A Comparative Analysis of the Business Models of Uber and Didi under Sharing Economy Background

With the development of ‘Internet +’, a new business model the Sharing Economy is booming，which as a revolutionary power to overthrow the business modes of traditional industries. The development of sharing economy has unique advantages and urgent reality in China. Therefore, based on the current situation of sharing economy, this paper analyzes and contrasts the business models of Uber and the Didi by using Johnson and Christensen's ‘Four Elements’business model，concludes business model of sharing economy should have certain characteristics, such as advocated sharing concept, setting up the Internet platform, providing personalized service, establishing the trust mechanism, the supply and demand matching reshaped.Finally, this paper provides comprehensive suggestions for the better development of Chinese enterprises under the sharing economy: enterprises should know their own advantages, not blindly copying the world's leading enterprises, and make effort to build a new model with Chinese characteristics to sharing economy; create "Internet platform + cooperation partner + customers†model and seek cross-border collaboration; In-depth understanding and analysis the macro and micro-environment of international market, seeking cooperation with foreign domestic enterprise, to speed up enterprises to "go out"

On the Application of the Event Portfolio Strategy in the MICE Development of Dalian

Based on the discussion of Canadian scholars' Getz "Portfolio Optimization" strategy, combined with the problems and challenges of China's convention and exhibition city, this paper takes the exhibition city Dalian as an example, through the interviews with relevant experts in the exhibition industry, As a comprehensive development strategy, which can effectively integrate the number, size and type of exhibition activities in the Chinese environment, and optimize the allocation of resources in the exhibition activities, balance the interests of stakeholders and Promote the sustainable development of the three aspects of the development of the exhibition city has important guiding significance

Temporal and Spatial Variations in the Normalized Difference Vegetation Index in Shanxi Section of the Yellow River Basin and Coal Mines and Their Response to Climatic Factors

Investigating the spatiotemporal variations in the Normalized Difference Vegetation Index (NDVI) in the Shanxi section of the Yellow River Basin and its coal mining areas holds significant importance for dynamic vegetation monitoring and mining area management. This study employs MODIS NDVI data and combines various analytical methods, including trend analysis and coefficient of variation analysis, to reveal the characteristics of NDVI spatiotemporal variations and their response to climatic factors in the study area. The results indicate the following: (1) The overall NDVI in the Shanxi section of the Yellow River Basin exhibits a growth trend with an annual growth rate of 1.82% and a 36% increase. Among the mining areas, the NDVI increase is most prominent in the Hebaopian mining area with a 100% growth, while the QinYuan mining area shows the lowest increase at 21%; (2) The NDVI in the Shanxi section of the Yellow River Basin displays high fluctuations, with areas of moderate and high fluctuations accounting for 54.39% of the total. The Hebaopian mining area has a substantial portion of high-fluctuation areas at 38.85%; (3) According to the Hurst index analysis, future vegetation changes in the Shanxi section of the Yellow River Basin are uncertain, with approximately 9.77% of areas expected to continue improving; (4) The variations in the NDVI and climatic factors across the Shanxi section of the Yellow River Basin display spatial heterogeneity. The NDVI exhibits a positive correlation with both temperature and precipitation, with the correlation with precipitation being more pronounced than that with temperature. Precipitation exerts a more significant influence on the NDVI than temperature. These findings not only provide scientific guidance for vegetation restoration and area management in the Shanxi section of the Yellow River Basin and its mining areas but also serve as a scientific basis for decision making regarding vegetation management under the influence of climate change and human activities

Syntheses, Photoluminescence, and Electroluminescence of a Series of Sublimable Bipolar Cationic Cuprous Complexes with Thermally Activated Delayed Fluorescence

Three thermally activated delayed fluorescence cationic cuprous complexes [Cu­(POP) (ECAF)]­PF₆ (<b>1</b>, POP = bis­(2-diphenylphosphinophenyl)­ether, ECAF = 9,9-bis­(9-ethylcarbazol-3-yl)-4,5-diazafluorene), [Cu­(POP) (EHCAF)]­PF₆ (<b>2</b>, EHCAF = 9,9-bis­(9-ethylhexylcarbazol-3-yl)-4,5-diazafluorene), and [Cu­(POP) (PCAF)]­PF₆ (<b>3</b>, PCAF = 9,9-bis­(9-phenylcarbazaol-3-yl)-4,5-diazafluorene) with bipolar 4,5-diazafluorene ligand substituted by bis-carbazole have been successfully prepared, and their UV absorption, photoluminescent properties, and electrochemical behaviors were investigated. At room temperature, complexes <b>1</b>, <b>2</b>, and <b>3</b> exhibit efficient yellowish-green emission with peak maxima of 550, 549, and 556 nm, respectively, and lifetimes of 5.7 μs. In powder states, the quantum yields (ϕ_PL) of 22.4% for <b>1</b>, 18.5% for <b>2</b>, and 20.0% for <b>3</b>, respectively, are found. These metal phosphors can be vacuum-evaporated and applied in the organic light-emitting diodes (OLEDs) of indium tin oxide/poly­(3,4-ethylenedioxy-thiophene):poly­(styrenesulfonate) (40 nm)/4,4′,4″-tri­(9-carbazoyl)­triphenylamine (15 nm)/cuprous complexes (10 wt %): 1,3-bis­(9-carbazolyl)­benzene (30 nm)/1,3,5-tri­[(3-pyridyl)-phen-3-yl]­benzene (50 nm)/LiF (0.5 nm)/Al (100 nm). Complex <b>1</b>-based device D1 achieved a maximum luminance of 11 010 cd m^–2, a current efficiency of 47.03 cd A^–1, and an external quantum efficiency of 14.81%. The high electroluminescence efficiencies of these complexes are assumed to be due to their good thermal stabilities and capture of both singlet and triplet excitons. The research presented here provides a powerful tool toward highly efficient and cheap OLED devices
