Research On Regional Difference Of China Agriculture Labor Productivity

Since the Chinese reform the bulk of the labor rolls from agricultural department tonon-agricultural sectors, the agricultural labor proportion declining overall labor force.China’s economic development and social transformation have entered an important stage.Only with higher levels of agricultural labor productivity, get more agricultural productswith less labor input, help more agricultural labor transform to non-agricultural sectorscan ensure the realization of economic development goals. Furthermore moderndevelopment economics pointed out that higher level of agricultural labor productivity isthe prerequisite for economic development. Currently the agricultural labor productivityof china is really low, at the same time the regional difference is obviously which wouldslow down the development of Chinese economic. Study of China agricultural laborproductivity, measure the growth and regional difference of agricultural laborproductivity, explain the reason of regional difference is significant which can help usreach a higher level of agricultural labor productivity, enhance the stability of Chinaagricultural economic development.This paper overviews related theories from domestic and international, reviews thepresent situation about China agricultural labor productivity through literature. Based onstochastic frontier function, adopts Counterfactual Analysis method and Shapley Valueanalysis method to analysis the evolution of China agricultural labor productivity regionaldifferences, judge the importance of every influence factor to the regional differences,measure the contribution of every influence factor to regional differences, analyses thedecision mechanism of every influence factors with time.The kernel density estimationmethod was used to investigate the distribution of agricultural growth in China using1988-2008panel data of the28provinces on the mainland. Some general remarks andconclusions can be made.Firstly, the distribution of agricultural output per worker evolved from a unimodalinto a bimodal distribution. Secondly, agricultural material consumption, labor-scale,farmland accumulation, efficiency change and technical change are the source of china agricultural labor productivity growth; Thirdly, the contribution to the regional differenceare:39.84%,9.28%,24.22%,21.58%and5.08%, obviously material consumption,labor-scale and efficiency change are the main reasons of the regional difference deependuring1988-2011. Last, efficiency change plays a more and more important role, thecontribution of it increases with time, but the contribution rate of material consumptionand labor-scale decreases slowly with time, the contribution rate of technical change andfarmland accumulation is stable.Confronted with such conclusions, some policy proposals are as follows. Firstly, asargue above, local governments all levels should increase the agriculture financial inputstrengthens the countryside infrastructural facilities; Secondly, encourage technologicalinnovation and technological advancement to enhance the agricultural technical efficiency;Thirdly, pay more attention on agricultural extension and establishment of thepopularization system; Last, accelerate agricultural labor transference, decrease the scale ofagricultural labor-force.
