| The development of irrigation and water conservancy has a pivotal role for improving agricultural production and income, maintaining social stability in rural areas, and ensuring national food security. However, with the accelerated advance of industrialization, urbanization and agricultural modernization as well as the impact of global climate change, contradictions of increased population and water shortages become more prominent, delayed construction of irrigation and water conservancy become more prominent. These problems have become a major factor restricting the development of agricultural production and endanger national food security. Therefore, strengthening the construction of water conservancy in China has becoming an integral part of solving the problems of water resource in China, and developing agricultural production. In2009, by jointly promoting of the Ministry of Finance and Ministry of Water Resources, construction of key counties about small-scale irrigation and water conservancy has began nationwide piloting, as a major agricultural province, Jiangsu has constructed about69key counties, The research of its investment results have important practical significance for the development of small-scale irrigation.Based on the theory of public goods, public policy evaluation and customer satisfaction, this paper conscientiously studied previous studies in irrigation and water conservancy and other aspects from domestic and foreign scholars, used methods of qualitative and quantitative research and comprehensive analyzed the current investment in key counties of Jiangsu Province form Current Situation, the economic efficiency of investment, the social effects of investment, and finally put forward relevant policy recommendations.Firstly, this article tried to define the scope of the study, and pertinently learned the theory of public goods, public policy evaluation and customer satisfaction theory, then this article summarized systematically existing domestic and international aspects of rural public goods related research, as a theoretical foundation for the full text.Secondly, the author attempted to analyze investment current situation of key counties of small water conservancy in Jiangsu Province from the overall level, the main aspects included investment structure, construction, investment effectiveness. On this basis, the author tried to identify the main problems of investment.Thirdly, based on macroeconomic statistics, this article took an empirical analysis of the economic effect of investment in key counties of Jiangsu Province. In this part, the author conducted a brief introduction to research methods-CD production function of the contents of this section, and then based on the first and the second batch of44key counties’ county-level data the author built improved CD production function model to calculate the effect of the impact of investment in key counties for agricultural production using EVIEWS software. The calculated results show that although the key counties’ funds investment indirectly affected agricultural output value, its elastic coefficient was highest in each factor input, the key counties investments generated good results. In terms of regional differences, the investment effect in the water-rich region was better than the water-shortage region, but the gap of regional differences was not obvious.Then, this study based on the data by field visiting the more representative key counties Shuyang and Baoying Counties in Jiangsu Province, analyzed the social effects of investment in key counties. Before Empirical Analysis this section have a brief research location overview and sample profiles. In the empirical analysis the author used the Probit model introducing regional dummies to do in-depth analyze of the factors affecting farmers satisfaction. By analysis of satisfaction, we found that the overall level of satisfaction of the farmers on the construction of key counties is general. The Baoying satisfaction is higher than Shuyang satisfaction. In the analysis of influencing factors, in addition to the respondents personal, family characteristics have a certain influence on satisfaction, irrigational convenience, facilities maintenance situation, the attitude of the village committee, the funding mechanism have the impact on farmers’ satisfaction. As satisfaction of the farmers subject to many factors, investment and construction of key counties must be multi-pronged approach, emphasize on facilities maintenance, management of late on the basis of further increase investment, improve the investment mechanism, strengthen financial supervision. Finally, on the basis of the above analysis and research, the author draw some conclusions about the small-scale irrigation and water conservancy investment in key counties, and proposed to effectively improve the effect of investment in key counties for Several suggestions. |
