The GDP in 2022 was 121,020.7 billion yuan according to preliminary figures released in January 2023, with a low real growth rate of 3.0%, which was far below the annual target of 5.5%.
Looking at the growth rate by quarter, the GDP growth rate was 4.8% in January–March, 0.4% in April–June, 3.9% in July–September, and 2.9% in October–December (as of the time of announcement in January 2023; the following growth rates by quarter are as of that same point in time).
However, these figures are versus the same quarter of the previous year, and this differs from the calculation method used in Europe, the U.S., Japan, and other industrialized nations. In the industrialized nations, the October–December 2022 growth rate is calculated compared to the previous quarter, July–September 2022. Because this shows growth versus the previous quarter, it is called the quarter-on-quarter growth rate which is the growth rate over a period of three months, and the values are extremely small. For that reason, this rate is usually announced after being multiplied by four and converted to an annualized growth rate.
In contrast, in China, the October–December 2022 growth rate is calculated compared to October–December 2021, that is, one year prior. Because this is the growth rate since the same period of the previous year, it is called the year-on-year growth rate. The year-on-year growth rate is greatly affected by the conditions of the economy during the prior year.
For example, the year-on-year growth rate in January–March 2021 was extremely high at 18.7%, but this is because COVID-19 was spreading in January–March 2020 and the economy was greatly depressed, so the base for the comparison was extremely low.
Conversely, the year-on-year growth rate in October–December 2021 was a low 4.3%. This is not because the economy in the October–December 2021 quarter worsened compared to the January–March 2021 quarter. Rather, it is because the economy in the October–December 2020 quarter had greatly recovered, and so the base for the comparison was high.
In this way, because the year-on-year growth rate is greatly affected by the economic conditions of the previous year, it is difficult to accurately judge whether the economy is presently favorable, or trending downward, or flat based on the figure. For that reason, the industrialized nations use the quarter-on-quarter growth rate, which is a comparison versus the previous quarter.
Because of strong requests from the industrialized nations for calculation of quarter-on-quarter figures as well, the National Bureau of Statistics of China announces quarter-on-quarter figures as estimated values when it announces its year-on-year growth rate figures each quarter. According to those figures, the 2022 quarter-on-quarter growth rates were 1.3% in January–March, minus 2.4% in April–June, 3.9% in July–September, and 0.0% in October–December. When these are multiplied by four, they become annualized figures, but based on this calculation, the April–June annualized growth rate would be around minus 9.6%, which greatly diverges from the 0.4% figure announced by the National Bureau of Statistics. However, these are only estimated values, and they are revised retroactively every three months. For example, the 2022 quarter-on-quarter growth rates announced in October 2022 were 1.6% in January–March, minus 2.7% in April–June, and 3.9% in July–September. It is common for the figures to be revised upward or downward by around 0.1 percentage points, and when these are multiplied by four the error in the annualized rate becomes still larger.
In 2022, there was a resurgence of COVID-19 in Shanghai and elsewhere from March, and because Shanghai was locked down from the end of March through the end of May, the economy was greatly depressed during the April–June quarter. In the July–September quarter, the spread of infection eased, and the resumption of business and production steadily advanced, so the economy rapidly recovered.
However, there was another resurgence of COVID-19 from October. Because regional governments responded with a policy for the complete containment of COVID-19 (the so-called zero-COVID policy), in response, protests broke out among the citizens in November, and from November the Central Committee of the Communist Party of China (CPC) suddenly eased the zero-COVID policy to calm citizens’ discontent. Consequently, the number of COVID-19 patients rapidly increased, and the economy and society fell into disorder. As a result, the economy slumped once again in the October–December quarter. Because of these developments, the 2022 quarter-to-quarter growth rates moved sharply up and down.
