Dataset for the paper "Evidence of Public Expenditure Spillovers in Mexico: Measuring Spatial Interactions Among Municipal Governments"

This panel dataset contains annual observations for 860 Mexican municipalities from 2000 to 2021. It includes fiscal, socioeconomic, political, and demographic variables used to study spatial interdependence in public expenditure. Key variables cover total expenditure, capital formation, subsidies, and service use (all in per capita terms), as well as explanatory and control variables such as household income, employment rate, political alignment, migration, federal transfers, taxation, population density, and reelection eligibility. The dataset also contains spatially lagged variables constructed using multiple spatial weight matrices (e.g., Queen contiguity, k-nearest neighbors with k=1 to 15) to facilitate spatial econometric analysis.本面板数据集（panel dataset）包含2000年至2021年间墨西哥860个市镇的年度观测数据。该数据集囊括财政、社会经济、政治及人口统计维度的各类变量，用于研究公共支出领域的空间依存性。核心变量涵盖总支出、资本形成、补贴及公共服务使用情况（所有指标均以人均口径核算），同时包含解释变量与控制变量，具体包括家庭收入、就业率、政治契合度、人口迁移、联邦转移支付、税收、人口密度以及连任资格等。此外，数据集还包含通过多种空间权重矩阵构建的空间滞后变量，例如皇后邻接（Queen contiguity）矩阵、k=1至15的k近邻（k-nearest neighbors）权重矩阵，以支撑空间计量经济学分析。
