Research On The Effect Of Rural Labor Force Structure On Grain Yield In Hunan Province

Large-scale cross-regional transfer of the labor force in the rural area is a special phenomenon of China’s economic and social transition period,With the deepening of rural reform and opening up,with the deepening of rural reform and opening up,national policy to relax,the scale of rural labor force transfer normalization and showing a growing trend,it has a profound impact on the development of our country’s economy,both inflow or outflow has its positive effects also led to a series of social problems that nots allow to ignore.At present,throughout the domestic and foreign research literature,research on rural labor’s literature abound.Study on grain production are numerous.However,the research literature only a few which combined with the rural labor force structure changes and food production,some more than from the rural labor force is a characteristic,such as labor“age structure”,“sex structure”,"by education level"and so on,to study the influence of grain.In this paper,from the overall grasp the rural labor force structure,the effects on grain yield caused by the structural changes of the rural labor force,the theory at home and abroad to undertake summing up,laid the theoretical foundation of this paper.Based in Hunan Province and its subordinate two city,Changsha,Shaoyang City,the three sample unit of the rural labor force structure as a whole based on the analysis,draw lessons from existing research results at home and abroad and the three sample unit data,By building SPA beyond the logarithm stochastic frontier production function model,using maximum likelihood estimation method,using stochastic frontier production function dedicated software Frontiers Version 4.1,Measure of rural labor force structure of grain production technical efficiency change,measure out the sample unit2005-2012 years in Hunan Province rural labor force structure changes of grain production technical efficiency,at the same time,through technical non efficiency function model to analyze structural changes of the rural labor force affecting the efficiency of production technology of food,draws the main conclusions are:1.The transfer of rural labor force in Hunan province had no significant effect on grain yield.According to the empirical results,engaged in grain production of labor output elastic coefficient 1~?is-0.1337,at the statistical level was not significant,showed no significant of technical efficiency of reverse function,the amplitude is small;quadratic term coefficient~?11is-0.0369and time trends cross terms~?6is-0.4088 are significant negative level,showed that with the time changes in labor input factors impact on the technical efficiency decreased.Hunan Province grain production technical efficiency level is relatively stable,and higher level.Thus,at present,Hunan Province rural labor force continuous transfer is consistent with that of stable increase in grain production trend,does not significantly affect food security.That under the premise that ensure the safety of food production,from the point of view of development,rural labor transfer in hunan province also has a certain space.2.The effect of rural labor structure change on Grain Yield in Hunan province is not efficient.Hunan Province rural labor force in the total resource reduction,human capital the ascent of the whole,however,engaged in grain production of local labor weakening mixed changes,showing a structural imbalances in the age structure,gender structure and cultural level of the structure.According to the empirical results,in addition to the total population of rural labor regression coefficient 1~?is negative,the aging of the rural labor force of regression coefficients~?2and feminine regression coefficient~?3and average years of schooling of the regression coefficients~?4are positive,showed improvement in left behind rural labor structure weak level,is conducive to the improvement of technical efficiency of food production.Finally,put forward:combine the local actual conditions,formulate appropriate policies of transferring the rural labor force;Increase human capital investment of finance in rural areas,open training courses,to strengthen the training of women and the elderly,to improve their own cultural quality and new agricultural science and technology level,the competent agricultural modernization development needs,further deepen the reform of the land;promote moderate scale management;establish and perfect the reasonable land circulation system,to achieve the optimum combination and allocation of land and labor;improve the rural social security system,ensure security of agricultural aging labor Village can no worries to withdraw from the field of grain production,the labor force engaged in food to maintain a high quality level,thus gradually separation the aging of the labor force;by improving the living conditions of rural areas,improve food production conditions,to attract more Young and high quality migrant labor force back to the land,engaged in food production etc.countermeasures and suggestions.To attract more young people out of work,the quality of the labor force back to the land engaged in food production and other countermeasures and suggestions.
