Abstract

Purpose

This paper aims to compare and analyze the effect of the dual-credit policy and product substitution rate on the automakers’ operational strategies under different production modes (e.g. centralized and independent), and further illustrate which production mode is more conducive to improving new energy vehicle (NEV) development.

Design/methodology/approach

The decision-making models for a centralized production mode where an integrated automaker produces both NEVs and fuel vehicles (FVs) and for independent production mode where an NEV automaker faces competition from a traditional FV automaker were formulated. The equilibrium solutions of each production mode were obtained by extreme value and game theory methods. The conclusions of the theoretical analysis were further verified with numerical analyses using IBM-MATLAB R2019a. Some management insights could be obtained by comparison analysis.

Findings

Under the dual-credit policy, an increase in the NEV credit trading price will always raise production quantity of NEVs, but only in an independent production mode where a higher trading price will also bring higher total profits to NEV automakers. In addition, only when the NEV credit trading price is high enough, a rising product substitution rate will be more favorable to NEV production and restrain FV production. Furthermore, an independent production mode is more favorable for the initial production of NEVs, but as each of the two vehicle types captures a certain amount of market share, a centralized production mode will be more conducive to the full replacement of FVs by NEVs.

Originality/value

The main contributions of this study include the formulation of decision-making models for FVs and NEVs in not only a centralized production mode but also an independent production mode. Moreover, this paper comprehensively analyzes how the dual-credit policy and product substitution relationship affect automakers’ production and pricing decisions. Then, the specific conditions under which each production mode is more conducive to NEV production and sales are summarized. The results proposed in this study provide scientific managerial insights for automakers and policy makers.

Abstract

Purpose

High risk is one of the most prominent characteristics of the Chinese construction industry, and it poses a significant threat to construction projects. Owing to initiatives aimed at achieving high efficiency, low carbon emissions, etc., industrialization of the construction industry has become an inevitable trend in China. However, it remains to be discussed whether industrialization of construction can reduce the risks entailed in construction projects compared with traditional construction. The paper aims to discuss these issues.

Design/methodology/approach

Based on the theory of risk life cycle, this paper proposes a practical risk assessment technique to assess the risk life cycle, including the risk occurrence time and potential financial losses. This technique is then applied to assess the differences between the risks involved in an engineering, procurement and construction (EPC) project executed via traditional and industrial production modes.

Findings

The results show that the total duration of risks in the industrial construction project is half of that in the traditional project. In addition, the expected financial loss entailed in the industrial construction project is 29 percent lower than that in the traditional construction project. Therefore, industrial construction has the potential to optimize risk performance.

Originality/value

There is no significant difference between the traditional and industrial construction models in terms of probability of risk. The maximum total loss might occur in the procurement stage in the case of industrial production, and in the construction stage in the case of traditional production. Moreover, the total expected loss from risk in the EPC project in the industrial production mode is only half of that in the traditional production route. This study is expected to provide a new risk evaluation technique and promote an understanding of the life cycle of risk management in the construction industry.

Abstract

Purpose

The paper aims to outline the legal framework with regards to the civil liability of online intermediaries for users' misconduct in China, to analyze the problems in applying the rules related, and to introduce recent efforts from the State Council, the Supreme People's Court and legislature to combat online misconduct.

Design/methodology/approach

The paper intends to introduce these rules by studying the legislative history and several important case decisions. Comparisons with European and American approaches have also been made with regard to the self‐regulation issue.

Findings

Chinese courts have made many inconsistent decisions on the liabilities of online intermediaries in the past, but the legal framework is improving and the situation will become better given more clarifications from the Supreme People's Court. The State proactively promotes industry self‐regulation, together with public supervision in order to ensure the enforcement of rules.

Research limitations/implications

This paper gives a systematical analysis and thorough introduction to online intermediaries' liability since the first case in 1990s to the latest report, law amendment and provisions before July 2012 in China.

Originality/value

Cyberspace is an international community, thus, the worldwide harmonisation of cyber law shall be approached. An introduction of the Chinese legal framework and any latest updates from the State would be valuable for foreign policy makers and foreign online service providers to learn the Chinese situation and evaluate the Chinese internet market.

Abstract

Purpose

Due to existence of skin effect under rotational excitation, especially to high-frequency motors and power transformers run at the frequency of hundreds or even thousands of hertz, core losses will increase significantly, which may cause local overheating damage, and the efficiency and longevity will be decreased. The purpose of this paper is to accurately calculate the rotational anomalous loss in electrical steel sheets.

Design/methodology/approach

The influence of skin effect to rotational anomalous loss coefficient is described in detail. Based on the rotational core losses calculation approach, the transformed coefficient and parameters of rotational anomalous loss are determined in accordance with experimental data obtained by using 3D magnetic properties testing system. Then, a variable loss coefficient calculation model of rotational anomalous loss is built. Meanwhile, a separation of the total 2D elliptical rotation experimental core losses is worked out.

Findings

The two methods are analysed and compared qualitatively. It should be noted that the novel calculation model can be more effectively presented anomalous loss features. Moreover, quantitative comparisons between 2D elliptical rotation and alternating core losses have achieved beneficial conclusions.

Originality/value

Transformed rotational anomalous loss coefficient and parameters of electrical steel sheets considering skin effect are determined. Based on that, a novel calculation model evaluating 2D elliptical rotation anomalous loss is presented and verified based on the experimental measurement and the separation of the total 2D elliptical rotation core losses. The 2D elliptical rotation core losses separation method and quantitative comparison with alternating excitation are helpful to engineering application.

