| The irrational use of chemical fertilizer is an important cause of non-point source pollution.Soil testing and formulated fertilization is an effective method and technology to reduce non-point source pollution,improve fertilization efficiency and soil quality.It is an important way to reduce non-point source pollution for large-scale farmers to change their fertilization views and methods.It is of great theoretical and practical significance to study the technology adoption behavior of scale operation farmers.On the basis of theoretical thinking and mechanism analysis,this paper uses 233 survey data of three cities and eight counties in Shandong Province to establish a logit econometric model.Under the control of household head characteristics and household management characteristics,this paper analyzes the impact of social capital and management ability of scale operation farmers on technology adoption,and uses bootstrap method to test the intermediary role of management ability.The research conclusion is credible The research method is scientific and the countermeasures are feasible.The innovation of this paper is that the research object is the scale operation farmers,and the scale operation farmers are the most likely to give priority to the use of soil testing and formulated fertilization technology,which has practical significance for Rural Revitalization and leading the development of modern agriculture;Taking the management ability of scale operation farmers as an intermediary variable,that is,in the process of scale operation farmers’ social capital affecting the adoption of soil testing and formulated fertilization technology,the management ability has an indirect effect,which further enriches the existing research results.The possible shortcomings of the paper are as follows: the application of soil testing and formulated fertilization technology in different regions is different,the survey objects of this paper are concentrated in three cities of Shandong Province,and the policies and applicable conditions of the technology in other regions are not taken into account.Guided by the basic principles of agricultural economics,econometrics and other disciplines,this paper makes good use of the research methods of qualitative analysis and quantitative analysis,which fully reflects the author’s solid economic theory foundation and has the ability to engage in scientific research in this field.Taking a comprehensive view of the full text,the structure is reasonable,the viewpoint is clear,and the thesis follows the basic norms and ideas of academic research.It is an excellent master’s thesis. |
