complete comparability during the comprehensive evaluation of new
kinetic energy index of economic development.
The commonly used methods of the same measurement are: relativization
processing, standardization processing and efficacy coefficient method,
etc. Because standardization processing and efficacy coefficient mainly
focus on the lateral correlation evaluation, but this study mainly reflects the
vertical development trend, the relativization treatment method is selected
to calculate the index value.

Single index (positive index) ki = Single index value in reporting period I1/
Single index value in base period I0

Single index (inverse index) ki = Single index value in base period I0/ Single
index value in reporting period I1
(II) Weight definition
The common methods to define weight are Delphi method, Analytic
Hierarchy Process, Coefficient of Variation, Multiple Correlation Coefficient
method, Entropy method, among which Delphi method and AHP method
will be affected by subjective factors, and Coefficient of Variation method,
Multiple Correlation Coefficient method and Entropy method need a large
number of samples to determine the accurate data model. In view of the
limited data and the equal importance of all aspects of kinetic energy
conversion, this study adopts the method of equal-weighted assignment.
(III) Composite index measurement
Commonly used methods of index measurement are: composite index
method, comprehensive score of target value and principal component
analysis method, etc. Because the target value is difficult to define for
kinetic energy conversion, and the sample size required by the principal
component analysis method is large, this study mainly reflects the old and
new kinetic energy conversion through the development and change of the
composite index. The principle of "index of mean" is adopted in the
determination of composite index. The calculation procedure and process
are as follows: the value of single index is calculated first, and then the
weighted average of single indexes (or sub-index) is calculated. The formula
is:

Where k is composite index, I0 is index value in base period, I1 is index number
in reporting period, and W is weight.
