Abstract: The study of club convergence of water resources utilization efficiency will help the government carry out regional water resource management more targetedly and focus on areas that have long been “trapped” in low efficiency. The paper studied the phenomenon of club convergence of total water use efficiency, agricultural water use efficiency and industrial water use efficiency in the 31 provinces of the mainland of China during 2003-2015 using extended Markov chain and extended spatial Markov chain model based on the Quah (1997) distribution dynamics analysis framework. Firstly, we examined the club convergence of three types of water efficiency. Then, we measured the extents of club convergence based on the constructed club convergence index. Finally, the phenomena of three types of club convergence were explained from a spatial point of view. The results show that: 1) There are a phenomenon of club convergence in the three types of water use efficiency which will be eased with time, but the phenomenon is still evident. For example, the probability that area with low industrial water use efficiency remained low after five years is 0.808, while that high-level remained high after five years is 0.918. Therefore, the coordination of regional water resources efficiency needs to be strengthened. 2) The industrial water use efficiency is the highest in the degree of club convergence, followed by the total water use efficiency, and the agricultural water efficiency is the lowest. The degree of differential curing of industrial water use efficiency is the most serious one that some areas have remained at low level for a long time and are caught in a “low level trap”, which should be taken seriously by the government. 3) The phenomenon of club convergence is influenced by spatial factors. On one hand, the adjacent areas with different water use efficiency have a certain influence on the water use efficiency in a region that high level adjacent areas have positive impact and low level adjacent areas have negative impact. On the other hand, there are spatial agglomerations of high and low level clubs, so there is spatial spillover effect inside clubs. However, the positive spillover effect in high level clubs is much larger than that in low level clubs, which makes the difference between high and low level clubs widen further so as to promote the phenomenon of club convergence. This is particularly evident in the club convergence of industrial water use efficiency in China.

Key words: club convergence, club convergence index, Markov chain model, water resources utilization efficiency
