Abstract

The goal of this chapter is to respond to the theoretical inquiries by scholars who are interested in how the public–private partnership (PPP) models adapt to China’s context where political power dictates economic strategies. We also want to provide suggestions to policy designers who aim to promote a sustainable investment environment for domestic and international investors. We review the literature that explains the upside and downside of PPP projects in contemporary China. (1) We classify the trajectory of PPP evolution into four phases, i.e., emergence, growth, recession and revival. (2) We note that private companies take a disadvantageous position in the partnership compared with governments and state-owned enterprises because of a lack of specialized legislation, unequal competition between private companies and state-owned enterprises and the opposition from the civic society. (3) We identify political risks as the most influential risks. Political risks also lead to the misallocation of other risks between public and private parties that contributes to the high failure rate of China’s PPP projects. Based on these findings, we recommend governments to draft specialized legislation, stabilize the political environment and provide favourable subsidies to local governments to limit the risks involved in PPP projects. We also advise private enterprises and state-owned enterprises to focus on negotiating over task and risk division with governments when they make decisions to participate in PPP projects. This full review of studies on PPP development in China provides reliable recommendations to scholars, governments and enterprises.

Abstract

Purpose

This study aims to provide an estimation of carbon dioxide (CO2) emission abatement costs in China’s industry sector during the period of 2006-2010, and additionally provide an ex-post estimation of CO2 abatement cost savings that would be realized if carbon emission permits trading among different industry sectors of 30 provinces in China during the same period were allowed, to answer the question that whether the industrial carbon emission abatement cost can (partially) be recovered from carbon emission trading in China.

Design/methodology/approach

The joint production framework associated with the environmental technology is utilized for formulating the models for estimating abatement costs and simulating emission permits trading scheme. Several data envelopment analysis-based models that could deal with both the desirable and undesirable outputs within the above framework are utilized for abatement cost saving estimation. The weak disposability assumption and variable returns to scale assumption are applied in the modelling.

Findings

In China’s industry sector, during 2006-2010, the estimated CO2 emission abatement cost was 1,842 billion yuan, which accounts for 2.45 per cent of China’s total industrial output value; the emission abatement cost saving from emission permits trading would be 315 billion yuan, which accounts for 17.12 per cent of the emission opportunity abatement cost; and additional 1,065.95 million tonnes of CO2 emission reductions would be realized from emission permits trading, and this accounts for 4.75 per cent of the total industrial CO2 emissions.

Research limitations/implications

The estimation is implemented at the regional level, i.e. the emission permits trading subjects are the whole industry sectors in different Chinese provinces, because of the data limitation in this study. Further estimation could be implemented at the enterprise level to provide a deeper insight into the abatement cost recovery from emission permits trading.

Practical implications

The estimation models and calculation process introduced in this study could be applied for evaluating the efficiency and effectiveness of pollutant emission permits trading schemes from the perspective that whether these market-based abatement policy instruments help to realize the potential abatement cost savings.

Originality/value

To the best of the authors’ knowledge, no study has provided the estimation of CO2 emission abatement cost and the estimation of CO2 abatement cost saving effect from emission permits trading for China’s industry sector. This study provides the first attempt to fill this research gap.

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.

Abstract

This chapter studies the importance of implementation of innovational projects of technological growth through public–private partnership (PPP). The authors determine the probability of implementing a project of PPP depending on distribution of risks between its participants. Usage of the mechanism of PPP allows optimizing possible risks during implementation of innovational activities, attracting large business for creation and implementation of new technologies, and forming sustainable ties between R&D departments and business structures. The types of risks in the projects of PPP are given, as well as tendencies of their emergence depending on the stage of implementation of the innovational project, including the following: formation of policy on development of PPP; preparatory, implementary, commercialization of the results of joint activities; and monitoring and control over execution of the project. The algorithm of the system of risk management in innovational projects of technological growth on the platform of PPP is presented. The methods of overcoming the risks that appear during implementation of an innovational project of technological growth within PPP are given. A special attention should be paid to the fourth (distribution of risks) and fifth (reduction of risks) stages. During implementation of innovational projects with application of a business model of PPP, the risks are dealt with by the participant who can manage them better. Reduction of risks is achieved better if several strategies are used – for decreasing the influence of the risk on the innovational project (strategies of risk evasion, acceptance of the risk situation, compensation, transfer, and reduction).

