Abstract:

This paper aims to explore the heterogeneous pattern, evolving characteristics, and driving mechanism of provincial water transfer from agriculture to non-agriculture from 2003 to 2015 in China, by methods of spatio-temporal cluster, the shifting gravity center and its decomposition and panel quantile regression. The results show that: (1) The spatial divergence of water transfer from agriculture to non-agriculture is obvious, which is gradually decreasing from the southeast coast to the northwest inland, and the divergence in northern provinces are lower than that in southern regions. (2) The shifting gravity center of water transfer from agriculture to non-agriculture has changed greatly. the gravity center of water transfer from agriculture to non-agriculture moves southwestward between 2003 and 2008, which is propelled by the engines of Chongqing, Qinghai and Yunnan; While the gravity center of water transfer from agriculture to non-agriculture shifts to the northeast from 2008 to 2015, which is resulted from both the falling speed of water transfer from agriculture to non-agriculture in the western provinces and the joint promotion of water transfer from agriculture to non-agriculture in Liaoning, Jilin and Beijing. (3) The change of regional industrial structure, the improvement of marketization level, per capita water resources and the improvement of ecological environment are the main driving factors of water transfer from agriculture to non-agriculture. The improvement of the comparative benefit of water resources utilization, the level of economic development and population size are the main constraints of the trsnsfer, while the urbanization level and the effective rate of agricultural irrigation exert reverse impacts on different levels of water transfer from agriculture to non-agriculture in different periods of time.
