The Summary and Evaluation on the Research of Agricultural Contract Theory
Beginning from rural household behavior as micro-body,this article analyzes the fluctuation of China's grain production in recent years based on C-D function.The study illustrates that the price change of farm product could result into the adjustment of crops management structure as well as output fluctuation,and the increase of fertilizer input positively influences grain yield per unit,however,our study also indicates indistinctive effect of fluctuation of comparable labor price over labor input per unit area together with unremarkable influence of technological progress on the increase of grain yield per unit since 1980s,and the negative effect of natural calamity over farmers can partly be compensated by intensive farming of grain in non disaster-hit areas.At last we point out the key to strengthen up effective macro supply capability is to perfect micro basis such as price of crops and inputs,technological progress as well as agricultural infrastructure.
