"The Corruption Index is an indicator used to measure the extent of government corruption in various countries, also known as the "Global Corruption Perceptions Index" (Corruption Perceptions Index, CPI). The index is released annually by the international non-governmental organization "Transparency International" (Transparency International) , which aims to assess the extent of government corruption in various countries through investigation and analysis in various fields.

The corruption index is usually evaluated using a score from 0 to 100, where the higher the score, the lower the degree of corruption in the government of the country, and vice versa, the higher the degree of corruption. The specific evaluation method is to obtain a relatively accurate evaluation result through the investigation of various aspects such as government agencies, enterprises, media and civil society, and using various data sources and methods.

The evaluation results of the corruption index have a certain influence and reference value in the world. On the one hand, corruption is a global problem that will have a negative impact on national political stability, economic development, and social equity. Therefore, the international community is very concerned about corruption, and the corruption index can provide reference for governments and help them formulate anti-corruption policies and measures. On the other hand, the corruption index can also affect international investment and trade decisions, because investors and companies often consider factors such as the degree of corruption when choosing countries and partners.

It should be noted that although the corruption index is an important assessment tool, it also has certain limitations. On the one hand, the evaluation results only represent a perception and cognition, and do not necessarily reflect the actual corruption situation; on the other hand, the differences in culture, political system and economic development level of different countries and regions will also affect the evaluation results of the corruption index . Therefore, the evaluation results need to be comprehensively analyzed in light of the specific situation, and the corruption index of a country cannot be evaluated solely by the ranking of the corruption index.
