Abstract
Purpose
This study aims to elucidate the causal relationship between corporate greenwashing and celebrity leaders.
Design/methodology/approach
This study considers winning the National Model Worker Award as an external shock for producing celebrity leaders and conducts a difference-in-difference (DID) estimation with listed companies from 2009 to 2022 in the Chinese context.
Findings
The findings indicate an increase in greenwashing of companies with celebrity leaders in the post-award period. Stakeholder pressure can moderate the effect of celebrity leaders on corporate greenwashing.
Originality/value
This study enriches the research on the antecedents of greenwashing and the impacts of celebrity leaders. The findings advance the understanding of the real effect of celebrity leaders on environmental, social and governance (ESG) efforts and provide new insights into how celebrities respond to legitimacy pressures.

Abstract
Purpose
The selective laser melting (SLM) technique, as a typical additive manufacturing process, is widely used for the fabrication of metallic biomedical components. In terms of biodegradability, zinc and its alloys represent an emerging generation of metallic materials for biomedical implants. The purpose of this paper is to obtain the Zn and Zn10Mg alloys with high mechanical properties using the SLM technology. The relationship between the processing parameters and the porosity of pure Zn and Zn10Mg alloy samples was investigated.
Design/methodology/approach
The samples were fabricated using SLM technology working in an inert gas closed chamber. Preliminary experiments were conducted to analyze the laser power and gas flow on evaporation, single track form and porosity. To evaluate the influence of factors on relative density, the response surface methodology was applied.
Findings
The satisfactory results of the proposed method were achieved, in which the relative density of the components reached up to 99.63%, and compression strength reached 214 ± 13 MPa under optimal processing conditions.
Originality/value
Zinc is categorized by its low melting and boiling point, which leads to the high porosity of the components. It is difficult to prepare the Zn alloy samples with high relative density using SLM technology. This work successfully achieved dense Zn and Zn10Mg samples and investigated their microstructure, mechanical properties and corrosion behavior.

Abstract
Purpose
In this research, the highly dense bulk Cu-5Sn alloy specimens were fabricated using selective laser melting (SLM). This study aims to establish the relationship between laser power (LP), scanning speed (SS) and hatch space (HS) with surface roughness (Ra) and density. To obtain Cu-5Sn alloy formed parts with high strength and low surface roughness. The microstructure and mechanical properties of SLMed Cu-5Sn were investigated.
Design/methodology/approach
The relative density (RD) was optimized using the response surface method (RSM) and analysis of variance. First, the Ra of SLMed formed specimens was studied to optimize the forming process parameters with a good surface. Then, the dense specimens were studied by ANOVA and the RSM to obtain dense specimens for mechanical property analysis.
Findings
Dense specimens were obtained by RSM and ANOVA. The tensile properties were compared with the casted specimens. The yield and ultimate strengths increased from 71 and 131 MPa for the cast specimens to 334 and 489 MPa for the SLMed specimens, respectively. The ductility increased significantly from 11% to 23%, due to the refined microstructure of the SLMed specimens, as well as the formation of many twin crystals.
Originality/value
The Ra, RD and mechanical properties of SLM specimens Cu-5Sn were systematically studied, and the influencing factors were analyzed together. This study provides a theoretical and practical example to improve the surface quality and RD.

Abstract
China has achieved continuous economic growth and become more integrated with the global economy since the start of the current financial crisis in late 2008. As the second largest economy in the world, China's political policies, economic and social development have influence on global economy. Attention has been paid worldwide to the current Chinese legal system, political policies and the development of economic reform since China entered the World Trade Organisation in November 2001. The corporate governance reform is the centre of the enterprise reform. In September 1999, The Fourth Plenum of the Chinese Communist Party's 15th central Committee identified that corporate governance is the core of the modern enterprise system. In recent years China has made significant progress in developing the foundations of a modern corporate system. There are more than 1,200 companies which have successfully diversified their ownership through public listing and 80% of small and medium size companies have been transformed into non-state-owned enterprises. More and more state-owned enterprises are on the way to transforming into corporations. China has formed a legal framework for corporate governance.

Abstract
Purpose
This paper aims to investigate whether the accounting reform in China has improved the relevance of China's accounting information. It seeks to investigate the association between earnings and book value of equity to share returns before and after the introduction of the Accounting System for Business Enterprises (ASBE) in 2001 for A‐ and A&B‐share firms.
Design/methodology/approach
The paper employs the return regression model. The pre‐ASBE period is designated as 1997 through to 2000, and the post‐ASBE period is designated as 2002 through to 2004. All firms listed on the Chinese stock market during the investigation period constitute the sample.
Findings
It is found that accounting information better explains share returns for both A‐share firms and A&B‐share firms in the post‐ASBE period. The paper also finds that the book value of equity for A&B‐share firms is incrementally value relevant to that of A‐share firms in the post‐ASBE period.
Research limitations/implications
Further studies will contribute to understanding how governance mechanisms and liquidity influence the association between accounting information and share returns in the Chinese A‐share market.
Practical implications
The findings provide empirical evidence regarding the relevance of accounting information in emerging markets.
Originality/value
The paper contributes to the extant value relevance literature by investigating time periods surrounding the issue of ASBE in 2001 in the Chinese stock market.
