This study also found a positiove relationship between market orientation and trust and commitment. As previously noted,Bigne and Blesa (2003) found that the market orientation of a supplier positively influenced distributors’ commitment and that distributors’market orientation had a significant and positive effect on suppliers’trust and commitment. When partners’trust increases,their commitment in the relationship also increases.
