Abstract: In this study, we executed an empirical research on how executive commitment will affect the corporate performance through the mediation of organizational acceptance and member participation in response to external environment stimulus. The subjects of this study are the members of corporates with experience of consulting in Korea and data collection was conducted by questionnaire survey. The questionnaire consist of 25 items which including 7 general items and we used the Likert 5 point scale for the measurement. Statistical analysis was performed by using SPSS and AMOS programs. Basic statistical analysis, factor analysis, reliability analysis and measurement model analysis were conducted. Regression analysis was conducted to test the mediated effects by using structure equation model analysis. The hypothesis that executive commitment affects on consulting result was neglected because the standardized coefficient (minus value) didn't get a positive effect. But the p-value was less than the significance level and so, its effect is significant. Therefore, it was affirmed that an effect of the hypothesis was lowered by the influence of the parameters. The effect of executive commitment on organizational acceptance and member participation showed that the standardized coefficient was significant and so, the more executive commitment increase, organizational acceptance and member participation will also increase. The impact of acceptance of organization and participation of member on consulting result also showed similar results. In addition, by looking at analysis results of the indirect effect and total effect between executive commitment and consulting result, the mediated effect was statistically significant. In other words, organizational acceptance and member participation have a significant mediated effect on the impact of executive commitment on consulting result. After this, much more research is necessary on the specific tools and methodologies that can fuse and strengthen the executive commitment, organizational acceptance and member participation in the implementation of corporate consulting.