Abstract

Purpose

This paper aims to propose a measurement principle and a calibration method of measurement system integrated with serial robot and 3D camera to identify its parameters conveniently and achieve high measurement accuracy.

Design/methodology/approach

A stiffness and kinematic measurement principle of the integrated system is proposed, which considers the influence of robot weight and load weight on measurement accuracy. Then an error model is derived based on the principle that the coordinate of sphere center is invariant, which can simultaneously identify the parameters of joint stiffness, kinematic and hand-eye relationship. Further, considering the errors of the parameters to be calibrated and the measurement error of 3D camera, a method to generate calibration observation data is proposed to validate both calibration accuracy and parameter identification accuracy of calibration method.

Findings

Comparative simulations and experiments of conventional kinematic calibration method and the stiffness and kinematic calibration method proposed in this paper are conducted. The results of the simulations show that the proposed method is more accurate, and the identified values of angle parameters in modified Denavit and Hartenberg model are closer to their real values. Compared with the conventional calibration method in experiments, the proposed method decreases the maximum and mean errors by 19.9% and 13.4%, respectively.

Originality/value

A new measurement principle and a novel calibration method are proposed. The proposed method can simultaneously identify joint stiffness, kinematic and hand-eye parameters and obtain not only higher measurement accuracy but also higher parameter identification accuracy, which is suitable for on-site calibration.

This work aims to demonstrate the vibration suppression of the rotor system with localized defects on bearing using an integral squeeze film damper (ISFD).

Abstract

Purpose

This work aims to demonstrate the vibration suppression of the rotor system with localized defects on bearing using an integral squeeze film damper (ISFD).

Design/methodology/approach

Experiments were carried out to study the vibration characteristics of the rotor system with ISFD mounted on fault deep groove ball bearings. Three fault bearings including bearing with outer race defect, inner race defect and ball defect have been used in this paper. The results were compared by use of vibration acceleration level, continuous wavelet transform and envelope spectrum.

Findings

It was found that ISFD shows excellent damping and vibration attenuation characteristics of the rotor system with defective bearing. The fault bearing rotor system with external ISFD considerably reduces the vibration energy and amplitude compared with the system without ISFD.

Originality/value

There is a dearth of experimental research pertaining to vibration characteristics of rotor system support by defective bearings with ISFD. Besides, the test provides evidence for the application of ISFD in vibration control of the rotor system with incipient defects on bearing.

Abstract

Purpose

Nylon 6 filaments have weak light and heat resistance in terms of stability, which restrict its application in engineering field. The purpose of this paper is to prepare a new photo-stabilization functional nanocomposite inks by using graphene nanosheet as UV light-resisting functional materials incorporated with polyurethane.

Design/methodology/approach

Sunlight-resisting functional nylon filaments were produced by the continuous solution dip coating technology, through which the functional inks was coated on the surface of nylon 6 filament. The surface morphology of the coated filaments was characterized by scanning electron microscopy and the graphene/polyurethane nanocomposite inks as the coating agent was confirmed and well dispersed on the fiber’s surface.

Findings

Under UV exposure, the strength loss rate of the graphene-modified nylon filaments was less than 50 percent, while that of the control nylon filament was over 85 percent, which indicated that graphene remarkably enhanced the light-resistant property of nylon. Besides, graphene/polyurethane-coated Nylon 6 filaments exhibited reasonable electrical properties and the electrical conductivity could reach 10–4 S/cm.

Originality/value

Graphene inks was first proposed as the UV photo-stabilization in this paper.
