The Sequential Pricing of Ride-Hailing System with Rental Service in the Context of Fleet Electrification

Journal of Systems Science and Systems Engineering 2024年第1期33卷 77-105页

作者： Yaoyao Ku Peng Wu Qiang Ren Yiqing Wang business school Sichuan UniversityChengdu610065China

Surging demand and reduced capacity in the ride-hailing industry have prompted numerous ride-hailing platforms to build their own car-rental services catering to drivers who do not possess private vehicles. However, the trade-off between the ride-hailing service and the car-rental service is an important issue that is still unclear in theory. Moreover, ride-hailing platforms are transitioning towards all-electric fleets in the context of Carbon Neutrality goals and government regulations. This paper considers a ride-hailing system comprising a monopolist ride-hailing platform, an electric vehicle (EV) rental firm, and a gasoline vehicle (GV) rental firm. Furthermore, we build a stylized model to study the sequential pricing of the system. The equilibrium outcomes show the significant impact of the ride-hailing platform’s decision to continue or withdraw offering EV rental services on EV and GV drivers’ net earnings, rental prices, and wages. The ride-hailing platform providing EV rental services increases EV drivers’ net earnings but decreases the GV driver wages and rental prices. However, the EV rental service offered by the ride-hailing platform does not necessarily lead to an increased total profit for the system. The improved profitability of the system by the ride-hailing platform providing EV rental services is contingent upon lower rider prices and higher fuel costs. The ride-hailing platform’s EV rental services provision also effectively fosters the ride-hailing fleet’s electrification. Furthermore, as the number of riders increases, the ride-hailing platform should reduce the commission rate for EV drivers to maintain competitiveness and profitability.

While progress has been made in information source localization,it has overlooked the prevalent friend and adversarial relationships in social networks.This paper addresses this gap by focusing on source localization in signed network models.Leveraging the topological characteristics of signed networks and transforming the propagation probability into effective distance,we propose an optimization method for observer selection.Additionally,by using the reverse propagation algorithm we present a method for information source localization in signed networks.Extensive experimental results demonstrate that a higher proportion of positive edges within signed networks contributes to more favorable source localization,and the higher the ratio of propagation rates between positive and negative edges,the more accurate the source localization becomes.Interestingly,this aligns with our observation that,in reality,the number of friends tends to be greater than the number of adversaries,and the likelihood of information propagation among friends is often higher than among adversaries.In addition,the source located at the periphery of the network is not easy to identify.Furthermore,our proposed observer selection method based on effective distance achieves higher operational efficiency and exhibits higher accuracy in information source localization,compared with three strategies for observer selection based on the classical full-order neighbor coverage.

How can technology and efficiency alleviate the dilemma of economic growth and carbon emissions in China's industrial economy? A metafrontier decoupling decomposition analysis

引用

Petroleum Science 2024年第2期21卷 1415-1428页

作者： Miao Wang Chao Feng School of Business Zhengzhou UniversityZhengzhou450001HenanChina school of Economics and business Administration Chongqing UniversityChongqing400030China

This paper attempts to explore the decoupling relationship and its drivers between industrial economic increase and energy-related CO_(2) emissions(ICE). Firstly, the decoupling relationship was evaluated by Tapio index. Then, based on the DEA meta-frontier theory framework which taking into account the regional and industrial heterogeneity and index decomposition method, the driving factors of decoupling process were explored mainly from the view of technology and efficiency. The results show that during2000-2019, weak decoupling was the primary state. Investment scale expansion was the largest reason hindering decoupling process of industrial increase from ICE. Both energy saving and production technology achieved significant progress, which facilitated the decoupling process. Simultaneously, the energy technology gap and production technology gap among regions have been narrowed, and played a role in promoting decoupling process. On the contrary, both scale economy efficiency and pure technical efficiency have inhibiting effects on decoupling process. The former indicates that the scale economy of China's industry was not conducive to improve energy efficiency and production efficiency, while the latter indicates that resource misallocation problem may exist in both energy market and product market.

