中国282个地级城市2004~2020年人口集聚、经济集聚、产业集聚和绿色经济效率数据集

本数据集聚焦中国 282 个地级城市，时间跨度为 2004~2020 年，核心变量包括绿色经济效率（gee）、人口集聚（pop）、经济集聚（eco）、产业集聚（ind），并含更换测算方式后的集聚指标（npop、neco、nind），同时涵盖城市基础设施（infra）、政府重视程度（gover）、对外开放（open）等影响因素，以及铁路通达度（rail）、地形起伏度（tu）等工具变量和区域（area）、城市规模（size）、省份（pro）划分信息。缺失数据采用上下均值填补，数据量 364.17KB，仅 1 个文件，以 CC0 协议开放获取，可支撑城市集聚机制与绿色经济效率关系等相关研究。This dataset focuses on 282 prefecture-level cities in China, spanning the period from 2004 to 2020. Its core variables include green economic efficiency (gee), population agglomeration (pop), economic agglomeration (eco) and industrial agglomeration (ind), as well as agglomeration indicators (npop, neco, nind) calculated via alternative measurement methods. It also covers control factors such as urban infrastructure (infra), government attention (gover) and opening-up (open), instrumental variables including railway accessibility (rail) and terrain relief (tu), as well as division information for regions (area), city size (size) and provinces (pro). Missing data are imputed using the mean of adjacent upper and lower values. The dataset has a total size of 364.17 KB, stored as a single file, and is openly accessible under the CC0 license. It can support relevant academic studies, such as those exploring the relationship between urban agglomeration mechanisms and green economic efficiency.
