An online questionnaire was set out in survey form on Google Docs in or-der to collect data. The survey was conducted of participants in Mongolia. 236 usable responses were obtained from Mongolian potential customers in order to examine constructs. The findings suggest that co-design and individual tendency of trust have significant positive effect on the trust levels throughout intention to purchase.展开更多
