Novel Model of Product Sales in Financial and Trade Activities Participation based on the Variation Coefficient Method

Abstract

The trade of cultural products is a new industry arising from the big background of economic globalization, and it is of strong permeability, wide cross-industry, and relatively intensive knowledge. It stands at the top of the commodity industry chain, is gradually recognized and cherished by people. Its development is also one of the obvious signs to measure the regional competitiveness. In view of the corresponding evaluation index of the sales route of cultural products in financial and trade activities participation, the study carries out the comprehensive weighting, and optimizes the results of the weighting based on the variation coefficient method. The importance between the subjective weight and objective weight is verified according to the instance data and the operating income margin of cultural products is predicted. The results show that this method takes full account of the relative variation range of the original data, and realizes the dynamic weighting value of the index, which greatly reduces the influence of the subjective factors. The network microstructure analysis results based on the node influence and node instability under time windows display that the partition characteristic of the index network weakens in the financial crisis period, and the network’s community structure evolves smoothly in the financial stable period. These results provide cases and references for further empirical researches on the correlations of financial markets, also are helpful for speeding up the opening process of the domestic capital market and the prevention of international financial market risks.
