Together, 工业 (gōngyè) is the standard word for “industry.” The addition of 4.0 (sì diǎn líng) directly mirrors the English/German term “Industry 4.0,” signifying the fourth major industrial epoch.
While the term “Industrie 4.0” originated in Germany, 工业4.0 has taken on a unique and profound significance in China. It is deeply intertwined with the national ambition for technological self-reliance and economic transformation. For decades, China was known as the “world's factory,” excelling at low-cost, labor-intensive manufacturing. 工业4.0 represents the strategic pivot away from this model. It's the engine for the “Made in China 2025” (中国制造2025) initiative, a state-led plan to upgrade China's manufacturing capabilities in ten key sectors, including robotics, aerospace, and electric vehicles. A key difference from the West is the top-down, state-driven approach. While in America or Europe, Industry 4.0 adoption is often led by individual companies seeking a competitive edge, in China, it's a national mission. The government provides massive subsidies, sets clear policy goals, and encourages state-owned and private enterprises alike to invest heavily in smart manufacturing. This makes 工业4.0 not just a business strategy but a reflection of a national value: achieving “technological rejuvenation” (科技复兴) and securing a leading position in the global economy of the future.
工业4.0 is a formal and technical term. You won't hear it in casual chats about the weather, but it's ubiquitous in specific professional contexts.
