The growth rate of GDP reflects the change in the physical scale of the final social outcome over a certain period of time. Since the scale of GDP is measured by the amount of value, the changes in the scale of the value volume in different periods include both quantitative changes and factors. In order to make the GDP of the reporting period ** compatible with the GDP of the base period**, when calculating the GDP growth rate, the GDP of the current period should first be excluded from the current GDP and other factors, and the GDP development rate calculated at comparable prices should be obtained, and finally the GDP growth rate should be obtained by subtracting 100.

The growth rate is positive, indicating the degree of growth; A negative growth rate indicates the degree of decline, also known as the degree of negative growth. The formula is as follows: GDP growth rate = GDP at comparable prices in the reporting period GDP at comparable prices in the base period * 100%-100% In addition, the growth rate is a relative indicator of the degree of growth of social and economic phenomena, indicating that the level of the reporting period has increased by several percent or several times compared with the level of the base period.

The annual GDP was 209407 billion yuan, an increase of one percentage point over the previous year on a comparable basis. Among them, the added value of the primary industry was 2.47 trillion yuan, an increase; the added value of the secondary industry was 102004 billion yuan, an increase; The added value of the tertiary industry was 8,270.3 billion yuan, an increase.

Advantages of seasonal adjustments. Compared with the original data, the data after removing the influence of seasonal factors has the following five advantages: First, it more accurately reflects the basic trend of the data itself.

The use of scientific methods to measure, separate, offset and adjust seasonal factors from the actual time series data can make the series more accurately reflect the basic development trend of the indicator. Second, the data are comparable. Since seasonally adjusted data eliminates the influence of seasonal factors, data can be directly compared between different quarters or months.

Third, it can reflect the short-term changes in the economy in a timely manner, especially the turning point of the economic changes, which is very valuable for economic analysis and is also the biggest advantage of seasonal adjustment. Fourth, the seasonally adjusted data can be converted annually. Fifth, seasonally adjusted data can be used for short-term**.

Lack of seasonal adjustments. Seasonally adjusted data also has its own aspects that are difficult to understand: first, the adjusted time series are analyzed rather than directly observed.

The unadjusted time series are independent of each other, and the seasonality of the series is changed after adjustment, making them interrelated and less variable. Second, the same data, after different seasonalizations (because each new data comes out and is reseasonally adjusted as part of a new time series), is difficult to understand and accept. See.
