| The implementation of the rural revitalization strategy is a major measure to promote the fundamental solution of issues relating to agriculture,rural areas and farmers,which is related to the realization of high-quality development of agriculture and rural areas.In the system of rural revitalization strategy,prosperous industry is the foundation and the prerequisite for rural revitalization,while the integration of three industries is an important grasp and fundamental way to promote prosperous industry.Promoting the integrated development of the three rural industries not only provides new ideas and methods to increase agricultural efficiency and farmers’ income,but also helps to realize the rural revitalization strategy on the ground.Therefore,the study of the impact of the integration of three rural industries on farmers’ income is of great significance for promoting stable income growth of farmers and realizing rural revitalization.Based on theoretical analysis,this thesis provides an in-depth analysis of the impact mechanism of the integration of rural three industries on farmers’ income and puts forward corresponding research hypotheses.Secondly,the evaluation index system of the integration of rural three industries is constructed,measured by the entropy method,and the regional differences and dynamic evolution process of the development of the integration of rural three industries are analyzed by using the Dagum Gini coefficient and kernel density estimation.Once again,the fixed-effects model is constructed to explore the impact of rural tri-product integration on farmers’ income and its heterogeneity;the mediating effect model is established to analyze the mediating effect of the integration of rural three industries on farmers’ income with agricultural price and agricultural labor as the mediating variables;the panel threshold model is established to verify the impact of the integration of rural three industries on farmers’ income under different levels of financial support for agricultural expenditure as the threshold variable.The non-linear effect of the integration of rural three industries on farmers’ income at different levels of fiscal support for agriculture was verified by a panel threshold model.The following conclusions are drawn from the empirical analysis.Firstly,the development level of the integration of rural three industries in all provinces of China has shown a gradual increase,but the gap between the eastern and the central and western regions is obvious,with the largest intra-regional differences in the eastern region,and interregional differences are the main source of differences in rural three-product integration.The absolute differences in the integration of rural three industries within the country and the eastern,central and western regions have expanded,and the relative differences between the country and the central and western regions are also increasing.Second,the integration of rural threeindustries has a positive contribution to farmers’ income,mainly on wage income and business income.There is a heterogeneous effect of the integration of rural three industries on farmers’ income,which is manifested in the greater effect of the development of the integration of rural three-industries on increasing income for those whose income levels are at or below the middle level,the more obvious effect on increasing farmers’ income in the central and western regions,and the stronger effect of the extension and integration of the agricultural industry chain on promoting farmers’ income growth.Third,the integration of rural three industries affects farmers’ income growth through two paths: value-added agricultural products and promotion of agricultural labor migration.There is a partial mediating effect of value-added agricultural products on the integration of the three rural industries and farmers’ income,and the ratio of the mediating effect to the total effect is 9.8%;there is also a partial mediating effect of agricultural labor transfer on the integration of the three rural industries and farmers’ income,and the ratio of the mediating effect to the total effect is 19.4%.Fourth,there is an obvious non-linear threshold feature of the integration of rural three industries on farmers’ income,which is manifested in the fact that the promotion effect of the integration of rural three industries on farmers’ income increases with the increase of financial support expenditure on agriculture.Finally,based on the above research findings,the following suggestions are made to promote the development of the integration of the rural three industries in China to achieve the increase of farmers’ income increase: first,actively explore and promote the rapid development of the integration of the rural three industries;second,apply policies according to categories to consolidate the achievements of the integration of rural three industries to increase income;third,take multiple measures to improve the supporting system of the integration of the three rural industries;fourth,collaborate up and down to strengthen the financial guarantee of the integration of the three rural industries. |
