Abstract: Using ESDA spatial analysis, this paper researches the spatial pattern evolution and characteristics of per capita net income of farmers in the Yangtze River Delta counties since 1989. The results show that: (1) the absolute difference in per capita net income of farmers is gradually widening, while the relative difference is decreasing with periodic fluctuations; (2)the level of per capita net income of farmers has a strong positive spatial correlation, and the regions with similar income levels have a spatial agglomeration; (3)the growth pattern of per capita net income is proved to be more instable, where its growth hot spots and cold spots switch frequently in their geographical locations, showing the existence of transition phenomenon. Apart from subordinate revenue growth cold spots, trend of spatial concentration enhanced while tendency of random distribution weakened in other growth type areas. Finally, this paper reaches some conclusions and conducts some corresponding discussions. Besides, related suggestions are given to narrow regional differences in Yangtze River Delta counties and promote the regional coordinated development.
