1、 The significance of conducting research on the Global Political Party Influence Index

It emphasizes that in the context of multiple global challenges and crises, political parties are an important force leading the modernization process, and measuring their influence is crucial for political science theory and applied research. Chinese scholars mainly use qualitative methods to study foreign political parties, focusing on domestic political parties in Europe, America, and some developing countries. There is a two-dimensional distinction between mature democratic countries and emerging southern countries, and between traditional and emerging political parties. Beijing Foreign Studies University utilizes its language and platform advantages to build a "Global Political Party Database", which includes effective political parties from 116 Western style democratic election system countries worldwide. The goal is to construct a global political party influence indicator system, enrich the understanding of global political parties, and be of great significance for understanding international cooperation and conflicts, predicting domestic and foreign affairs trends, assessing political change risks, and exploring new models of global governance.

2、 Construction of Indicator System for Global Political Party Influence Index

We have developed an indicator system for the Global Political Party Influence Index, covering three dimensions: elections, organization, and dissemination. The election dimension measures the influence of political parties through vote share and seat ratio; The organizational dimension focuses on the structure, program, members, leaders, and system of political parties; The communication dimension includes the influence of communication on social media. The evaluation workflow includes defining effective political parties, data collection, organization and standardization, as well as determining weighted indicators and synthesizing indices. The determination of evaluation index weights combines the subjective assignment of Analytic Hierarchy Process and the objective weights of CRITIC method to ensure the objectivity and rationality of the evaluation.

3、 Global Political Party Influence Assessment Results

The influence scores of 580 political parties worldwide were evaluated through algorithms, and it was found that the mean was 42.74, the variance was 329.84, and the distribution was skewed to the right, with most scores concentrated in the range of 20-60. There are 226 political parties with an influence score greater than 50, accounting for 38.97% of the total. Ten political parties, including the Cambodian People's Labour Party, ranked among the top ten globally with scores above 75. These parties have strong competitiveness in parliamentary elections, significant organizational influence, and active social media. The political parties with strong influence are mainly distributed in the "global South" countries, with the highest number in Latin America. The average score of global political party election ability is 17.53, with a variance of 335.21, indicating significant differences between political parties. The Cambodian People's Party has the strongest electoral ability, scoring 93.92. Most political parties have weak abilities in parliamentary elections, with 287 parties scoring below 10 points. The average score for global political party organizational ability is 71.73, with a variance of 1110.99. 295 political parties have three major organizational factors: national political parties, clear election platforms, and regular party congresses. The organizational ability score of 41 political parties is 0. The average score for global political party communication ability is 46.8, with a standard deviation of 377.07, indicating relatively small differences between political parties. The Cook Islands Party has the strongest dissemination ability, scoring 93.07. 71 political parties have a communication ability score of 0 and have not opened any social media accounts. The vast majority of political parties' social competence scores are concentrated between 50 and 60.

4、 Conclusion and Discussion: Global Party Politics in the Era of Party Dominance

Discussed the diversification and complexity of political party influence in the context of global democratic political development. The study collected data from 677 valid political parties worldwide and found an average of 5.84 valid political parties per country, indicating the activity of political party organizations. The study evaluates the influence of global political parties from three dimensions: politics, organization, and communication, and finds that some political parties have super strong influence domestically, and these parties are mostly concentrated in the emerging "global south" region. The study provides a new observational perspective and comparative dimension for global party politics research, highlighting the new characteristics of party politics in Asia, Africa, and Latin America. At the same time, the study also pointed out the difficulties in unifying cross linguistic, cross-cultural, cross institutional, and comparative dimensions, as well as the limited number of indicators, which require further efforts and exploration to more comprehensively reflect the influence of political parties.
