Starting from the theoretical mechanism of the impact of financial agglomeration on regional green innovation efficiency, and using panel data from 30 provinces in China from 2009 to 2017, this study calculates a financial agglomeration index and green innovation efficiency applying principal...

The length of stay for tourists is shrinking for traditional tourism destinations, with tourists instead opting for short breaks to multiple destinations. The reasons for these changes include the increasing number of low cost airlines reduces the cost per journey, alongside heightened...

Using the volatility spillover index method based on the quantile vector autoregression (QVAR) model, this paper systematically examines structural changes and corresponding spillover effects within 20 major stock markets under both extreme and normal market conditions, using data spanning from...

Infrastructure construction is one of the basic driving forces of social and economic development. Since 1978, the construction of infrastructure in the People's Republic of China (PRC) has experienced rapid development, which has given a strong impetus to the PRC's modernization. But behind the...

Autonomous driving (AV) technology has elicited discussion on social dilemmas where trade-offs between individual preferences, social norms, and collective interests may impact road safety and efficiency. In this study, we aim to identify whether social dilemmas exist in AVs' sequential decision...

Mean-field games (MFGs) are developed to model the decision-making processes of a large number of interacting agents in multi-agent systems. This paper studies mean-field games on graphs (𝒢-MFGs). The equilibria of 𝒢-MFGs, namely, mean-field equilibria (MFE), are challenging to solve for...

Research and development (R & D) competition is standard, and it heavily affects patent values. This study captures R&D competition's effects on patent values using game-theory approaches. Cost-reduction patent values increase with technology level and decrease with the competition. Technology...

New product development (NPD) has become a key factor for improving enterprise competitiveness. Integrated product development (IPD) is considered a best practice for addressing the complexities of NPD, but most enterprise NPD processes face problems, such as low efficiency, long turnover, and...

Purpose - The authors derive the necessary mathematics, provide computer simulations, provide links to free and user-friendly computer programs, and analyze real data sets. Design/methodology/approach - Cohen’s d, which indexes the difference in means in standard deviation units, is the most...

Environmental pollution, climate warming and other issues have become global issues, and the use of renewable energy as the best way to solve the problem has gradually attracted the attention of all countries. Uncertainty has an important effect on the production of renewable energy. Through a...
