The purpose of this paper is to prepare the Mn‐Si‐Fe‐Cu‐Al alloy explosion suppression materials, and determine the corrosion behavior of aluminum alloy explosion suppression materials in HCl and NaOH solutions. The different mechanism of corrosion was discussed.

In this paper, Mn‐Si‐Fe‐Cu‐Al alloy explosion suppression materials were prepared, and the electrochemical behavior of the EAESM was studied. The corrosion parameters were calculated and the mechanism of the corrosion process was discussed. The corrosion behavior was characterized by immersion tests and SEM at room temperature.

Mn‐Si‐Fe‐Cu‐Al alloy explosion suppression materials have been prepared. SEM, the polarization curves showed that materials have corrosion resistance. The best content of Al alloy is Mn 0.880%, Si 0.135%, Fe 0.383% and Cu 0.0835%.

The results of this investigation show that adding alloying elements can form new strengthening phases that influence the corrosion resistance of alloys.

The purpose of this paper is to investigate how the pay gap between the management and ordinary employees influence corporate technology innovation.

This study built a tournament model based on inventor innovation and career promotion. In addition, the authors use IV-GMM estimation method to address the possible endogeneity issue in the regressions.

Based on the unbalanced panel data of patents and pay gap in 1,501 Chinese listed manufacturing firms during 2001-2015, this paper finds that the pay gap could lead inventor innovation and improve technology innovation. The pay gap could encourage corporate innovation significantly: 1 percent increase in pay gap may increase the number of patents by 2 percent in the next year. The pay gap between the management and ordinary employees facilitates corporate innovation via two possible channels. First, inventor innovation and career promotion. Inventors are selected into the management mainly based on their innovation output. The larger the pay gap, the more innovation incentives and patents would gain. Second, investment increase in technology innovation. The pay gap and more patents that inventors gain would increase the ratio of inventors promoted to the management, who tend to pour more resources into R&D activities and absorb more inventors to the management due to their sectionalism and R&D preference. The above two channels constitute a positive feedback mechanism among technology innovation, inventor promotion and increase in R&D investment.

This paper highlights that pay gap between the management and ordinary employees is an important issue that could encourage corporate innovation. The conclusions imply that pay gap could encourage inventors to work hard and produce more patents, which could help them to enter into the management such as executives or directors.

This study contributes to the current literature by implying that pay gap could have positive effects on innovation through theoretical and empirical analysis. Also, this study finds that inventor promotion due to the pay gap is a critical channel to stimulate corporate technology innovation.

As two essential styles of firm decision-making, the relationships among effectuation logic, causation logic and firm performance are unclear. It is helpful to deepen the understanding of reasoning theory and the process of decision-making. The purpose of this paper is to explore the relationship between effectuation logic, causation logic and firm performance.

Based on 31 independent empirical studies (including 11,600 samples) published by predecessors, meta-analysis is used to systematically integrate the impact of two decision-making styles on firm performance and explore the potential factors affecting their relationship.

The results show a positive correlation between two decision-making styles and firm performance and the influence of effectuation decision-making style in firm performance is slightly stronger. However, the application environment is different: in the emerging market, the causation decision-making style is more effective for firm performance management. When the firm chooses the effectuation decision-making style, it is more effective for performance management in the emerging market. In addition, the industry type, firm performance evaluation tools, national development level and firm scale and firm age can significantly moderate the impact of two decision-making styles on firm performance.

Both decision-making logics are possible ways for firm to success. Still, the future needs to dig deeper into the black box that can unlock the decision-making styles to achieve firm performance or competitive advantage based on other factors of the decision-behavior-outcome business model, more longitudinal data and experiments.

To the best of the authors’ knowledge, this is the first study to explore the impact of decision-making styles (effectuation logic and causation logic) on firm performance using a meta-analysis.
