The New Kinetic Energy Index of China's Economic Development Increased by 35.4 Percent in 2021
In order to dynamically monitor the changes in the new kinetic energy of China's economic development, the Institute of Statistical Sciences of the National Bureau of Statistics calculated the new kinetic energy index of China's economic development in 2021 by using the fixed base index method based on the statistical monitoring system for new industries, new formats and new business models and the statistical index system of the new kinetic energy of economic development, and revised the historical index data. The results showed that the new kinetic energy index of China's economic development (taking 2014 as 100) was 598.8 , an increase of 35.4 percent over the previous year. In 2021, all sub-indexes increased compared with the previous year, among which the network economy index grew the fastest and contributed the most to the growth of the total index.
I. Network economy index
In 2021, the network economy index was 1963.6, an increase of 48.4 percent over the previous year, and the contribution rate to the overall index growth was 81.9 percent.
II. Economic vitality index
In 2021, the economic vitality index was 393.1, an increase of 18.8 percent over the previous year, and the contribution rate to the growth of the overall index was 8.0 percent.
III. Innovation driven index
In 2021, the innovation driven index was 293.5, an increase of 20.5 percent over the previous year, and the contribution rate to the growth of the overall index was 6.4 percent.
IV. Knowledge capability index
In 2021, the knowledge capability index was 182.7, an increase of 11.6 percent over the previous year, and the contribution rate to the overall index growth was 2.4 percent.
V. Transformation and upgrading index
In 2021, the transformation and upgrading index was 160.9, an increase of 7.0 percent over the previous year, and the contribution rate to the overall index growth was 1.3percent.

II. Calculation Method of New Kinetic Energy Index of Economic Development
The new kinetic energy index of economic development is a composite index constructed by using the basic data of "three new" surveys and the comprehensive evaluation method of linear weighting, which is used to reflect the development trend and process of new economic momentum. In order to better reflect the long-term change trend of new kinetic energy and dynamically monitor the accumulation process of new kinetic energy, the calculation method of new kinetic energy index of economic development is fixed base method, that is, taking 2014 as the base period, the index value represents the change trend of new kinetic energy of economic development in the reporting period compared with 2014. The specific steps are as follows:
1. Standardization of Basic Indicators
The standardized treatment of basic indicators is as follows:
Among them, 
is the corresponding index of 
, 
is the value of the reporting period and 
is the value of the base period. The base period selected for the index in this report is 2014, that is, it is calculated with 2014 as 100.
In addition, the index is converted into positive index by reciprocal method when the basic evaluation index is an inverse index, and then calculated by the above formula.
2. Calculation of Classification Index
The classification index formula of the new kinetic energy index of economic development is as follows:
Where, 
is the weight of
, 
is the 
index value of the classification, 
is the ordinal number of the first basic index in the whole index system in the category of
, and
is the ordinal number of the last basic index in the whole index system in the category of
.
3. Calculation of New Kinetic Energy Index of Economic Development
The calculation formula is as follows:
Among them, NEI is the new kinetic energy index of economic development and
is the weight of classification index of
.
4. Calculation of Contribution Rate of Sub Index to Total Index Growth
Contribution Rate=(Sub Index in Reporting Period-Sub Index in Last Year)×Sub Index Weight/( Total Index in Reporting Period-Total Index in Last Year)×100%
