The term 'involution' usually describes an evolutionary state that cannot break through outward and can only continue to complicate internally. From an economic perspective, "involution" often occurs in situations where market mechanisms partially fail, manifested as a continuous increase in input of production factors that can drive up total output, but due to diminishing marginal returns, resource allocation efficiency continues to decline. For a period of time, "inward competition" has occurred in some industries in China. In 2024, the production of major links in China's photovoltaic industry chain continues to rise, but some links are operating at a loss. At one point, hundreds of companies flooded into the field of new energy vehicles, and the fierce price war put pressure on the overall profits of the industry, even some leading car companies were unable to achieve profitability. The "internal competition" among enterprises is to some extent related to the policies of local governments, such as the "GDP only" performance view and imperfect assessment and evaluation system, which have caused some places to excessively invest resources in homogeneous fields in pursuit of short-term economic growth goals, creating "policy depressions" but failing to improve overall development efficiency.