CEOs’Diverse Career Experiences and the Effectiveness of Compensation Contracts:Evidence from Compensation Stickiness

引用

Journal of Systems Science and Systems Engineering 2024年第1期33卷 52-76页

作者： Shimin Sun Yongheng Wang Yawen Wang Mengyu Mao School of Business Administration Northeastern UniversityShenyang110169China

CEO compensation stickiness represents an important indicator to measure the effectiveness of compensation contracts.This study uses CEO career experience data and compensation stickiness data from Shanghai and Shenzhen A-share listed companies from 2015 to 2020 to investigate the compensation contracts’effectiveness of CEOs with diverse career experiences.The findings are as follows:1)Compensation stickiness is more pronounced for CEOs with diverse career experiences.According to the mechanism test,these CEOs with diverse career experiences can obtain compensation incentives by reducing corporate uncertainty perception and improving total factor productivity.This approach leads to increased compensation stickiness and the effectiveness of compensation contracts.CEOs with diverse career experiences may receive excess compensation by raising agency costs,which intensifies compensation stickiness and weakens the effectiveness of compensation contracts.2)Compensation stickiness of CEOs with diverse career experiences is more significant in companies with lower investor protection,which brings about less effective compensation contracts.In contrast,in companies with higher diversification,the compensation stickiness of CEOs with diverse career experiences is more significant,which delivers more effective compensation contracts.The conclusions deepen the research of CEO compensation contracts and provide a helpful reference for CEO compensation management practices.

Solving complex post-disaster reconstruction challenges requires the altruistic involvement of heterogeneous stakeholder groups.However,small,more organized groups,such as government parastatals,private developers,and contractors often exploit large,unorganized groups,such as affected communities,leaving them more vulnerable to future disasters.Based on data collected from a case study in Pakistan,this study proposed a framework to assess,anticipate,and mitigate the exploitation of vulnerable stakeholders in post-disaster reconstruction projects.The framework draws on influential management theories and utilizes reciprocal relationships between stakeholder attributes(power,legitimacy,and urgency),participation,and exploitation.The study also argued for non-binary treatment of stakeholder attributes.The framework will allow practitioners to address issues around the exploitation of stakeholder interests in future post-disaster reconstruction projects.

Essential Players in Cooperative Games with Graph Communication Structure

引用

Journal of the Operations Research Society of China 2024年第1期12卷 93-108页

作者： Guang Zhang Jing-Yi Ge business school University of Shanghai for Science and TechnologyShanghai200093China

A class of cooperative games with graph communication structure is studied in this paper by considering some important players,namely essential players.Under the assumption that only connected coalitions containing essential players are able to cooperate and obtain their worths,the class of graph games with essential players is proposed as well as an allocation rule.The proposed value follows the spirit of the Myerson value defined by applying the Shapley value on a modified game.Three properties,feasible component efficiency,the inessential component property,and fairness,are provided to fully characterize this value,where feasible component efficiency and fairness follows the same ideas of component efficiency and fairness for classical graph games,and the inessential component property says that the total payoffs of the players in a non-feasible component is zero.Moreover,some computational aspects of the proposed value and comparisons with disjunctive permission value for games with permission structure are also studied,respectively.

The Capital Market Reaction and the Influencing Mechanism of the Establishment of the Data Basic Institutional System

引用

Social Sciences in China 2024年第1期45卷 134-156页

作者： Liu Bai Zhang Ailian School of Business and Management Jilin University

This study uses a sample of A-share listed companies to investigate the impact of China's Data Basic Institutional System on capital market reactions and the mechanism by which it exerts influence.The findings reveal that within a 5-day period before and after the policy announcement,listed companies with high data resources experience a significantly higher abnormal return compared to those with low data resources.Moreover,this difference becomes more pronounced as enterprise technology intensity increases.Furthermore,the policy enhances the capital market's perception of the value of data resources and its potential for generating multiplier effects.Additional tests confirm that post-implementation of the policy,the capital market reevaluates the long-term value of enterprises associated with data resources.This comprehensive examination contributes empirical evidence to support academic research,inform policy formulation,and guide strategic planning in relevantindustries.

