Research on Financial Performance Evaluation of the Steel Industry—Based on Principal Component Analysis

摘要: 钢铁行业是国民经济的重要基础产业，其上市公司的财务绩效直接反映了行业的发展质量与竞争能力。本文以沪深A股33家钢铁行业上市公司为研究对象，选取2025年度财务数据，从盈利能力、偿债能力、营运能力和发展能力四个维度构建财务绩效评价指标体系，运用主成分分析法进行综合评价。研究结果表明，主成分分析能够将多个财务指标有效降维，提取出反映综合财务能力、经营规模、收益质量和发展能力的关键主成分。本文旨在为钢铁企业优化经营策略、提升财务绩效提供参考，也为投资者和管理者提供决策依据。

Abstract: The steel industry is a crucial foundation of the national economy, and the financial performance of its listed companies directly reflects the industry’s development quality and competitiveness. This study takes 33 listed steel companies on the Shanghai and Shenzhen A-share markets as the research object, selecting their 2025 financial data. A financial performance evaluation index system is constructed from four dimensions: profitability, solvency, operating capacity, and growth capacity. Principal component analysis (PCA) is employed for comprehensive evaluation. The results show that PCA can effectively reduce the dimensionality of multiple financial indicators and extract key principal components that reflect comprehensive financial capability, operating scale, earnings quality, and growth capacity. This study aims to provide references for steel enterprises to optimize their business strategies and improve financial performance, as well as to offer decision-making basis for investors and managers.
