Abstract
Purpose
The purpose of this paper is to provide a framework to illustrate how network governance based on banks’ e-commerce platform reduces loan risks and mitigates credit rationing in supply chain financing (SCF).
Design/methodology/approach
The authors conceptualize network governance in terms of authority structure and interorganizational mechanism dimensions, and derive the model of its determinants through arguments drawn from the existing literature. Structural equation modeling is employed to test the theoretical model on data collected from a sample of 271 independent supply chain trading partners in rural China.
Findings
The findings indicate that network governance based on banks’ e-commerce platform could integrate the operations and finances in supply chain management to solve the problems of information asymmetry, costly monitoring, insufficient qualified collaterals and mitigate farmers’ credit rationing. The collaborative credit-granting mechanism and collaborative debt enforcement mechanism formed by the authority structure and interorganizational mechanisms are the key factors to realize the complete compatibility of incentives. The bank e-commerce platform can provide a foundation for the authority structure and interorganizational mechanisms to enhance the predictability of applicants’ transaction and then safeguard the financial exchanges in supply chain.
Practical implications
The research results indicate that it is important to support farmers to establish long-term transaction relationships with leading enterprises through organizational innovation in the development of agricultural industrialization and build a visualization platform for SCF through technological innovation.
Originality/value
This paper contributes to the limited knowledge about network governance mechanisms in SCF by illustrating the model of network governance based on banks’ e-commerce platform and its determinants.

The purpose of this paper is to analyze manufacturers' production decisions and governments' low-carbon policies in the context of influencer spillover effects.
Abstract
Purpose
The purpose of this paper is to analyze manufacturers' production decisions and governments' low-carbon policies in the context of influencer spillover effects.
Design/methodology/approach
This paper investigates the impact of the social influencer spillover effect on manufacturers' production decisions when they collaborate with intermediary platforms to sell products through marketplace or reseller modes. Game theory and static numerical comparison are used to analyze our models.
Findings
Firstly, under low-carbon policies, the spillover effect does not always benefit manufacturer profits and changes non-monotonically with an increasing spillover effect. Secondly, in cases where there are both a carbon emission constraint and a spillover effect present, if either the manufacturer or intermediary platform holds a strong position, then marketplace mode benefits manufacturer profits. Thirdly, regardless of business mode used when environmental damage coefficient is high for products; government should implement cap-and-trade regulation to optimize social welfare while reducing manufacturers’ carbon emissions.
Practical implications
This study offers theoretical and practical research support to assist manufacturers in optimizing production decisions for compliance with carbon emission limits, enhancing profits through the development of effective influencer marketing strategies, and providing strategies to mitigate carbon emissions and enhance social welfare while sustaining manufacturing activities.
Originality/value
This paper addresses the limitations of prior research by examining how the social influencer spillover effect influences manufacturers' business mode choices under government low-carbon policies and analyzing the social welfare of different carbon emission restrictions when such spillovers occur. Our findings provide valuable insights for manufacturers in selecting optimal marketing strategies and business modes and decision-makers in implementing effective regulations.

Abstract
Purpose
The purpose of this paper is to describe and explain the advertising behavior seen as an activation strategy performed by Olympic sponsors in an emerging market context. It provides insights into the strategic goals related to sponsorship.
Design/methodology/approach
The longitudinal approach taken opens the possibility to explore the dynamics of the strategies of Chinese as well as foreign firms in China. Theories on how sponsorship works cannot assist in explaining outcomes of sponsor-linked marketing, and since the actors involved rarely divulge their genuine intentions or their reciprocal contractual arrangements with the sponsored property, a new methodology has to be developed. A means-objective framework of sponsoring consists of six factors, which were applied to analyze 739 advertisements, articles and press releases collected from Chinese newspapers and Chinese official web pages covering a period of eight years (2001-2008) prior to the Olympic Games in Beijing. Based on a qualitative content analysis and nine means-objectives combinations in sponsorship patterns the authors discovered four dominant advertising strategies.
Findings
Lead-time is a key concept when analyzing sponsor advertising strategies. The authors conclude from the longitudinal data that the time gap between signing the contract and the dates of the event influences the strategy of the sponsoring corporations. The authors also observe that the advertising content changes over time and the sponsors craft different “advertising strategies” in different periods. Within this context the authors categorized two different advertising strategies. The sponsors are assumed to conduct a “Short Advertising Strategy” different from the “Long Advertising Strategy.” Both are examples of activation strategies.
Originality/value
Advertising strategies and activation seems to be dependent on the lead-time to the Olympic Games and the level of internationalization of the sponsoring firm.

