Abstract
Purpose
The purpose of this paper is to develop non-leaching and eco-friendly antimicrobial waterborne polyacrylates with excellent antibacterial properties by grafting antibacterial vinyl monomer, glycidyl methacrylate (GMA) modified polyhexamethylene guanidine hydrochloride (PHMG).
Design/methodology/approach
PHMG of different molecular weights were modified by GMA to synthesize antibacterial vinyl monomer, GMA-modified PHMG (GPHMG). Different content and molecular weights of GPHMG were used to synthesize antimicrobial waterborne polyacrylates through emulsion polymerization.
Findings
The addition of GPHMG gained by modifying PHMG showed little influence on thermal stability of the films, but decreased the glass transition temperature(Tg). Meanwhile, the tensile strength decreased, while the breaking elongation increased. The antibacterial properties of the antibacterial films with different GPHMG contents were studied, when GPHMG content was around 0.9 Wt.%, antibacterial films showed excellent antibacterial activity (antibacterial rate >= 99.99 per cent). When weight content of GPHMG in the films remained constant, antibacterial property of films increased first and then decreased with the increase of molecular weight of GPHMG. The structural antibacterial polymer film had more perdurable antibacterial activity than the blended one.
Research limitations/implications
The grafting efficiency of GPHMG to antimicrobial waterborne polyacrylates could be further improved.
Practical implications
Antimicrobial waterborne polyacrylates with excellent antibacterial properties can be used to antibacterial coating and adhesive.
Originality/value
The antibacterial properties of films with different molecular weight of GPHMG were studied, and the durability and stability of antibacterial properties between structural antimicrobial films and blended antimicrobial films were also investigated by ring-diffusion method.

Abstract
Purpose
The purpose of this paper is to study enterprise innovation in the perspective of external supplier relationship. On this purpose, this paper examines the impact of supplier change on enterprise innovation with the moderating role of market competition.
Design/methodology/approach
Using 2012–2020 empirical data of Chinese listed manufacturing enterprises, this paper investigates the relationship among supplier change, market competition and enterprise innovation through a two-way interaction model.
Findings
The results show that supplier change has a negative impact on enterprise innovation. And market competition intensifies the negative relationship between supplier change and enterprise innovation. Additional analyses indicate that the main effect and the moderating effect are more significant when the enterprise is non-state-owned or has lower ownership concentration.
Originality/value
This paper studies enterprise innovation from the perspective of external stakeholders. It focuses on supplier relationship in a dynamic variation view, instead of the traditional static ones. Moreover, this paper explores the contingency effect of market competition and gives practical implications for managers to adjust innovation strategy flexibly.

Abstract
Purpose
Influencer marketing is a newer interactive marketing model that has attracted the attention of scholars and marketers. The study aimed to examine the mediation role of influencer credibility (IC) and the moderation role of self-esteem in the effects of individuals' parasocial relationships (PSR) with YouTube influencers on their product attitudes (PATs) and purchase intentions (PIs).
Design/methodology/approach
The researchers used an online survey to test a sequential mediation model and moderation mediation models using Hayes PROCESS modeling.
Findings
The researchers revealed a sequential mediation model that IC and PAT mediate the association between PSR and PI. Individuals who perceived IC to be low were more likely to buy an endorsed product when their self-esteem got lower. When their self-esteem is low, individuals tend to purchase the endorsed products if they have stronger PSR with the influencers. However, they are less likely to buy the endorsed products when their self-esteem gets higher.
Originality/value
The study expands the dimensions of IC. The persuasive power of IC and influencer-user relationship was affected by individual differences, namely, self-esteem. Brands should pay attention to customers' personalities, motivations and preferences when designing strategies to market their products via social media.

