Data and code for "An empirical study on air transport promoting the coordinated regional economic development: A perspective of spatial interaction"

This panel dataset supports the empirical analysis in the paper An empirical study on air transport promoting the coordinated regional economic development: A perspective of spatial interaction. It covers 21 undirected region-pairs formed by China’s 7 official civil aviation administrative regions over 2008–2024, with 357 balanced region-pair-year observations. The dataset includes all variables used in the study: a composite Coordinated Regional Economic Development (CRED) index and its sub-dimensions, inter-regional air transport volume (core independent variable), mechanism variables (spatial interaction, factor endowment gaps), and a full set of control variables covering other transportation modes, regional economic attributes and resource endowments. Raw data are sourced from the China Civil Aviation Statistical Yearbook, National Bureau of Statistics of China, EPS China Macroeconomic Database, and Amap API. The accompanying Stata code enables full replication of all empirical analyses in the paper, including baseline regressions, endogeneity tests, robustness checks, mechanism analyses, and heterogeneity tests.本面板数据集（panel dataset）为论文《航空运输促进区域经济协调发展的实证研究——基于空间互动视角》中的实证分析提供支撑。其涵盖2008年至2024年由中国7个官方民航行政区形成的21组无向区域对，共计357组平衡区域对-年度观测样本。 该数据集包含本研究使用的全部变量：综合区域经济协调发展（Coordinated Regional Economic Development, CRED）指数及其子维度、区域间航空运输量（核心自变量）、机制变量（空间互动、要素禀赋差距），以及覆盖其他运输方式、区域经济属性与资源禀赋的全套控制变量。原始数据来源于《中国民航统计年鉴》、国家统计局（National Bureau of Statistics of China）、EPS中国宏观经济数据库以及Amap API。 随附的Stata代码可完整复现论文中的所有实证分析，包括基准回归、内生性检验、稳健性检验、机制分析与异质性检验。
