With the implementation of the uneven development strategy, Jiangsu has witnessed a widening dichotomy in levels of socio economic development: southeast showing rapid improvement and north showing little improvement, particularly in rural areas. Based on factor analysis, it is argued that foreign investment, agricultural productivity, the character of regional economic structures, and the level of urbanization all contribute in varying ways to the inequalities in levels of socio economic development in different regions of Jiangsu. According to the levels of socio economic development, eleven regions are categorized into three groups.展开更多

The data of this study were based on the database of Wo S. ＂Diabetic retinopathy＂ was used as the keywords to search the Wo S database.RESULTS： The United States ranked first in the DR research with 1840 publications and 24.38% of the world production followed by England and Japan. Besides, the most productive country was Iceland. A high correlation was found between number of publications and 2014 gross domestic product（ GDP） values of 81 countries（r =0.800, P 〈0.001）. We found a significant correlation between number of publications and Human Development Index（HDI）（r =0.645, P =0.001）. There is a moderate correlation between people with diabetes and number of DR publications for 81 countries（r =0.514, P 〈0.01）. It could be analysed that estimated publication number with DR title will be 445 according to the regression curve constituted with cubic model in 2015（R2=1.000）.CONCLUSION： More DR studies have been published in developed countries, DR and other complications of diabetes have gradually increased in developing countries over recent decades. It can be expected that the number of DR studies will gradually increase in developing countries.展开更多