Abstract
Purpose
This article will select 25 years of subdivided data to perform Kaplan–Meier survival analysis on the export trade relations of Chinese wooden flooring, use discrete-time cloglog models to analyze influencing factors, use logit and probit models to test the robustness, and try to systematically reveal the duration of China's wood flooring export trade and its influencing factors.
Design/methodology/approach
This study used Kaplan–Meier survival function estimation method. In the survival analysis, survival function and hazard rate function are often used to characterize the distribution of survival time.
Findings
The continuous average export time of China's wooden flooring is relatively long, about 14 years. China's wooden flooring has a negative time dependency. After the export trade exceeds the threshold value of 15 years, the failure rate of trade greatly decreases, which has a “threshold effect.” Gravity model variables have a significant impact on the duration of China's wooden floor export.
Originality/value
Studying the duration of forest products trade is of great significance for clearing deep-level trade relations and promoting sustainable development of forest products trade.

Abstract
Purpose
The purpose of this paper is to investigate the mechanism through which stressors influence job crafting. Based on regulatory focus theory, this study explores the mediating role of work regulatory focus between the challenge-hindrance stressors and approach-avoidance job crafting and the moderating role of trait regulatory focus.
Design/methodology/approach
The authors collected survey data in a northwestern city of China from 578 employees working in the finance, real estate and IT industries. Results were analyzed using Mplus 7.
Findings
The results reveal that challenge stressors have a positive effect on both approach job crafting (i.e. increasing structural job resources, increasing social job resources and increasing challenging job demands) and avoidance job crafting (i.e. decreasing hindering job demands) via work promotion focus. On the other hand, hindrance stressors have a positive effect on only avoidance job crafting via work prevention focus. In addition, trait promotion focus accentuates the influence of challenge-hindrance stressors on work regulatory focus, as well as the indirect effect of challenge-hindrance stressors on approach-avoidance job crafting respectively. Trait prevention focus only weakens the influence of challenge stressors on work promotion focus.
Research limitations/implications
This study unfolds how stressors relate to job crafting. However, the cross-sectional design may limit the causal inferences.
Originality/value
This study provides new insight into the relationship between stressors and job crafting by explicating the motivational mechanism and boundary conditions.

Abstract
Purpose
This study aims at developing a better understanding of the relationship between network embeddedness and incremental innovation capability and further examines the moderating effect of open innovation.
Design/methodology/approach
This paper adopts hierarchical regressions to validate the theoretical model and collect the patent data of the top 54 firm patentees in the smartphone industry as empirical sample. Using patent citation network data, this paper estimates the relationship between open innovation, network embeddedness and incremental innovation capability.
Findings
This paper empirically shows that structural embeddedness exerts a negative effect on incremental innovation capability, while relational embeddedness is positively related to incremental innovation capability. And open innovation strengthens the relationship between network embeddedness and incremental innovation capability.
Originality/value
This paper shifts the focus of the determinants of incremental innovation capability from internal factors to the external network features by exploring the linkage between network embeddedness and incremental innovation capability. A counterintuitive conclusion is that structural embeddedness shows a negative effect on firm's incremental innovation capability. Furthermore, in contrast to most previous studies, which only focus on the direct effect of open innovation on the firm's incremental innovation capability, our study examines the moderating effect of open innovation on the relationships between network embeddedness and incremental innovation capability. At last, the results provide practical guidance for firms to occupy the beneficial network positions and adopt appropriate open innovation strategies to improve their incremental innovation capability.

Abstract
Purpose
This study aims to examine whether compensation committees dominated by co-opted directors are less effective in mitigating the CEO horizon problem.
Design/methodology/approach
The author uses a sample of 7,280 firm-year observations from 1998 to 2011.
Findings
In this study, the author finds evidence of opportunistic research and development (R&D) reduction and accruals management in firms with retiring CEOs and compensation committees dominated by co-opted directors. Moreover, it is found that R&D reduction and income-increasing accruals are less discouraged when determining the compensation for retiring CEOs by compensation committees that are dominated by co-opted directors. The results suggest that compensation committees dominated by co-opted directors are less effective in adjusting CEO compensation to mitigate the CEO horizon problem.
Originality/value
The study reveals that co-opted directors are weak monitors. Moreover, the study adds empirical evidence to the debate of organizations’ CEO horizon problem. Finally, the study adds to the literature on corporate governance, revealing that compensation committees play an important role in mitigating an organization’s CEO horizon problem by adjusting CEO compensation.