Crowding-in or Crowding-out:How Infrastructure Investment Affects Household Consumption

引用

China Finance and Economic Review 2024年第1期13卷 43-66页

作者： Zhiyu Yan Yufei Yuan Yi Xue school of International business and Economics University of International Business and Economics

This paper constructs a dynamic model of household consumption decisions and accordingly designs empirical analyses to identify how infrastructure investment affects private consumption.The estimation results of provincial panel data reveal that infrastructure investment can not only indirectly promote household consumption through the income channel but also directly promote household consumption expansion through the expectations channel,with a significant"crowding-in"effect.However,the effect is significantly weaker in provinces with a lower housing supply elasticity,showing the"crowding-out"pattern through the wealth channel.Household survey data provide an explanation for individual heterogeneity.Infrastructure investment has a greater pushing effect on house prices in provinces with a lower housing supply elasticity.Rapid house price growth has significant"crowding-out"effects on the consumption of wealthy households.This not only significantly weakens the driving effect of infrastructure investment on aggregate household consumption,but also increases wealth inequality in the long term.This paper explains how infrastructure investment affects household consumption and the corresponding role played by house prices,providing empirical evidences for theoretical studies related to macro-regulatory policies in China.

China & World Economy 2024年第3期32卷 215-242页

作者： Yi Che Meng Yuan Yan Zhang Lin Zhao School of Business East China University of Science and TechnologyChina School of Business Xiangtan UniversityChina school of Economics Shanghai University of Finance and EconomicsChina

China's exports experienced a rapid recovery after the outbreak of the 2019 COVID-19 pandemic.A primary engine was cross-border e-commerce(CBEC)trade,which bucked the downward export trend during the pandemic.By exploring the variation in the number of CBEC comprehensive pilot zones across provinces,we identified the causal impact of CBEC on exports using monthly province-product-destination data for 2019 and 2020.We found strong and robust evidence that CBEC contributed to exports during the pandemic by promoting the expansion of incumbent exports(intensive margin)rather than through the expansion of product categories and exporting partners(extensive margin).Specifically,higher pandemic risk suppressed the role of CBEC at the intensive margin while enhancing it at the extensive margin.Exports to developed countries benefited more from CBEC,both intensively and extensively.Compared with final products,a larger number of intermediate products were exported through CBEC after the outbreak of the pandemic.

Registration system reform and initial public offering ownership preference:Evidence from China

引用

China Journal of Accounting Research 2024年第1期17卷 74-95页

作者： Xihao Wu Di Zhang Zhongxin Wu International business school Hainan UniversityChina

Whether registration system reform(RSR)can curb administrative intervention and create a fair market environment has long been a concern in China.We explore this issue from the perspective of the initial public offering(IPO)preference based on the entropy balancing method,and findings are as follows.First,an IPO ownership preference exists under approval system.That is,state-owned enterprises(SOEs)are more likely than private enterprises to obtain IPO approval.However,RSR significantly changes this preference,especially for non-politically connected private enterprises.Second,the post-IPO market performance of SOEs is inferior to that of private enterprises under approval system,thus excluding the view that approval is prioritized for SOEs because of superior performance.Third,compared with SOEs,private enterprises are more likely to switch the issuance system from approval system to registration system;this change makes it easier for them to obtain IPO approval,indicating that private enterprise owners perceive the registration channel to be fairer.Fourth,the effect of RSR on IPO ownership preference mainly occurs in companies in three major urban agglomerations in China—the Pearl River Delta,the Yangtze River Delta,and the Beijing–Tian jin–Hebei region—and in technology-intensive industries.Collectively,our findings reveal that RSR cultivates a fairer IPO approval process.
