We use large survey data sets of firms provided by the World Bank for China, India, and Brazil—Investment Climate Surveys—to address the important question: what determines the locational choice of firms among cities in these countries. We find that capital cities in all countries are attractive for firms to locate. In India and China, labour-intensive firms tend not to locate in mid-sized or l...

With the rapid economic growth and development, the problem of environmental pollution in China’s cities is becoming increasingly serious, and environmental pollution takes on a regional difference. There is, however, little comprehensive evaluation on the environmental performance and the regional difference of strictly-environmental-monitored cities in China. In this paper, the environmental ...
