破繭重「光」：友達、群創與光電產業之比較分析

Abstract

中文摘要 面板產業為現代資訊與電子科技的重要核心，廣泛應用於電視、電腦、智 慧型手機、車用顯示器及醫療設備等領域，其發展不僅影響科技產業供應鏈， 也與國家經濟成長、出口表現及就業市場密切相關，具有研究價值。然而，面 板產業多年受景氣循環影響，使產業面臨高度競爭與轉型之經營壓力。因此， 本研究以群創光電與友達光電為研究對象，探討兩家公司在財務與營運上的表 現與差異，進一步了解台灣光電面板產業未來的發展方向與可能面臨的挑戰， 同時，也希望能提供投資人具參考價值的資訊。 本研究採用共同比分析、變動百分比分析及比率分析等方法進行研究，並 結合資產負債表與綜合損益表進行整體評估。同時，亦以光電面板產業平均作 為參照基準，以評估兩家公司之相對競爭力與財務韌性。 基於上述之研究方法，財務報表分析之結果顯示群創在短期償債能力與財 務結構方面相對穩定，財務風險較低；友達則在營運效率與存貨管理方面表現 較佳，但負債壓力與財務槓桿較高。整體而言，兩家公司皆受到面板產業景氣 循環與市場需求波動影響，獲利表現具有高度波動性，因此近年積極投入車用 顯示、智慧移動、半導體封裝及高階顯示技術等高附加價值領域，以降低對傳 統消費性面板市場的依賴。投資者進行投資決策時仍應考量當時景氣循環變 化，並持續追蹤兩家公司在財務上的後續表現。

Abstract The panel industry is a core component of modern information and electronic technology, with extensive applications in televisions, computers, smartphones, automotive displays, and medical equipment. Its development not only impacts the technology supply chain, but is also closely related to national economic growth, export performance, and employment, making it a valuable subject for research. However, the panel industry has long been influenced by economic cycles, leading to intense competition and significant pressure for transformation. Therefore, this study takes Innolux Corporation and AUO Corporation as the research subjects to examine and compare their financial and operational performance. The study further aims to explore the future development trends and potential challenges of Taiwan’s optoelectronic panel industry, while also providing valuable information for investors. This study adopts common-size analysis, trend (percentage change) analysis, and ratio analysis as the main research methods, and integrates the balance sheet and the statement of comprehensive income for an overall evaluation. In addition, the industry average of the optoelectronic panel sector is used as a benchmark to assess the relative competitiveness and financial resilience of the two companies. Based on the above methodologies, the results of the financial statement analysis indicate that Innolux demonstrates relatively stable short-term solvency and financial structure, with lower financial risk. In contrast, AUO shows better performance in terms of operational efficiency and inventory management, but faces higher debt pressure and financial leverage. Overall, both companies are significantly affected by the cyclical nature of the panel industry and fluctuations in market demand, resulting in highly volatile profitability. Therefore, in recent years, both companies have actively invested in high value-added sectors such as automotive displays, smart mobility, semiconductor packaging, and advanced display technologies, in order to reduce their reliance on traditional consumer panel markets. When making investment decisions, investors should consider the current stage of the economic cycle and continuously monitor the subsequent financial performance of both companies.
