Neijuan, often translated as involution, is a Chinese term describing a situation where increasing effort and competition within a system fail to produce corresponding improvements in output or efficiency. The term, composed of characters meaning "inside" and "curling," originally referred to complex social and economic dynamics but has recently gained prominence as a cultural phenomenon in China.

Historically, the concept of involution was introduced by American anthropologists Alexander Goldenweiser and Clifford Geertz to describe processes where societies or agricultural systems become more complex internally without evolving or increasing productivity. In China, the term has evolved to capture the intense competition in education, labor markets, and business sectors that leads to diminishing returns despite escalating input.

Since 2020, neijuan has become a widespread internet slang term in mainland China, symbolizing a culture of relentless competition where individuals feel trapped in a cycle of overwork and stress with little reward. This sentiment resonates strongly among millennials and Generation Z, especially students and young professionals facing pressures in elite universities and the tech industry.

The phenomenon extends to parental behavior, where middle-class families invest heavily in their children’s education from an early age to maintain social standing amid fierce competition. This has led to early specialization in subjects and extracurricular activities, high real estate prices near quality schools, and significant spending on tutoring.

In the workplace, neijuan is linked to the 996 work culture—working from 9 a.m. to 9 p.m., six days a week—common in sectors like technology and finance. Despite labor laws, many workers report unpaid overtime and exploitative conditions. The intense competition and long hours contribute to widespread feelings of burnout and dissatisfaction.

The Chinese government has recognized neijuan as a macroeconomic concern, associating it with unhealthy market competition that drives deflation and economic inefficiencies. Efforts are underway to regulate private businesses and stabilize market conditions to address these issues.

Neijuan has also sparked social responses such as the "lying flat" (tangping) movement, where some young people choose to reject the relentless grind by lowering their ambitions and workload. While initially tolerated, this resistance has drawn criticism from state media concerned about social stability.

Overall, neijuan reflects broader challenges in China’s rapidly changing economy and society, highlighting the tensions between growth, competition, and individual well-being. It underscores the need for balanced policies and cultural shifts to address the pressures faced by younger generations and the middle class.
