Understanding the potential of taxi sharing: The case of Chengdu.

The emergence of taxi sharing enhances urban transport efficiency and reduces carbon emissions. Using GPS tracking data from taxis in Chengdu, China, this study first outlines conditions for identifying shareable taxi orders based on their origins and destinations. We then develop a three-phase computational model to optimize matches among all potential shareable orders, calculating the shareable mileage and the proportion of original mileage that could be shared. Our comprehensive temporal and spatial analysis reveal a significant market for taxi sharing in Chengdu, with higher potential on workdays than non-workdays and four distinct demand peaks throughout the day. The morning peak on workdays and the night peak on non-workdays are particularly pronounced. Most shareable orders originate within major city districts. We find a positive correlation between the potential of taxi sharing and average traffic speed, and negative correlations with order volume, regional economic development, and population density. Functional zones related to Enterprises, Motorcycle Services, and Transportation Services exhibit significantly higher sharing potential. Compared to traditional taxi operations, taxi sharing significantly reduces total travel mileage. This quantitative analysis offers insights into the potential demand for taxi sharing among urban residents and may help government authorities optimize taxi resources for the sustainable development of urban transport.

Environmental innovation ambidexterity and customer relationship performance: evidence from the manufacturing industry in China.

Cleaner production and pollution prevention are not only essential for enterprises to improve resource utilization efficiency and competitiveness, but also realistic requirements for enterprises to comply with green manufacturing policies and regulations. Many previous studies have investigated the impacts of environmental innovation on products and environmental performance, but few of them have explored the impact of environmental innovation on customer relationships. The main purpose of this study is to investigate the basic strategies to enhance customer relationship in the context of green development. Building upon the resource-based view, the dynamic capability perspective, and the upper echelons theory, this study develops a conceptual model focusing on the effects of environmental innovation ambidexterity (EIA) on customer relationship performance (CRP), the mediating effects of green product innovation (GPI), and the moderating role of top management's environmental awareness. The results of a survey of 285 high-tech manufacturing enterprises in China show that EIA has a positive effect on CRP. The results of the study also indicate that GPI mediates the relationship between EIA and CRP, and top management's environmental awareness moderates the impact of EIA on CRP. The results offer novel insights for suppliers to improve CRP, and provide theoretical guidance for high-tech manufacturing enterprises to effectively implement pollution prevention and GPI.

Optimal Coordination Strategy for International Production Planning and Pollution Abating under Cap-and-Trade Regulations.

Because both pollution emissions and production policies often are international in scope, it is necessary to find optimal coordination strategies for international production planning and pollution abating. Differential game models are developed for multiple neighboring countries to reach optimal decisions on their production planning and pollution abating under cap-and-trade regulations. Non-cooperative and cooperative differential games are presented to depict the optimal tradeoffs between production planning and pollution abating. Hamilton-Jacobi-Bellman (HJB) equations are then employed to analyze the asymmetric and symmetric feedback solutions. Numerical simulations are used to illustrate the results. Five different dividends are also discussed. With the proposed strategies, more improvement will be directed toward production supplies and environmental issues than ever before.

An examination of the relationship between strategic group membership and hospital performance.

Membership in a particular strategic group, where a strategic group can be defined as groups of firms in an industry following similar competitive approaches and having similar market positions, defines the essentials of a firm's strategy. This study longitudinally examines the relationship between strategic group membership and performance in the hospital industry.
