Study On The Supply Effectiveness Of China’s Farmland Water Conservancy

Farmland water conservancy construction is one of the basic engineeringconstructions, also the key factor of stabilizing the position of agriculture andensuring national food security. The problems of “lay emphasis on scale construction,constructing especially key projects, but ignore small construction, supervising andsupporting facility construction”,“also lacks incentive in the property rights systemseriously” have been existent for a long time in China’s Farmland Water Conservancysupply, which heavily hamper the effectiveness of farmland water conservancy supplyin china. The central government continuously increases investing funds into theFarmland Water Conservancy in the new century, but still difficult to make up for thelosses caused by the amiss supply mechanism--although backbone projects aregradually improved, the problems of “lacking management” and that problems of “thestate can’t supervise; the village collective’s supervision is not in place; the farmershave not ability to do” are still very serious in vast rural areas.The standard of judging the superiority of Farmland Water Conservancy supplymechanism is the supply efficiency, and higher contribution to the agricultural growth,also more contribution to the development of agriculture as well as farmers’ income isthe better mechanism. Based on input-output theory, paper analyzes empiricallyChina’s water conservancy development and investment forms and explores theoperating mechanism from the perspective of economic efficiency. The results showthat, currently China’s operational efficiency of Irrigation and Water Conservancy ofrural areas is low, as well as the significant regional gap, of which the eastern regionis the highest and the western is the lowest; the low operational efficiency of centralregion of rural areas’ Irrigation and Water Conservancy is mainly due to the lack ofpure technical efficiency, but the scale of inefficiency to the eastern. The permanentincome has a certain role in promoting the Farmland Water Efficiency, but directfinancial subsidies do not have this role. Changing the way of government’s participation in Farmland and Water Conservancy in the construction or management,as well as Farmland and Water Conservancy supply path, are important approaches tosolve this problem.The better way that the government participating in the Farmland WaterConservancy is government participating in and organizing major persons to buildand manage the large and medium-sized water conservancy, but the government justinvests the small-sized Farmland Water Conservancy and let the rural areasself-organize and manage. In the supply path, currently the country should focus onthese five indicators: Effective Irrigation Area, Harvest Area of Stable，Area of Waterand Soil Erosion Control, Storage Capacity of Small Reservoir and Effective Laborsfor the whole country. In the view of district, the eastern part should focus on theindicator of Area of Water and Soil Erosion Control, Effective Irrigation Area,Storage Capacity of Small Reservoir and Effective Labors; and Harvest Area ofStable, Capacity of Medium-sized Reservoir for the central regions, as well asEffective Irrigation Area, Irrigated Area of More than Ten Thousand Mu and EffectiveLabors for the western regions. To construct the effective supply mechanism for thelarge and medium-sized water conservancy as well as small Farmland WaterConservancy.
