| The continuous concentration management of the land has become the inevitable result of the industrialization and the urbanization.However,in the process of land management,with the phenomenon of the yield per unite declining,that is,the land area will not necessarily lead to the increase of The Land Scale Efficiency.According to the Division Theory,the nature of Scale Economy is the division and specialization,then Does The Agricultural Socialization Service from the vertical division of agriculture can affect the Land Scale Efficiency? As the gap between agriculture and non-agricultural income gradually widen,more and more part-time household,the extensive land management is more common,and the is considered the best alternative to the labor force,Does the Agricultural Machinery Socialization Service can improve the extensive management of agriculture? How the impact? To answer these questions,can deepen the understand of the theory of Technical Efficiency and Vertical Division of Agriculture,provide some references for decision makers in the field of agricultural production,help agriculture to rational practice.The purpose is to answer the scientific question of how the Agricultural Machinery Socialization Service affects the Land Scale Efficiency.The fundamental purpose is to reveal the inherent laws of the impact of the Agricultural Machinery Socialization Service on the Land Scale Efficiency.The main research contents are as follows:(1)Describe the present situation of the Agricultural Machinery Socialization Service and the Land Scale and efficiency.Observe the change of the Land Scale and efficiency with the change of the Agricultural Machinery Socialization Service in the level of practice.(2)Analyze the relationship between the Agricultural Machinery Socialization Service and the Land Scale Efficiency.On the basis of the Qualitative and Quantitative Analysis,considering the causal relationship between the Agricultural Machinery Socialization Service and the Land Scale Efficiency,analyze the influence mechanism of the Agricultural Machinery Socialization Service on the Land Scale Efficiency.(3)Based on the influence mechanism analysis and practice,puts forward the empirical hypothesis,constructs the Multiple Linear Regression Model,make an empirical study on the influence of the Agricultural Machinery Socialization Service on the Land Scale Efficiency and analyzes influence degree and influence direction.(4)On the basis of the empirical results,combines with the theoretical argument,analysis of the impact process of Agricultural Machinery Socialization Service on the Land Scale Efficiency.The results show that:(1)The Agricultural Machinery Socialization Service has a steadily positive effect on the Land Scale Efficiency,and the Land Scale Efficiency can alleviate the extensive management contradiction with the land scale expansion.The impact of The Agricultural Machinery Socialization Service on the Land Scale Efficiency is mainly from the aspects of the alternative labor and the organization,both of which have a significant positive effect on the efficiency of the Land Scale Efficiency,and by pass the 1% significance level test.Among them,the degree of organization of Agricultural Machinery Social Services is the strongest,and its influence coefficient is 0.1141.The impact coefficient of the degree of Agricultural Machinery Social Services replace of labor is0.0795.(2)The positive effect of Agricultural Machinery Social Services on the Land Scale Efficiency is not directly related to the land area.The negative effect of land fragmentation and the part time will weaken the positive effect of Agricultural Machinery Social Services on the Land Scale Efficiency.(3)The land area has a significant negative impact on the Land Scale Efficiency,and the fragmentation of land and the part time household have a insignificant negative impact on the Land Scale Efficiency.the effect of the part time household on the Land Scale Efficiency is the strongest,then the effect of land fragmentation and land area.The influence coefficients of which are-0.0649,-0.0064 and-0.0006.Because of the part time household and the lack of labor lead to the extensive land management is the main impact factors on the Land Scale Efficiency.Land fragmentation will also restrict the achieve of the Scale Economy.(4)The education level of farmer households has a insignificant positive effect on the Land Scale Efficiency,the farmer's household age has a significant positive effect on the Land Scale Efficiency.The influence coefficients are 0.016 and 0.0043.The Agricultural Machinery Social Services mainly through the re-allocation of resources,change the degree of organization of agricultural management subject to influence the Land Scale Efficiency.The policy implication of the research results is to improve the degree of specialization of the Agricultural Machinery Social Services to achieve the corresponding of the supply and demand,to improve the specialization and organization of the agricultural management subject,strengthen the management and improve the Land Scale Efficiency.Specific recommendations are:(1)Cultivate the subject of Agricultural Machinery Social Services,the relevant policies to support the establishment of Agricultural Machinery cooperatives.improve the management mechanism of agricultural cooperatives,reduce the threshold of small farmers into the community,encourage farmers to actively enter the community,regular training agricultural machinery operators,cultivate specialized agricultural machinery service personnel.(2)Speed up the establishment of agricultural machinery social service intermediary agencies,to achieve the corresponding of the supply and demand of the Agricultural Machinery Social Services,Government as the main body,to book the registration for the supply body of Agricultural Machinery Social Services,establish the mechanism of the integrity file,standardize the market of the Agricultural Machinery Social Services.Establish the formation-based Agricultural Machinery Social Services management mechanism,actively explore the "Internet + Agricultural Machinery Social Services intermediary" model.Expand the scope of intermediary,improve intermediary services.(3)Increase agricultural machinery R & D investment,expand the scope of Agricultural Machinery Social Services operations.Strengthen the cooperation with foreign research team,and actively introduce foreign advanced equipment.(4)Increase farmer education and training efforts to improve farmers' agricultural production capacity.Regularly carry out agricultural production knowledge training and experience exchange issue some relevant policies,and actively introduce agricultural university graduates into the process of the agricultural production and management. |
