What Is The Progress Direction Of Impact On The Export Of Chinese Agricultural Productivity: Labor-saving Or Material-saving?

Capital productivity analysis commonly used as an agricultural input factors more general. This article according to the status of per capita arable land scarce, will refine the elements, and will assume the production function is a feature enhanced under the premise of CES functions, by using Klump’s standardized supply side of the system, we analyze the main crops of several elements of the actual production of refined biased technological progress, as well as the impact of bias on these crops for export, combined with the common trend study presented to China the agricultural sector formed an overall understanding. After calculation we found that During 2004 to 2014, the actual production of four crops in a non-neutral technological progress. The elasticity of substitution between factors of production the actual four crops is less than 1, more significant complementary relationship, and on the performance of the overall efficiency of fertilizer elements of progress rate is faster at the beginning but then slower than the labor element efficiency progress rate, therefore the direction of technological progress change from labor-saving to material-saving. On this basis, by setting the relevant variables, using panel data regression further analysis the different impact on exports of four crops of two kind of bias respectively. According to the regression results, we found that labor-saving bias tend to play a significant role in promoting export while material-saving bias tend to act negatively, and showed inhibitory effect on the trend. This shows that technical progress biased may have different influence on production and export, by the light of this, the agricultural sector to enhance the yield simply by increasing productivity so as to improve export methods are not always effective, we need to recognize biased technological progress differences in the actual impact, so the development of appropriate policies should reflect the different emphasis depending on the situation.
