摘要A small literature confirms the contagious effect of corruption, and finds that a lower national level of corruption is associated with a lower egional measure of corruption, as measured by the average level of corruption in one country’s neighbors. This study assumes that corruption is contagious, and uses the spatial statistics to carry out an empirical analysis. Using the spatial autocorrelation methodologies, including global Moran’s I and Getis-Ord’s local Gi, this study maps and compares spatial clusters for the control of corruption index form World Bank’s global governance indicators (World Governance Indicators, WGI) in different year. The results show that the corruption is indeed having significant contagion and strong cluster in Asia and Africa. The scope of corruption cluster in Asia only expands a little during the last decade. However, the corruption cluster is slowing beginning to spread to North and West African. In general, the strength of corruption cluster in Asian and Africa is getting higher. Secondly, corruption well-control cluster is found not obvious spreading in Europe and North America, even cluster is getting narrow. However, Australia and New Zealand form another significant integrity cluster. Although the strength of integrity cluster is changing little, the strength of integrity cluster in Czech Republic, the United Kingdom, Canada, and the United States is decreasing a little. On the contrary, the strength of integrity cluster in Australia and New Zealand are increasing.
