Abstract: Domestic and foreign academics have increasingly enriched the research on party centrism. However, from the perspective of comparison between China and foreign countries, there are still some theoretical issues that need to be studied urgently. In the face of increasingly complex political party activities at home and abroad and their influence, we need to think deeply about whether political parties are a problem in the 21st century, or a solution to the problem? This question is important at both theoretical and practical levels. At the theoretical level, party centrism has shown completely different cognitive forms in different countries, which is manifested in the differences in the dimensions of party positioning, party nature, and the theoretical roots of party centrism. At the practical level, party politics in some countries has resulted in vicious party disputes, social tearing and political decay; in our country, the leadership of the Communist Party of my country has become the key for the country to resist risks and challenges, the people to create a better life, and the nation to achieve great rejuvenation. Fundamental security and political foundation. This paper makes a systematic comparison between China and foreign countries on party centralism, especially focusing on comparative research from the aspects of driving force, party relations, party building logic, and party building methods. Our research believes that the value of political parties in different countries has emerged huge divisions, and the great diversion in the 21st century is not manifested in differences in political systems, but in differences in political organizations.
