Empirical Analysis of the Matching Degree between Energy Equipment Manufacturing and Market Demand: A Global Perspective

Characteristics analysis of five evaluation methods.

Method	Advantages	Disadvantages
Osculating value method	Simple principle, clear concept, an easy to implement process, and objective evaluation results	When performing multi-index evaluation, different dimension indexes should be quantified.
RSR method	Solving the problem of multiple indicators, comprehensive evaluation, and the influence of dimensions not considered	Some information of the original data will be lost when the index is converted to rank.
TOPSIS method	A selection technique based on the similarity of ideal goals, which is a very effective method in multiobjective decision analysis	The weight of each indicator needs to be determined artificially and has a certain degree of subjectivity.
Entropy value method	Determining the index weights according to the degree of variation of the index values and avoiding the deviation caused by human factors	It ignores the importance of the index itself, and the dimension of the evaluation index cannot be reduced.
Efficacy coefficient method	Calculating and scoring the evaluation object from different aspects according to the complexity of the evaluation object	The two evaluation criteria, satisfactory value and unallowable value, are difficult to decide and operate.