Abstract

Purpose

The purpose of this paper is to present evidence to the heated debate “whether Public-Private Partnership (PPP) model should be introduced into the hospitals” and, if so, how to promote the social sustainability of such PPP projects.

Design/methodology/approach

This paper has established an analytical framework to analyse the social sustainability of PPP projects. Using content analysis method, a single case study was carried out on the Northern Beaches Hospital in Sydney, Australia.

Findings

The results show that there are many problems related to social sustainability in the project, due to which employees and patients were exposed to most of them. Some recommendations are provided, including to strengthen the supervision of the project, provide sufficient information, establish communication channels and stakeholder participation, improve hospital policies and procedures, and strengthen government support.

Practical implications

This paper can provide guidance for the stakeholders in a partnership, including the public and private sectors, to analyse the social sustainability implications, and then plan and implement hospital PPP projects to achieve social sustainability goals. Meanwhile, it can also provide important reference for the employees, patients, local community and society to assess social sustainability issues, and provide relevant inputs to inform decision-makers in the development, delivery and management of hospital projects.

Originality/value

The research will contribute to knowledge of social sustainability of hospital PPP projects. The proposed analytical framework can be used to analyse and assess the social sustainability of such projects from the perspective of stakeholders.

Abstract

Purpose

As an innovation model for infrastructure and public service delivery, public–private partnership (PPP) has been widely adopted around the world. The knowledge spillover effect and policy diffusion mechanism have played an important role in promoting the development of PPP in the context of globalization. A comparative evaluation of the policy and management of PPP in different countries will help to understand the development of PPP, provide decision-making reference for PPP policy embedded with specific national conditions of each country, and also contribute to the global PPP knowledge body.

Design/methodology/approach

Based on the principle of comparability and representativeness, this study selected three countries, namely, China, India, and the United Kingdom for comparative analysis. This study first introduced the policy process and key institutions of PPP in three countries. Secondly, a comparative analysis of the development characteristics and application of PPP was conducted based on the official database of three countries. Finally, the differences, influencing factors and development trends of international PPP development were analyzed based on the comparative research results, and suggestions for PPP policy and management were put forward.

Findings

The research results indicate the development fluctuation and unbalanced spatial distribution of PPPs are a common phenomenon in the three countries. The UK has a significant impact on the policy and development of PPP in other countries. However, under the combined influence of factors such as economic, urbanization, political regime and social culture, there are significant differences in the PPP institution, application, and project characteristics in various countries. Due to international exchanges and knowledge spillovers, as well as the promotion of intermediaries, the development of PPP worldwide tends to converge.

Practical implications

Through conducting an international comparison of PPPs based on project data, this study provides a detailed and visualized overview of PPPs and a better understanding of PPP policy and management in different countries. The findings will be of interest to PPP investors, officers, practitioners, policymakers, researchers, and analysts. It enriches the portrait of global PPP market research, helps governments to improve the design of PPP institutions and policies, and provides references for decision-making of international investors when stepping into a new market.

Originality/value

This study is the first attempt to systematically compare and analyze the global PPP difference and development trend based on PPP project databases of different countries. Different from previous PPP comparative research based on perception data, the project data-based comparative analysis in this study is helpful to understand the characteristics, interrelations, and trends of global PPP development and enrich the existing PPP knowledge body. This study also proposes that it is possible to establish a global PPP knowledge community in the context of globalization and global production network.

This paper aims to investigate the influence of the contact status between the seal ring and its support on the seal performance in hydrostatic mechanical face seal.

Abstract

Purpose

This paper aims to investigate the influence of the contact status between the seal ring and its support on the seal performance in hydrostatic mechanical face seal.

Design/methodology/approach

A thermal fluid-solid interaction (TFSI) model of hydrostatic mechanical face seal is further developed, in which the multi-body contacts between components are particularly given more attention. The numerical models of the flow field and complete seal assemblies are developed. A specific energy equation is obtained to simplify the calculation of film temperature. Based on the mechanism for the continuity condition of the physical quantities at the fluid–solid interface, the TFSI model uses an on-line iterative coupling method.

Findings

The contact status between seal ring and its support affects the seal performance significantly. The rotating ring and the stationary ring contribute differently because of the contact status difference.

Originality/value

The contact status between the seal ring and the ring seat is key to gain an insight into the performance of the hydrostatic mechanical face seal thus provides guidance for mechanical seal design.

Abstract

Purpose

Based on the Chinese government's increased public‐private partnership (PPP) experience in the last decade, they have made a lot of efforts to improve the investment environment. This paper hence aims to conduct a more up‐to‐date evaluation of the potential risks in China's PPP projects.

Design/methodology/approach

As part of a comprehensive research looking at implementing PPP, a two‐round Delphi survey was conducted with experienced practitioners to identify the key risks that could be encountered in China's PPP projects. The probability of occurrence and severity of the consequence for the selected risks were derived from the surveys and used to calculate their relative risk significance index score.

Findings

The results showed that the top ten risks identified according to their risk significance index score are: government's intervention; poor political decision making; financial risk; government's reliability; market demand change; corruption; subjective evaluation; interest rate change; immature juristic system; and inflation. Further analysis was conducted on these risks so that the possible consequence, the most impacted parties, and the preferred allocation are discussed. Recommendations on commercial principles or contract terms between the Chinese government and private consortium are also provided.

Originality/value

These up‐to‐date findings concerning the probability and consequence of key risks would provide a valuable reference for private investors who are planning to invest in infrastructure projects in China.
