| "Three rural issues"is critical for building a harmonious society and new socialist countryside. The 12th Five-year Planning Outline points out that it's a significant task to carry forward agricultural modernization in the synchronous deep development of industrialization and urbanization, the focus of whole party's work must adhere to solve the agriculture, rural areas and farmers, to plan urban development as well as rural's, to insist on supporting agriculture by industry, supporting countryside by cities , affording more and asking less, the policy of strengthening and benefiting rural issues should be intensified to consolidate the basis of agricultural and rural development, to improve agricultural modernization level and farmers' living standard and construction better life for farmers. To speed up the development of modern agriculture, strengthen rural infrastructure and public service, broaden the channels to increase rural incomes, perfect the mechanism of system of rural development. The Outline also pointed out that to promote the country's economy rely more on technology innovation drive, so we must fully carry out education, national long-and mid-term science and technology, talent program, improving technological innovation capability, accelerating education reform development, displaying the human resources advantages, laying solid technology and human resources foundation to accelerate the transformation of the mode of economic development, realize the comprehensive construction well-off society goal.This study aims to reference the basis of previous studies of Xinjiang, to comprehensively study the rural human capital investment and farmers' income, rural surplus labor transfer, rural economic development system, and then analyze rural human capital investment situation and existing problems of Xinjiang under the new situation, to analyze its effect on the development of rural economy, and finally draw some conclusion and corresponding countermeasures which can be beneficial for the development of rural economy in Xinjiang, to provide the theory basis and the decision-making basis for fundamentally cracked Xinjiang "three rural issues".The paper centers on the rural human capital investment unfolds in Xinjiang, first explains the purpose and significance of the study, research contents and methods, and points out the possible innovation and deficiency. Then it states and valuates the human capital related theory,problems and research status home and abroad. Secondly, it analyzes the present situation of rural economic development of Xinjiang, mainly about farmers' income, the transfer of rural surplus labor force, rural economic development. Thirdly, it constructs the influence factors index of rural human capital, on that basis to estimates the comprehensive level of the rural human capital investment in Xinjiang by using the factor analysis method. Fifthly, on the base of measuring comprehensive level of the rural human capital investment and rural economic development status in Xinjiang, it uses vector auto-regressive and impulse response function and variance decomposition, multiple regression, ridge regression to analyze the relationships between the rural human capital investment in Xinjiang and farmers' income, the transfer of rural surplus labor force, the rural economic development distinguishably. Finally, based on human capital perspective, it puts forward how to speed up the development of rural economy in Xinjiang.The results of this study shows that: (1) in Xinjiang the rural human capital investment and rural income exist cointegration relationships, Xinjiang rural income changes depends not only on the comprehensive level of human capital short-term changes, but also by the last issue of rural income balanced level deviation, with an estimated coefficient of the error term -0.86, reflecting the deviation of correction is stronger. Granger causality test shows that the rural human capital investment in Xinjiang has no granger causality with farmers' income, the impulse response shows the rural human capital investment in Xinjiang has the strong positive effects on farmers' income, and the variance decomposition indicates that the rural human capital investment's influence is stably about 25% of prediction error. (2) When the comprehensive level of rural human capital investment increased by 100 units, it will transfer the surplus labor of 9.81 million in Xinjiang, which indicates that investment in human capital has a great influence on transferring the rural surplus labor force. But it does not the most important factor. Therefore, we must attach importance to the rural labor force of human capital investment, and really achieve the smooth progress of rural surplus labor transfer. (3) the elastic coefficient of rural human capital investment in Xinjiang is 0.28, and the contribution of the rural human capital investment is 28.17%, half of the material capital contribution rate, moreover, the rural human capital investment in Xinjiang is in a low level of externality, thus, the style of rural economic development in Xinjiang belongs to the typical cost-driven substance capital. |
