Quantitative Analysis Theory of Industrial Competitiveness Theory

The theory of causes of industrial competitiveness belongs to the qualitative analysis part of the theory of industrial competitiveness. By introducing modern econometric analysis methods into theoretical research on industrial competitiveness, an econometric analysis theory of industrial competitiveness can be formed.

The general idea of ????the quantitative analysis of industrial competitiveness is: first, rationally select evaluation indicators, scientifically assign weights to each indicator, and construct a summation model; then, collect data according to each indicator, and then integrate it into the summation formula after standardization, that is,

Quantitative assessment level of competitiveness.

The quantitative analysis of industrial competitiveness must solve two key issues: one is the selection of evaluation indicators and the establishment of an indicator system; the other is scientifically assigning weights to each indicator.

Among them, in terms of indicator weighting, the weighting theory in statistics can be directly borrowed, and either traditional weighting methods or modern mathematical measurement methods such as principal component analysis can be used.

Some Chinese scholars divide industrial competitiveness evaluation indicators into two categories: one is display indicators, which mainly reflect market share and profit margin; the other is analytical indicators, which are further divided into direct cause indicators and indirect cause indicators.

Direct cause indicators mainly reflect productivity and corporate marketing management efficiency, etc., while indirect cause indicators are roughly equivalent to Porter's "four elements of national competitive advantage".

On the issue of indicator weighting, they use both traditional rules of thumb and principal component analysis in modern statistics.

5. The theory of development stages of industrial competitiveness.

From the perspective of industrial development, the theory of causes of industrial competitiveness and the theory of quantitative analysis of industrial competitiveness are both static industrial competitiveness theories, which intercept a certain cross-section of industrial development as the research object; the dynamic industrial competitiveness theory should take the industrial

Development as the research object, studying the competitiveness characteristics of each stage of industrial development.

The traditional theory for studying industrial development is the industrial life cycle theory.

The life cycle theory divides industrial development into four stages: formation, growth, maturity and decline.

Different stages of development have different characteristics.

Combined with the industrial life cycle theory, Porter summarized the "four-stage theory" of industrial competitiveness development, namely factor-driven stage, investment-driven stage, innovation-driven stage and wealth-driven stage.

The four stages are progressive in sequence, and retracement may also occur.
