Adoption Behavior And Effect Evaluation Of Rice And Crab Co-Cropping Patterns On Family Farms

At present,resource and environment constraints have become a major bottleneck for the healthy and sustainable development of the economy and society.Agriculture not only needs to break the tight resource and environment constraints faced by its own development,but also needs to reduce environmental pollution and increase farmers’ income while contributing to environmental governance and ecological protection.State and government of planting and raising mode of ecological management and promotion is also increasingly seriously,2019,"the leading green development supporting system construction management approach(trial)" proposed that to vigorously develop farming,ecological circular agriculture,vigorously foster agricultural products brand,increase the green high quality supply of agricultural products,improve the quality and efficiency of green agricultural products.The No.1 document of the CPC Central Committee in 2021 calls for continued efforts to reduce the amount of chemical fertilizers and pesticides and increase their efficiency,promote the use of green products and technologies for the prevention and control of crop diseases and insect pests,strengthen the resource utilization of livestock and poultry waste,strengthen supervision over the quality and food safety of agricultural products,and develop green agricultural products,organic agricultural products and geographical indication agricultural products.As an ecological planting and rearing model,the rice and crab co-cropping model can increase farmers’ income,reduce the amount of chemical fertilizer and pesticide and increase the efficiency,and meet the market demand for high-quality agricultural products.However,the popularization of co-cropping mode of rice and crab is not optimistic.Therefore,it is particularly important to explore the impact of rice-crab co-farming behavior on income effect and analyze the main influencing factors of rice-crab co-farming behavior.The research contents include: First,combined with the results of field visits and questionnaires,descriptive analysis was conducted on the adoption behavior of rice and crab co-cropping pattern in Yanbian area,laying a solid foundation for empirical analysis and policy recommendations of this study;Secondly,the propensity score matching method(PSM)was used to determine the effect of adoption behavior of rice and crab co-cropping patterns on income.Thirdly,the dual logistics model was used to empirically analyze the mechanism of technology perception and government incentive on the adoption behavior of rice-crab co-cropping mode.This study mainly draws the following conclusions:First,the adoption behavior of rice-crab co-cropping pattern can significantly improve the income effect.After adopting the co-cropping mode of rice and crab,although the rice yield decreased due to the reduction of the use of chemical fertilizers and pesticides,the quality of organic rice was significantly better than that of ordinary agricultural products,so the price of green agricultural products was higher than that of ordinary agricultural products,and the production of rice crabs also met the market demand.Therefore,In theory,adopting the rice-crab co-cropping model could increase the income effect of farmers.Model for reality check middle-season rice crab has influence on income effect,this study based on 260 rice farmers in the field survey data,the yanbian area using tend to score matching method(PSM)empirically the effect of rice crab work mode adopted behavior,the results showed that the rice crab make model has significant impact on farmers income effect,The average effect change degree of household income was 14.8%.Therefore,adopting the rice-crab co-cropping model has a significant positive effect on the increase of income effect.Secondly,the perceived characteristics of farmers had a significant positive impact on the adoption behavior of rice and crab co-cropping patterns.In this study,farmers’ perceived characteristics were divided into perceived economic effect and perceived ease of use,and the binary Logistic model was used to analyze whether farmers’ perceived characteristics had an impact on the adoption behavior of rice-crab co-cropping mode.Among them,perceived economic effect has a positive impact on farmers at 10% level,and perceived ease of use has a positive impact on farmers at 5% level.This is due to the perceived economic effect on behalf of farmers are expected to net income,perceived ease of use on behalf of farmers to adopt cost perception,according to the theory of rational smallholder farmers behavior,the economic effect is the fundamental driving force of farmers shift production behavior,that is,only when farmers consider adopting rice crab make pattern of net income and cost if you have any change after we will decide whether or not to accept.Therefore,this study concluded that the perceived characteristics of farmers had an impact on the adoption of rice-crab co-cropping mode.Thirdly,government incentive had an effect on the co-cropping pattern of rice and crab.This study explores the impact of government incentives on farmers’ adoption behavior from the dual perspectives of government subsidies and government incentives.It is found that government subsidy has a positive impact on farmers’ behavior at 1% level,and government training has a positive impact on farmers’ behavior at 10% level.This is because the farmer as rational individual,the pursuit of maximizing economic benefits and minimizing risk is the essential characteristics of its participation in social economic life,among them,the government subsidies can reduce the marginal cost of farmers to adopt behavior,government behavior training can reduce farmers to adopt the learning cost,caused by the adoption of cost reduction will play a promoting effect on peasant household adopted decisions.Therefore,this study concluded that government incentives can significantly affect the adoption behavior of rice and crab co-cropping patterns.Based on the above conclusions,the following policy suggestions were put forward:improve the support mechanism of rice and crab co-cropping pattern,and steadily promote rice and crab co-cropping pattern;To change the characteristics of farmers’ perception and strengthen the publicity and education of ecological agriculture;We will increase government financial support and improve preferential policies for rice and crab co-cultivation.
