宗教文化影响指数Religious Cultural Impact Index

Religious culture is an important part of Chinese culture. Buddhism was introduced during the Eastern Han dynasty, Daoism originated natively, Islam was introduced during the Tang and Song dynasties, and Catholicism and Protestantism entered China successively from the late Ming and early Qing dynasties, forming a cultural landscape of diverse religions coexisting, each with its own characteristics. Mr. Fei Xiaotong summarized the structure of Chinese culture as "the unity in diversity of the Chinese nation," and religious culture is an inseparable strand of it—scripture translation, statuary, temples, music, folk customs, and charity have all been sedimented into the common heritage of Chinese civilization.

This list is positioned as a "Religious Culture Influence Index" rather than a ranking of religions. It measures only one neutral dimension—historical and cultural contribution (scriptures, thought, art, architecture, music, folk customs, charity and public welfare, and cultural transmission)—and does not measure the "truth of faith" of any religion, nor does it evaluate the superiority or inferiority of any religion or denomination. Article 36 of the Constitution of the People's Republic of China guarantees citizens' freedom of religious belief, and all religions are equal before the law; this list respects and upholds that principle.

This list likewise does not concern religious policy, church-state relations, or religious administration affairs; it merely presents, objectively and neutrally, the cultural deposits left by each religion/denomination over the long course of history and their contemporary transmission. Evaluation results: religions/denominations such as Chan Buddhism, Pure Land Buddhism, Tibetan Buddhism, Islam (Sunni), and Christianity (Protestant) have deep cultural deposits and active transmission in contributions such as scriptures, thought, art, architecture, and charity. The level of the index reflects only the volume and activity of "cultural influence," and by no means represents the standing of any religion in value or status. The data are mainly publicly known approximations, marked "subject to official data," permanently free and public, and for research and reference only.

The object of this index is the neutral fact of "cultural influence," not religion itself. Its rationale is as follows:

This index uses a four-dimensional weighted summation model. Each indicator is first mapped to the [0,1] interval via min-max standardization, the adherent scale in the Scale dimension is log-transformed (a wide-ranging indicator to avoid leading dominance), and then weighted:

Where: Quality = historical and cultural contribution (scriptures/thought/art/architecture); Innovation = cultural transmission and contemporary development; Contribution = social welfare, charity, cultural transmission, and social harmony. The four weights sum to 1.00, with Quality carrying the highest weight (0.30) because it fits the theme of "cultural influence"; Contribution's 0.25 reflects the distinctive CPPPS dimension (charity and harmony); Scale is 0.25 and Innovation is 0.20.

This list covers 13 items across China's five major religions and their main denominations/schools: 8 items for Buddhism (Chan, Pure Land, Tiantai, Huayan, Consciousness-Only, Vinaya, Tibetan Buddhism, and Theravada Buddhism), 2 items for Daoism (Quanzhen and Zhengyi), 1 item for Islam (Sunni, the main body of Chinese Islam), 1 item for Catholicism, and 1 item for Protestantism. The six Chinese Buddhist schools are presented by lineage/practice method, and adherents may practice across schools, so the adherent counts for each school are rough estimates used only as a reference for the Scale dimension.

The indices for adherent scale, historical years, historical and cultural contribution, transmission and development, and charity are all publicly known approximations (referring to religious scriptures, works of religious history research, and public materials), marked "subject to official data." Religious culture is subjective and inexhaustible, and the adherents of various Chinese Buddhist schools overlap and are hard to separate precisely, so the approximations contain errors; this index reflects only the single neutral dimension of "historical and cultural contribution," is by no means equivalent to a value judgment on religion itself, and is for research and reference only.