Abstract
Purpose
To address the lack of data in this field and determine the relationship between the coefficient of friction and the interference between locomotive wheels and axles, this study evaluates the theoretical relationship between the coefficient of friction and the interference under elastic deformation.
Design/methodology/approach
When using numerical analyses to study the mechanical state of the contacting components of the wheels and axle, the interference between the axle parts and the coefficient of friction between the axle parts are two important influencing factors. Currently, as the range of the coefficient of friction between the wheel and axle in interference remains unknown, it is generally considered that the coefficient of friction is only related to the materials of the friction pair; the relationship between the interference and the coefficient of friction is often neglected.
Findings
A total of 520 press-fitting experiments were conducted for 130 sets of wheels and axles of the HXD2 locomotive with 4 types of interferences, in order to obtain the relationship between the coefficient of friction between the locomotive wheel and axle and the amount of interference. These results are expected to serve as a reference for selecting the coefficient of friction when designing axle structures with the rolling stock, research on the press-fitting process and evaluations of the fatigue life.
Originality/value
The study provides a basis for the selection of friction coefficient and interference amount in the design of locomotive wheels and axles.

This paper aims to investigate the friction and wear properties of Cr-Ni-Mo-V steel against 440C stainless steel under both water and water–silica mixture lubricant.
Abstract
Purpose
This paper aims to investigate the friction and wear properties of Cr-Ni-Mo-V steel against 440C stainless steel under both water and water–silica mixture lubricant.
Design/methodology/approach
The Cr-Ni-Mo-V steel specimens were taken from a forged steel brake disc with the process of quenching at 900°C and tempering at 600°C. The tribological testing was performed using a contact configuration of ball-on-flat with a liquid cell according to the ASTM standard. Detailed examinations on the worn surface were analyzed using a scanning electron microscope.
Findings
The results indicate that the friction coefficient and friction damage of the steel sliding under water–silica mixture are higher than those under water. The friction coefficient decreases with increasing load and increases with the sliding speed for the two lubricants. The mass wear rate presents a rising trend with both sliding load and speed. The wear mechanisms of the Cr-Ni-Mo-V steel sliding under the two lubricants are oxidation wear, abrasive wear and fatigue wear.
Research limitations/implications
Because of the chosen tribological testing approach, the research results could not describe the tribological performance of the brake disc accurately during actual braking process of the high-speed train. Therefore, researchers are encouraged to test the proposed propositions further.
Originality/value
This study shows that the tribology behavior of the Cr-Ni-Mo-V steel with water or water–silica mixture lubrications helps the industrial firms and academicians to work on the wear of the brake disc in rainwater or wet environment.

Abstract
Purpose
Risk perception is an essential factor affecting how individuals evaluate risk, make decisions and behave. The impact of risk perception on customer purchase behavior has been widely studied; however, the association has been debated. Therefore, the purpose of this paper is to examine the relationship between risk perception and customer purchase behavior and to examine factors that could moderate it.
Design/methodology/approach
This study conducted a meta-analysis of this relationship and examined factors that could moderate it. Six databases were comprehensively searched. Two reviewers independently selected the studies for inclusion, extracted data and assessed quality. Pearson's r was used as the effect estimate. A total of 33 studies were included in the meta-analysis.
Findings
The results revealed a negative relationship between risk perception and customer purchase behavior. The geographical region, purchase channel and country development level affected the relationship. The correlation between perceived risk and purchase behavior in European consumers was the highest, followed by the correlation in American consumers; the weakest correlation was found in Asian consumers. For consumers in developed countries, perceived risk had a stronger negative influence on customer purchase behavior than that for consumers in developing countries. The perceived risk of online purchase channels had a stronger negative impact on customer purchase behavior than that of offline purchase channels.
Research limitations/implications
Risk perception is a useful context in which to explain barriers to customer purchase behavior. In addition, reducing consumers’ risk perception and perfecting the market transaction process with respect to buying behavior should be further studied.
Originality/value
The findings of this review indicate a direct negative relationship between risk perception and customer purchase behavior. To the best of the authors’ knowledge, this review is the first to meta-analytically summarize the impact of risk perception on customer purchase behavior in social sciences research, and it also illuminates new perspectives for future studies.

Abstract
Purpose
This paper sets out to study the corrosion of No. 20 carbon steel without film and with films of different qualities in high‐temperature boiler water with different Cl− concentrations.
Design/methodology/approach
The static simulated experiment in high‐pressure autoclave and the surface analysis methods of EPMA and XRD were carried out to study the corrosion effect.
Findings
Under the following conditions: T=360±3°C, pH = 9.40±0.10, cO2<0.020 mg/l, the density of pitting corrosion on specimens without a protective film increased with the increase of CCl− content, while CCl− was > 0.2 mg/l. The film on specimens with integral films would not dissolve observably even until the CCl− concentration was as high as 0.8 mg/l. Films with corrosion pits would begin dissolving when the Cl− concentration reached 0.4 mg/l. The main constituents of the oxidative films in the gas and liquid phases both were Fe3O4.
Practical implications
In order to prevent carbon steel from corroding in boiler water containing Cl− under conditions of low‐phosphate and low‐sodium hydroxide treatment, the concentration of Cl− should be strictly controlled.
Originality/value
It was found that the presence of excessive Cl− in boiler water accelerated the corrosion of No. 20 carbon steel and the maximum permissible concentration of Cl− under the conditions (temperature and pressure) of sub‐critical drum boilers was 0.2 mg/l. The research results can provide theoretical guidelines for preventing the facilities of power plants from corroding.
