Chinese Manufacturing Firms Distribution at 0.01° Grid Scale, 2015 and 2019

China's Gridded Manufacturing Dataset maps the distribution of manufacturing firms across China at a 0.01° latitude by 0.01° longitude scale. It includes 4.40 million firms in 2015 and 6.01 million in 2019, classified into seven categories. The dataset was built by Chenjing Fan of Nanjing Forestry University using a machine learning-based point-of-interest classification method.

Use Cases

• Characterizing spatial patterns of manufacturing firm distribution based on the high-resolution gridded data.
• Analyzing temporal changes in manufacturing industry development between 2015 and 2019.
• Revealing mechanisms underlying regional economic policy changes based on firm location and type data.
• Mapping the geographical concentration of specific manufacturing categories across China.

Strengths

• High spatial resolution at a 0.01° by 0.01° grid scale, addressing limitations of previous low-resolution data.
• Includes a large number of records: 4.40 million firms for 2015 and 6.01 million for 2019.
• Firms are classified into seven distinct manufacturing categories.
• Covers two time points (2015 and 2019), enabling temporal analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified beyond 2019.
• Data may reflect geographic or temporal bias inherent to the source point-of-interest data and classification method.
