'商业' (shāng yè) is a compound noun meaning 'business' or 'commerce'—the broad activity of buying, selling, and trading goods and services. The first character, 商 (shāng), originally referred to merchants or trade; the second, 业 (yè), means 'profession', 'occupation', or 'enterprise'. Together, they denote the organized system of commercial activity, whether at local markets or multinational corporations.

This term is formal and neutral in register, commonly used in news, official documents, business education, and economic discussions. It appears in phrases like '商业计划' (business plan), '商业区' (commercial district), and '电子商务' (e-commerce). Unlike colloquial terms such as '生意' (shēng yi), which often implies small-scale or informal trade, '商业' emphasizes structure, scale, and institutional context—not personal transactions or casual ventures.
