Abstract: This paper reviews the quantitative studies on corruption and anti-corruption in China since the 18th National Congress of the Communist Party of China and finds that the definition of corruption is controversial, but it should not be generalized. There are two main methods to measure corruption, i.e., subjective evaluation and objective evaluation and the evaluation indexes are gradually developing from macro level to micro level. The characteristics of corruption are primarily reflected in the following ways. Corruption often occurs in the period of economic and social transformation; the political promotion and political cycle of officials have an impact on corruption and anti-corruption, and social culture influences the perception and behavior of corruption. In addition, corruption problems and their characteristics are different among the three types of subjects, including the public sector, state-owned enterprises and private enterprises. The impact of corruption on economic development is still controversial. Corruption is found to aggravate the imbalance of income distribution, while anti-corruption will significantly improve the public's perception of corruption and trust in the government. The anti-corruption campaign since the 18th National Congress of the Communist Party of China has a long-term positive effect on China's economic development and different anti-corruption measures have different impact mechanisms.
