| Since the reform and opening up,China’s agricultural and rural economy has developed rapidly.Grain output has reached new highs,and farmers’ income has also been greatly improved.However,with the further developing of the reform,some problems have also emerged,such as increasing agricultural non-point source pollutions、increasing risks of agricultural product quality and safety and increasing difficulties in farmers’ income growing,which make the further development of agricultural and rural economy difficult.Our country attached great importance to the modern agricultural development mode of the combination of planting and breeding.Rice and shrimp culture is one of the specific modes of combination of planting and breeding.In practice,the key to the rice and shrimp culture technology transformed into real productivity lies in the final adoption behavior of farmers.Based on the theory of household behavior and diffusion of innovation and the data on the spot from rice shrimp farming farmers in Chongzhou city,firstly this paper analyzes the status quo and problems of rice and shrimp culture in Chongzhou city;and then this paper makes empirical research on technology adoption behavior and its influencing factors by 2)4)4)(8 regression model;finally this paper summarizes and puts forward relevant policy suggestions.The main research conclusions of this paper are summarized as follows :(1)the effect of rice and shrimp culture on farmers’ income increase is obvious,and the yield per unit area is about 3,590 yuan/mu.the input cost per unit area rises to 2,276yuan/mu.the profit per unit area is about 1314 yuan/mu.(2)there are some problems in the development process of rice and shrimp culture in Chongzhou city,such as market price wave,farmers’ insufficient production experience,insufficient financial support,and insufficient brand influence of rice and shrimp.(3)the adoption behavior of rice and shrimp culture technology is influenced by personal characteristics,family characteristics,information channels,external environment.Among them,the health status of decision-makers,family agricultural income,farmland quality,credit constraints,government subsidies and others’ demonstration significantly positively affect the technology adoption behavior of farmers,while the technology demonstration household has significant negative influence on the technology adoption behavior.The multicollinearity test shows that the original model has a certain degree of multicollinearity,and the best model is screened by stepwise regression.The comparison between 2)4)4)(8 model and model shows that the regression results are robust under different estimation methods. |
