'Overcapacity' should be viewed from a global, dynamic perspective

The Joe Biden administration recently announced new tariffs on a variety of imports from China, particularly on electric vehicles and lithium batteries. Prior to that, US Treasury Secretary Janet Yellen mentioned the issue of so-called overcapacity in China during her recent trip to the country. The issue of alleged overcapacity in China's green industry has once again become a widely discussed topic.

Industrial overcapacity is not a new topic. Many scholars have discussed its causes. They generally believe that it's a result of reckless investment by businesses amid incomplete market information, undue government interventions in microeconomic activities, a sudden fall-off in market demand caused by domestic or overseas factors, and economic cycles. But these views are based on a static analysis, which only factors in the causes of industrial overcapacity at a given point in time, instead of analyzing industrial overcapacity from a dynamic perspective that includes changes to the industrial structure.

Economic growth requires continuous upgrading of the industrial structure. Each industry has its own life cycle. Its share of the overall national economy will rise at the beginning, and then it begins to decline after reaching its peak. During the decline period, the share of emerging industries will rise. The industrial structure is upgraded amid the trade-off between one industry and another, driving sustained economic growth.

Our research team has recently collected carbon intensity data (carbon emissions per unit of export volume) and China's export data from 2002 to 2021 to examine the relationship between the carbon intensity of Chinese products and China's export structure.

We have reached three conclusions. First, the share of China's product exports in China's total exports and destination markets shows an inverted U-shaped curve of first increasing and then decreasing. Second, the products with higher carbon intensity reach their export peaks earlier than those with lower carbon intensity. Third, this non-linear relationship is mainly caused by changes in the comparative advantages of industries due to an increase in the cost of carbon emissions in China.

Thus, changes to the industrial structure based on carbon intensity are in line with the general law of industrial change. Industries with different levels of carbon intensity have their own life cycles. Products with higher carbon intensity will be gradually phased out, while greener products with lower carbon intensity will gradually account for a larger and larger share of the national economy. As a result, the overall carbon intensity and carbon emissions of the national economy will decline.
