The Impact

Digital economy is an important starting point for China’s high-quality economic development, which may have an impact on the level of industrial structure. This paper calculates the development level of digital economy by entropy weight method, selects the relevant data of 31 provinces and cities in China from 2012 to 2019, and uses the method of empirical test to analyze the impact of the development of digital economy on the upgrading of China’s industrial structure. The result shows that the development of digital economy can promote the upgrading of China’s overall industrial structure, which is significant at the level of 1%. Further research shows that the development of digital economy has regional heterogeneity on the upgrading of industrial structure in the eastern, central and western regions of China. The research of this paper has important practical significance for the high-quality development of China’s economy.

In order to firstly assure the mating features of high importance during the selective assembly process, a selective assembly method considering the feature weightings is proposed. All of the features are evaluated by fuzzy entropy weight method. Their weight coefficients which present the importance are defined. Based on the dissymmetrical quality loss function and the weight coefficients, the multi-objective model for selective assembly is established. A specific generic algorithm considering target weightings is used to solve the optimization model. It can search the preference region using the Pareto dominant order to derive satisfactory solutions with high quality. Finally, the method is used for the selective assembly of a certain aero engine’s subassembly to invalidate the feasibility.

Coordination Degree

Investment in transportation infrastructure is bound to promote the economic development . Coordinated development of transport and economy is the best state. This paper discusses the principle of coordinated development between traffic and economy, build evaluation index system of transport and economy development, use entropy weight method to calculate the composite score, draw traffic - economy coordination degree model. Then set Huanggang City of Hubei province example to illustrate the usefulness of the model.

<p>In order to promote high-quality economic development, China has implemented large-scale tax cut and fee reduction. In order to verify the role of tax cut and fee reduction in promoting high-quality economic development, the author uses entropy weight method and relative deviation fuzzy evaluation method to establish a multi-dimensional index system to measure the level of China's economic development. Finally, the author also puts forward countermeasures and suggestions from the perspective of tax cut and fee reduction policy optimization, which include publicizing the preferential policies of tax cut and fee reduction through multiple channels, strengthening the efforts of tax cut and fee reduction of private enterprises and comprehensively implementing the legal principles of tax and so on to provide theoretical reference for the high-quality development of China's economy. </p>

In recent years, various large- and medium-sized shopping malls have been essential components of each city with the speed-up of China’s urbanization process and the improvement of residents’ living standard. A method for evaluating fire risk in shopping malls based on quantified safety checklist and structure entropy weight method was proposed according to related literatures as well as laws and regulations by analyzing the characteristics of fires occurring in shopping malls in recent years. At first, the factors influencing the fire risk in shopping malls were determined by carrying out on-site survey and visiting related organizations to construct an evaluation index system for fires occurring in shopping malls; afterwards, a quantified safety checklist composed of four parts (i.e. safety grade, grade description, scoring criterion and index quantification) was established based on related laws and regulations; subsequently, index weights were determined by utilizing structure entropy weight method, thus putting forward a method for assessing fire risk in shopping malls based on quantified safety checklist and structure entropy weight method. Eventually, the applicability of the evaluation method was validated exampled by Wal-Mart. The research result provides a theoretical basis for further improvement of the theoretical system for fire risk evaluation in shopping malls, and also exerts practical and guidance significance on timeous and effective early warning as well as prevention and control of building fires.
