From the perspective of time, the outbreak of large-scale power curtailment and suspension of production in China was in September this year, that is, in the third quarter. From the analysis of the basic economic data in the third quarter of China, it is concluded that although the economy seems to be rising, the overall economy has a clear downward trend and there are serious structural problems. In the third quarter, China's GDP was about 2.9 trillion yuan, and if inflation factors were not taken into account, it increased by 4.9% year-on-year and 0.2% month-on-month. Among them, the primary industry increased by 7.1% year-on-year, the secondary industry increased by 3.6% year-on-year, and the tertiary industry increased by 5.4% year-on-year. In fact, the basic economic data show that China's economy is stable and improving in the post-epidemic era, but why is it said that the current economy has a downward trend and where do structural problems come from? The added value of the tertiary industry accounted for 7.9%, 39.1% and 53.0% of GDP, respectively. Compared with the same period last year, the proportion of the secondary industry increased by 1.3 percentage points, and the proportion of the primary and tertiary industries decreased by 0.4 and 9.9 percentage points respectively. Obviously, China's basic economic growth rate in the third quarter of this year was driven by the secondary industry and industrial production, and the tertiary industry and services and consumption with the highest economic contribution efficiency did not perform as strongly as before the epidemic, mainly due to the backlog of overseas orders met with commodity price increases. If you go back to the previous data, you can find some structural problems. In 2020, the profits of industrial enterprises above designated size in China increased by 4.1% throughout the year, but the polarization was serious, such as the profits of professional equipment manufacturing and chemical raw materials and other industries increased by more than 20.9% year-on-year, but the profits of fuel processing industries such as petroleum and coal fell by more than 20% year-on-year, combined with the cyclical attributes of coal and the previously analyzed tertiary production structure problems, the rapid growth of the secondary industry has also increased China's unit GDP energy consumption while driving GDP. Under the coordination of the loss of raw materials (coal) in the previous year and the "double carbon" goal, coal mining has fallen into an unfavorable situation in both subjective and objective regulation. As a result, the demand for overseas orders rose while China's power and coal supply was stretched, and the data actually foreshadowed the occurrence of power curtailment in the third quarter.
