This paper investigates the relationship between economic opportunities and official corruption in China. We construct a cross-province sample of corrupted officials to analyse the effects on official corruption of mineral reserve, coal production, real estate and road construction, while including control variables such as population, GDP per capita, economic growth rate, private assets, provincial government capacity, fiscal transparency and distance of the province from Beijing. Spanning from December 2012 to November 2015, our sample contains 526 high-level government officials who worked in various provinces in China. We find through multivariate regression that economic opportunities represented by coal, minerals, real estate and road construction all have a positive and significant effect on official corruption in China at the levels of provincial department director or deputy director; meanwhile, capacity of political extraction, road construction and coal production are better indicators of official corruption at the level of governor or deputy governor.
