Replication Data and Code for “Why Industrial Gas Prices Remained Elevated after Europe’s 2022 Energy Crisis: Evidence from Pre-crisis Russian Gas Dependence”

This dataset contains the processed analysis data and replication code supporting the manuscript “Why Industrial Gas Prices Remained Elevated after Europe’s 2022 Energy Crisis: Evidence from Pre-crisis Russian Gas Dependence.” The study examines industrial gas-price persistence across twelve European Union member states over 2015–2024, with particular attention to pre-crisis Russian gas dependence, supplier diversification, and the industrial–wholesale price wedge following the 2022 European energy crisis. The repository contains an annual country panel (120 country-year observations), a semiannual panel used for the difference-in-differences and event-study analyses (240 potential observations; 239 usable observations), the Python replication script for the econometric analyses and robustness checks, the companion script for the calibrated simulation, and a README describing the files and reproduction procedure. The processed panels were constructed by the authors from publicly available Eurostat, IMF/FRED, and European Central Bank data. The replication code reproduces the principal fixed-effects estimates, difference-in-differences results, event-study estimates, robustness checks, supplementary analyses, and the calibrated simulation reported in the manuscript and supplementary materials. The underlying source data remain available from their original public providers and are cited in the manuscript.本数据集包含支撑学术论文《2022年欧洲能源危机后工业天然气价格为何仍居高不下：来自危机前俄罗斯天然气依赖度的证据》的经处理分析数据集与复现代码。本研究考察了2015-2024年间欧盟12个成员国的工业天然气价格持续性，重点关注危机前俄罗斯天然气依赖度、供应商多元化，以及2022年欧洲能源危机后的工业-批发价格价差。 本数据仓库包含年度国家面板数据（共120组国家-年份观测值）、用于双重差分（difference-in-differences）与事件研究法（event-study）分析的半年度面板数据（潜在观测值240组，有效观测值239组）、用于计量经济学分析与稳健性检验的Python复现脚本、用于校准模拟的配套脚本，以及一份README说明文件，用于介绍各文件内容与复现流程。 本研究的经处理面板数据由作者从公开可得的欧盟统计局（Eurostat）、国际货币基金组织/联邦储备经济数据库（IMF/FRED）以及欧洲中央银行（European Central Bank）的数据构建而来。本复现代码可复现论文手稿及补充材料中报告的核心固定效应估计、双重差分结果、事件研究法估计、稳健性检验、补充分析以及校准模拟结果。原始源数据仍可从其原始公开提供商获取，并已在论文中注明引用来源。
