Study Of Farmers' Income Structure Change And Its Causes

With change of rural households' income growth in different phases, the substance of problems on rural households' income and its structure has changed. Under the new position, farmers' income has been not only a simplex "three-agro" problem, but also a big problem concerned with national macro-economy posture and international economy changes. The changes of rural households' income structure can reflect that of substance of problems on their income commendably. Based on reason above, researches about that are made in the article.The route of this research is: based on systematic analysis of theory of rural households' income structure transform, also its related researching results and methods, taking rural households' income structure as cut-in point, criterion analysis and demonstration research are used to analyze the variance process of farmer income structure and anatomize the cause of income structure variance from two aspects of microcosmic and macrocosmic. Finally, the method of data envelopment analysis is used to estimate and evaluate the rationality of farmers' income structure. Founded researches are evolved according to the route above, and the main content of the article includes several parts as followed:Section 1: Evaluating the theory of rural households' income structure transform and its related researches. Among the theory research, main parts are retrospection and evaluation on farmer economic behavior theory, structure transform and economy increase theory, region economy development theory and system transform increasing theory, during which, based on commenting and analyzing rational dispute of farmer economic behavior, the author pointed that farmer behavior will be influenced by historical culture and environment, and then makes the presupposition that farmer economic behavior is rational. At the same time, based on using correlate income structure theories for reference, the author framed the statistics range of farmers' income source, and selected evaluating index and measuring methods used by the research according to research purpose.Section 2: Analyzing the general trend of rural households' income structure fluctuating. In this part, some structure analysis index including alteration degree of income structure and structure resembling degree are mainly used to measure alteration value and trend of farmers' income structure, at the same time, contribution to farmers' income increasing is divided into absolute contribution and comparative contribution and these index are measured.Section 3: Analyzing microcosmic and macrocosmic cause of rural households' income structure fluctuation deeply. About microcosmic cause, farmers' family life cycle, asset level and structure alteration are mainly analyzed, and about macrocosmic cause, region difference and system transformation are mainly analyzed.In the analysis of cause of farmers' family life cycle alteration, family population size, main laborers' ages and laboring population burden coefficient are used to reflect altering of farmers' family life cycle and reviewing the rules of alteration of farmers' income structure combined with farmers organization evolving. Finally, Pearson correlation tests about family population size and farmer' income from different source are made, and the results indicate: main labors' ages in the family and outgoing income assume upper negative correlation, butit assumes positive correlation concerned with family dealing income and transferring income; family population size and outgoing income assumes negative correlation, but it assumes negative correlation concerned with transferring income; laborers' burden coefficient and outgoing income assumes negative correlation, and it assumes positive concerned with property income. In the analysis of cause of assets level and structure, method of more-layer intercross grouping is used to analyze rules of farmers' income structure altering in different collocation structure of substance assets and manpower assets. And according to economics meaning of substitution e...
