This paper examines the intention to use m-commerce in low-income consumers in Ecuador by expanding the original unified theory of acceptance and use of technology (UTAUT2) model to include the trust and perceived security constructs. A total of 344 Ecuadorians were surveyed according to the following criteria: 1) had made at least one purchase through their mobile device in the last month and, 2) belonged to the low and medium-low socioeconomic segment of the selected country. The results showed that facilitating conditions, hedonic motivation, habit, and perceived trust significantly and positively predict the intention to use m-commerce. The best predictor was facilitating conditions followed by perceived trust. Contrary to expectations, performance expectancy, social influence, and perceived security did not significantly affect low-income consumers' intention to use m-commerce. This study produced diverging results in significant constructs used to validate the UTAUT2, highlighting the need to examine this model in different countries further. The relationships of the core constructs of UTAUT2 vary according to the country studied, possibly due to differences in national culture and economic development that could moderate the impact of explanatory constructs of technology adoption.
本文通过扩展原始的技术接受与使用统一理论（UTAUT2）模型，纳入信任和感知安全结构，来研究厄瓜多尔低收入消费者使用移动商务的意愿。根据以下标准对344名厄瓜多尔人进行了调查：1）在过去一个月内至少通过移动设备进行过一次购物；2）属于所选国家的低和中低社会经济阶层。结果表明，便利条件、享乐动机、习惯和感知信任对使用移动商务的意愿有显著的正向预测作用。最佳预测因素是便利条件，其次是感知信任。与预期相反，绩效期望、社会影响和感知安全对低收入消费者使用移动商务的意愿没有显著影响。本研究在用于验证UTAUT2的重要结构方面产生了不同的结果，凸显了在不同国家进一步检验该模型的必要性。UTAUT2核心结构之间的关系因所研究的国家而异，这可能是由于国家文化和经济发展的差异，这些差异可能会调节技术采用解释性结构的影响。
