| The ultimate goal of comprehensively implementing the rural revitalization strategy is to achieve common prosperity,which is also the essential requirement of socialism with Chinese characteristics.To promote common prosperity,we should not only start from the material civilization,but also from the spiritual civilization,and constantly improve the happiness of rural residents.Since the reform and opening up,China has made remarkable achievements in economic development and become the world’s second largest economy.However,the happiness index of Chinese people is still at a low level among major countries in the world,which does not match the strength of China’s economy.Our country has achieved comprehensive victory in poverty alleviation,farmers’ income and living standards have improved steadily,but it is undeniable that the gap between urban and rural income and wealth is still large,and the unbalanced and uncoordinated development of urban and rural areas is still prominent.Under the background of rural labor force going out for employment,the problem of rural aging is more and more serious,coupled with the weak characteristics of agriculture,it is relatively difficult to improve farmers’ happiness.Seeking happiness for the people is the original aspiration of the CPC and the core goal of promoting common prosperity in the new era.In this context,focusing on improving the happiness of rural residents and sharing the fruits of rural revitalization are of great significance to consolidating and expanding the achievements of poverty alleviation and realizing common prosperity.Based on the theory of happiness economics,this paper uses the data of China Labor Dynamics Survey(CLDS),OLS model and intermediary effect model to analyze the impact of the adoption of social agricultural machinery services on the well-being of rural residents,and discusses its mechanism and heterogeneity.The following conclusions are reached:(1)64% of rural households choose to adopt socialized agricultural machinery services,and the average happiness of rural residents is 3.12,which is at the medium level and has great room for improvement.The adoption of social agricultural machinery services can help improve the happiness of rural residents.The results are still robust after endogenous transformation model,Heckman two-phase model,core variable test and sample change.(2)From the perspective of mechanism,the socialized service of agricultural machinery improves the happiness of rural residents by promoting non-agricultural employment and training of agricultural production technology,but the socialized service of agricultural machinery does not improve the happiness of rural residents by expanding the operation scale of farmers.(3)Further heterogeneity analysis shows that there is intergenerational heterogeneity in the impact of agricultural machinery socialization service on the well-being of rural residents,which significantly improves the well-being of the older generation of farmers,but has no significant impact on the well-being of the new generation of farmers;It has a significant positive effect on the well-being of farmers in central and western regions,but has no significant effect on the well-being of farmers in eastern regions.Based on the above conclusions,the following three policy suggestions are put forward: first,increase the supply of agricultural machinery socialized service and continuously improve the level of agricultural machinery socialized service;The second is to guide the socialized service supply and demand of agricultural machinery to connect,promote farmers non-agricultural employment;Third,promote the innovation of social agricultural machinery service model,provide differentiated agricultural services for different groups,and continue to promote the happiness of rural residents. |
