Study On The Land Capital Investment Behavior Of Farmer Households

The historical trend of agricultural modernization is irreversible, and agricultural mechanization is one of the importance content and the main hallmark of agricultural modernization. So to speak, without agricultural mechanization there would be no agricultural modernization. Most occident have basically achieved agricultural mechanization in 1940s to 1950s, and they have entered in the stage of comprehensive agricultural mechanization since the 1950s. Japan and Korea, which are densely populated Asian country, also have basically achieved agricultural mechanization in 1960s and 1980s, and they have entered in the stage of comprehensive agricultural mechanization since 1970s and 1980s. At present China's agricultural mechanization is in a transition phase, that is from the primary stage to the middle stage. The proportion of private investment in total farm machinery investment was over 90%, farm households have become the most principal unit of using farm machinery. Studying agricultural mechanization from the perspective of farmer households will be an important and indispensable part for research topics of our country's agricultural mechanization.There are three aims in this study:The first one is that, according to households behavior theory and the economic environment farmer households faced, we construct a theoretical model which is suitable for analyzing farmer households behavior in our country. The second aim is to carry out a theoretical analysis for farm households using farm machinery behavior, based on the households behavior model we constructed, and to reveal the behavioral logic that whether households use farm machinery and how to use it. The last one is to demonstrate the theoretical analysis conclusion of farm households using farm machinery behavior by survey data of farm households.This thesis is divided into seven chapters. The contents of each chapter will be introduced as follows.Chapter 1:Introduction. This chapter introduces the background and significance, research objectives, research content, research methods and innovation of the papers.Chapter 2:Literature Review. This chapter will commentate households behavior theory by dividing it into three sect:formalism, noumenalism and realism, and analyze the essence of households behavior theory by describing a generalized households behavior theory. And then, this chapter summarized domestic and foreign literature of farmer using farm machineryChapter 3:Constructing farmer households behavior model. This chapter constructs a theoretical model which is suitable for analyzing farmer households behavior in our country. Section 1 of this chapter studys consumer behavior of farmer households by analyzing farmer households utility function. Study suggests that:Income and leisure time are two basic elements which farmer households consume; CES utility function with elasticity of substitution greater than 1 is suitably to describe our county's farmer households utility function; The size parameters of farmer households utility function reflects the households preference to income and leisure, and the households time allocation sensitivity to the changes of labor remuneration rate. Section 2 of this chapter studys farmer households production behavior by using labor remuneration curve. Study suggests that:The direct purpose of households production behavior is to obtain income; Labor remuneration curve is a effective tool to describe households production behavior, because of labor remuneration curve reflecting the relationship between households work time and households income; Households production mode is composed by agricultural production mode and non-agricultural production mode; Choice of households work time is discrete, because specific production mode needs relatively fixed work time input, and choice of households production mode is discrete; Labor remuneration curve of households production mode i can be described as Yi= Tfi·rfi+Twi·rwi+Yv, (i∈=I={1,…,n). Section 3 of this chapter constructs the farmer households behavior model by analyzing the relationship between households consumer behavior and households production behavior. Study suggests that:the ultimate objective of households behavior is to pursue consumer utility maximization, constraint condition of utility maximization is households production environment and the households total available time. The algebraic form of households behavior model can be expressed as:Chapter 4:The general analysis on behavior of farmer households using agricultrual machinery. This chapter reveals the behavioral logic that whether households use farm machinery and how to use it. Section 1 of this chapter analysis the impacts of farmer households using farm machinery on households production. Study suggests that:the impacts of farmer households using farm machinery on households agricultural production can be summarized in two point, changing the households agricultural work time and changing households agricultural income; Using farm machinery can release famer from agricultural work by shortening agricultural work time, this may make farmer getting more non-agricultural work opportunities. Section 2 of this chapter analysis the behavioral logic that whether households use farm machinery. Study suggests that: behavior of households using farm machinery acts as a specific example of households production behavior, which can be analyzed by using the households behavior model constructed above; Tolerance value(abbreviation TV) is defined that the maximum reduction of farm income which households can accept after using farm machinery; the behavior of households weather using farm machinery depends on the comparing the size betweenΔYf (The real change of agricultural income after using farm machinery) and TV; If-ΔYf>TV, the choice of households nonuse farm machinery is the optimum, ifΔYf
