ポーランドの家計予算調査を用い、エネルギー支出の長期動向と多次元エネルギー貧困（EP）指数を分析。k-meansクラスタリングで電気・ガス型と地域熱供給型の2大支出プロファイルを識別し、ロジスティック回帰でEPの決定要因を特定した。EPは低所得単独ではなく経済・社会・住居要因の相互作用から生じ、高学歴や労働市場参加がリスクを低減、非労働所得依存や固形燃料暖房が増大させる。支出割合の低下は厚生改善を意味せず、エネルギー効率投資や低炭素暖房と社会保護の統合政策を提言する。
English
Using Poland's Household Budget Survey, this study analyzes long-term energy expenditure trends and constructs a multidimensional energy poverty (EP) index. K-means clustering identifies two dominant expenditure profiles (electricity–gas and district heating), while logistic regression shows EP stems from interacting economic, social, and housing factors—not low income alone. Higher education and labor participation reduce EP risk; non-labor income and solid-fuel heating raise it. Declining expenditure shares do not signal improved welfare, supporting integrated social protection with energy-efficiency and low-carbon heating investment.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈では、カーボンプライシングや暖房電化の進展が家計負担とエネルギー貧困をどう左右するかという論点に直結する。SSBJ開示や企業のトランジション戦略においても、公正な移行（just transition）の社会的側面をどう扱うかは統合報告書での重要課題となりつつある。
In the global GX context
As CSRD/ISSB disclosure and transition finance increasingly demand social safeguards, this paper offers empirical grounding for the 'just transition' dimension of climate policy. It shows expenditure-based metrics understate energy poverty, relevant to EU energy-crisis policy and to disclosure frameworks weighing affordability impacts of decarbonization.
👥 読者別の含意
🔬研究者:多次元EP指数の構築手法とleave-one-dimension-out感度分析は、エネルギー貧困研究の指標設計に有用な方法論的参照点となる。
🏢実務担当者:住宅のエネルギー効率化・低炭素暖房投資が家計負担軽減と社会的リスク低減に資することを、トランジション計画の根拠として活用できる。
🏛政策担当者:支出割合指標だけではエネルギー貧困を過小評価するため、社会保護と住宅改修・低炭素暖房投資を組み合わせた統合政策設計が求められる。
📄 Abstract（原文）
Rising energy prices, the recent energy crisis, and the low-carbon transition have intensified concerns about household energy affordability and exposed the limitations of expenditure-based measures of energy poverty. This study provides an integrated assessment of household energy expenditures and multidimensional energy poverty in Poland, combining long-term expenditure trends, energy consumption profiles, and socioeconomic determinants. Using nationally representative data from the Polish Household Budget Survey (Statistics Poland), we apply trend and elasticity analysis, k-means cluster analysis, and logistic regression to identify expenditure patterns, construct a multidimensional Energy Poverty (EP) index, and determine the factors associated with energy poverty risk. Cluster analysis reveals two dominant expenditure profiles (electricity–gas and district heating), differentiated by place of residence, income, and education; a small solid-fuel profile is identifiable only in 2023. Regression results show that energy poverty arises from the interaction of economic, social, and housing-related factors rather than low income alone. Higher educational attainment and labor market participation significantly reduce the likelihood of multidimensional energy poverty, whereas reliance on non-labor income and solid-fuel heating substantially increases it; disposable income declines monotonically with EP severity. A leave-one-dimension-out sensitivity analysis indicates that these associations are not artifacts of the index’s construction. A declining expenditure share should not be interpreted as improving welfare, as expenditure-based indicators may underestimate energy poverty by overlooking material deprivation and housing conditions. The findings support integrated policies combining targeted social protection with investments in residential energy efficiency, housing modernization, and low-carbon heating technologies.
