Purpose This study explores impacts of innovation-adoption characteristics, food choice motives, segmentation and socio-demographics on consumer adoption of online-to-offline food delivery services (O2O-FDS) in a Western developed country – New Zealand – and an Asian developing country – China. Design/methodology/approach An online survey of 1,185 consumers provides data that the authors analyse using factor analyses, structural equation modelling and cluster analysis. Findings The following innovation-adoption characteristics and food choice motives have statistically significant effects on consumers' attitudes and/or purchase intentions towards O2O-FDS in the pooled sample and/or the samples of two countries: perceived incentive, perceived complexity, processed convenience, cheapness, taste appeal, safety-assured and purchase convenience. Three consumer segments are recognized: conservatives (26.6%), food-value seekers (40.8%) and pioneers (32.6%). Significant differences are found in marital status, age, household income, education level, household size, occupation, country and residential areas across the three segments. Originality/value This is the first study to systematically understand significant influencing factors for the O2O-FDS adoption by using a sample set composed of both Eastern and Western consumers.
