Study On The Contribution Of Agricultural Mechanization To Grain Output Efficiency

Grain production is one of the important fields in agricultural production. The measurement of grain output performance is the ultimate total output and level with reasonable allocation of all kinds of input factors. As the most important equipment and factor, agriculture machine makes great contributions to the grain output performance by impacting all the factors, and the results are positive.The analysis of contribution made by agricultural mechanization to agricultural production lies in the scope of productivity estimation and great differences do exist between homes and abroad. Few analysis are focusing on pure agricultural mechanization in foreign countries, and about the methodologies, the development countries mostly analysis these issues quantitatively and concentrate on the optimization problems of agricultural mechanization. However, the developing countries are mostly analysis the policies issues.In our country, with the main focus on qualitative analysis, we study the following problems, systematic analysis of mechanization, constraints factors impeding the development, the important role and status in the national economy, resolving the theoretical basis of development, statement of stages characteristics and instruct the development scientifically. On the quantitative analysis scope, we focus on systematic analysis, optimization analysis and contribution estimations.Under the background mentioned above, the analysis comprehensively overview the related research on mechanization and agricultural development, retrospect and analysis the way mechanization has been through of our country and its shortcomings. By resort to the definition of performance in related areas, this analysis put forward and lay out the meaning of grain production performance. And then, relationship between development of mechanization and grain production performance is given theoretically, followed by factors analysis that will have effect on the performance of grain production. By pick Hubei province as a sample, we use econometric methods to estimate the contribution that agricultural machines make to the grain production performance of Hubei. Finally, policy instructions are put forward concerning agricultural mechanization. The context is arranged as follows:(1) Review and analysis research related to the agricultural mechanization, more focus is given to the review of contribution estimation;(2) Retrospect the way agricultural mechanization has been through, and analysis its present situations, strengths and weakness;(3) By referring to various kinds of definitions concerning performance in related fields, give out the definition of grain production performance. On the basis of that, conditions, influence factors and estimation methods are all given;(4) Analysis the relationship between agricultural mechanization and grain production performance theoretically;(5) Review of estimation methods on contributions agricultural machines make to the agriculture production;(6) Select Hubei province as an example and estimate the contribution that agricultural machines make to the grain production performance;(7) Mechanization patterns of selected developed countries is analyzed and contrasted in order to draw some experience and implications;The conclusions achieved through the study are as follows:(1) Referring to various kinds of definitions concerning performance in related fields, give out the definition of grain production performance. For the first time, we systematically analysis's the mechanization as one factor affecting the grain output.(2) Reviewing various estimation methods on contributions agricultural machines make to the agriculture production. Selecting proper variables, models and data, we estimate the contribution made by mechanization to output in Hubei province.(3) Taking a close look at the successful experiences of foreign countries, we analysis the development patterns and contribution studies of agricultural mechanization made to grain output performance of foreign countries, and suggest that Hubei province should increase total power of agricultural mechanization, diffuse different scale of production mechanization, and some advices are given to further improvement of the contribution of mechanization to output performance.
