Income Disparity, Social Network And The Supply Effectiveness Of Irrigation Facilities

The supply level of irrigation facilities is related to the agricultural production ability and food security, and it is one of the important tasks to solve the problem of “agriculture, rural areas and farmers”. There are some problems, such as inadequate investment, aged facilities and disrepair, still exist in the construction, management and maintenance of irrigation facilities. Investigating the supply effectiveness of irrigation facilities will provide some means of use for reference to solve these problems. Rural households are the direct users of irrigation facilities, and their evaluation is the most direct. So, the article based on the perspective of rural households, is to explore the supply effectiveness of irrigation facilities.However, there are obvious differences between rural households, especially in the aspect of economic income and individual relationship network. The income disparity will affect the farmers` investment intention and demand for irrigation facilities. The social network will affect the rural households` supply participation and use feeling, thus affecting their evaluation. Therefore, the article studies the supply effectiveness of irrigation facilities by viewing income gap and social network.First, the article discussed the basic information of Chinese irrigation facilities by 2014,including the supply scale, the main body and the type. Second, using micro data which was obtained from the survey in Shannxi, Henan and Ningxia, the article analysed the basic situation of the sample area. The main content included the construction level, management and maintenance. Finally, built the Ordered Probit model, analysed the effects of income disparity and social network on the irrigation facilities supply, and did endogenous and robustness test.The conclusions are the following:( 1) The investment in Chinese irrigation facilities increases year by year, and the investors mainly are the central and local government. At present, the rural households thought the supply effectiveness of irrigation facilities is improved and their needs are basically met. But the government should make more investment in the irrigation facilitiesand strengthen the supporting facilities, especially to ensure “the last kilometer”. The management and maintenance are not in place. The main body is not clear, the full-time staff are lacked, and the treatment is insecure. The capital source channel is narrow. The organization and regulations are incomplete.(2)Both the income disparity between rural residents and the rural households` social network have a significant positive impact on the supply effectiveness of irrigation facilities.But with the increase of social network, the positive influence of income disparity decreased.As the income increases, the demand for irrigation facilities increases, also, the ability to pay improves. Thus, the supply effectiveness of irrigation facilities becomes better. As the social network expands, the information communication is more convenient and people supervise each other. So the effectiveness will be improved. However, with the social network growing,the feelings which is brought by income disparity will fade out, so that the positive influence decreases.( 3) The people who is a party member or whose family owned irrigation ancillary facilities have a good effect on the supply effectiveness, while the families with children in school have a significant negative effect. the age, household income and the cultivated area have no significant effect on the supply effect.
