In this paper, the diffusion process of China’s 3G users is researched based on the bass model. The parameters of the bass model are estimated with the recent number of 3G users. By the diffusion of the future 3G users simulated, the trends of 3G market in the next few years is predict, to look forward to help the behavior of operators and government decision-making .

Potential Impact of Mobile Phone Charger Standardization in China

引用

China Communications 2011年第7期8卷 136-143页

作者：张静梁雄健 School of Economics and Management Beijing University of Posts and Telecommunications

The standardization of mobile phone charger is proceeding steadily in Europe. This paper makes a quantitative analysis on the potential impact of this move in China. The demands for mobile handset and phone charger in China after the introduction of standardization are predicted based on bass diffusion model. The results indicate that the standardization would have little influence on mobile phone producers, but may charger makers face a fierce turbulence. Standardization would not only reduce the size of charger market, but also change the stable demand to a fluctuating pattern. Standardization of mobile phone charger can contribute to green economy greatly and provide the ICT industry a directive signal for green innovation in the future. Finally, suggestions for policy makers are provided based on the analysis.

The Application of Ecological Elements of Digital Technology in Construction Industry

引用

Open Journal of Civil Engineering 2021年第1期11卷 14-27页

作者： Jie Sun College of Civil Engineering and Architecture Zhejiang University Hangzhou China

The application of digital technology in the field of construction is still in its infancy, and the existing concrete framework of digital technology application in the construction industry and the study of applied ecological elements are not enough. The ecological elements of digital technology application in the construction industry are important factors that promote the healthy operation of the entire digital technology application ecosystem. Using grounded theory, we compiled the data of 33 researchers who participated in semi-structured interviews, and obtained 4 main categories and 9 sub-categories of ecological elements of digital technology application in the construction industry. Among them, the digital technology application mechanism is the core category of ecological application elements. We also used the Bass model to analyze the application trend of digital technology in the construction industry. In 2040, the number of construction companies applying digital technology will reach 98.66% of the maximum market potential.

作为产品体验的集中体现，口碑对新产品扩散的影响已越发明显。本文针对体验经济下新产品扩散问题，将口碑因素引入到经典bass模型，从口碑规模效应和比例效应两个角度，对经典bass模型进行了拓展，构建了双口碑效应下新产品扩散模型，并求得了模型解析解，通过性质分析对口碑与产品扩散的相关关系给出了理论证明。以电影为例，分别选取美国好莱坞2010至2014年间奥斯卡最佳提名影片42部和金酸梅奖最差提名影片23部合计65部电影样本进行实证分析，结果显示模型拟合绩效和预测绩效均有较好表现。
