The work aims to analyze and summarize the characteristics of industrial heritage after the founding of the People's Republic of China to guide the protection and reuse of Chinese industrial heritage. The industrial heritage in the cultural heritage lists issued by various departments of China was integrated and summarized. From the perspectives of spatial distribution and industrial distribution of industrial heritage, the provincial distribution, aggregation, city characteristics, industry types, and scale characteristics of industrial heritage after the founding of the People's Republic of China were analyzed and factors influencing the formation were summarized. The industrial heritage after the founding of the People's Republic of China was mainly distributed in the central China and north, southwest and northeast of China. In terms of space, it presented an aggregated distribution in space, generally characterized by macroscopic uniformity and microscopic aggregation. There were a large number of industrial heritages after the founding of the People's Republic China distributed in smaller cities. In terms of industry characteristics, the distribution was regional and heavy industry occupied an absolute quantitative advantage. Finally, the industrial heritage after the founding of the People's Republic of China has many characteristics worth exploring. Analyzing and summarizing these characteristics is of great significance to China's stock development, industrial transformation, cultural innovation and other current social development issues.
