the "stable employment" was placed at the top of the "six stable"in order to strengthen the guidance of attaching importance to employment and supporting employment in all aspectsBased on the perspective of agricultural subsidies,this paper analyses the short-term and long-term effects of agricultural subsidies on the environment and unemployment in the process of industry feeding back agriculture.In this model,the tax source of agricultural subsidy comes from taxing the industrial sector which produces environmental pollution,and this part of the tax is used to subsidize the production of the agricultural sector.In this tax transfer mechanism,from the point of view of the enlargement and development of social and economic scale,taxing the industrial sector that produces environmental pollution will reduce the capital retention of the industrial sector that produces environmental pollution,weaken the investment capacity of the sector,and reduce the investment scale and production of the sector to a certain extent,reduce the employment of workers and alleviate the industrial counterpart.Environmental pollution.However,in this process,it is worth noting that subsidies to the agricultural sector support the development of the agricultural sector and increase the income of the agricultural sector.Increasing the income of the agricultural sector will lead to an increase in the demand and consumption of products in the industrial sector,thus stimulating the expansion of the industrial sector,increasing the employment of workers,and the expansion of the production scale will aggravate environmental pollution.Therefore,in this process,whether the results reduce environmental pollution or increase environmental pollution,increase the unemployment rate or reduce the unemployment rate,can not be obtained by simple qualitative analysis,need further analysisOn the basis of Harris-Todaro theoretical model,this paper introduces Copland and Taylor’s environmental quality function to further improve Harris-Todaro model,establishes two-sector general equilibrium model including industrial sector and agricultural sector,and carries out short-term and long-term comparative static analysis with wage subsidy,interest rate subsidy and price subsidy.On the basis of the theoretical model,the parameters in the model are assigned and verified by numerical simulation.The main conclusions of this paper are as follows:1.In the short term,wage subsidy,interest subsidy and price subsidy will not affect the environmental quality.2.In the short run,wage subsidy reduces the urban unemployment rate,while price subsidy increases the urban unemployment rate 3.In the long run,price subsidies improve the environment,while wage subsidies and interest subsidies worsen environmental pollution.4.In the long run,wage subsidy and interest subsidy have reduced urban unemployment rate,while price subsidy has increased urban unemployment rate.Such a conclusion has important practical significance for the implementation of agricultural subsidy policy in the future.From the perspective of the design of economic policy system,any single subsidy policy can not achieve the best of both worlds.Instead,according to the actual situation of the locality,a reasonable mix of wages,interest and price subsidy should be made.Therefore,various subsidy policies should be coordinated in order to give consideration to the environment and employment.Question.In the future research,it is an important direction to study the proportion of various subsidies. |
