This research analyzes and answers the question ＂Does customer experience management impact to customer loyalty shopping at supermarket, in the case of Mekong Delta, Vietnam？＂, 321 customers of supermarkets in the Mekong Delta were interviewed by questionnaire. The descriptive statistics, factor analysis, Cronbach＇s alpha, structural equation modeling, and multi-group structural analysis methods were used in this study. The results confirm that customer experience management impacts to customer loyalty shopping at supermarkets. There are six components of customer experience management including brand name, space, commodity, staff, parking lot, and the presence of other stores in supermarkets. In particular, the commodity composition has the strongest impact on customer experience management and satisfaction and directly influences on customer loyalty. In addition, elements of customer experience management affect customer loyalty indirectly through sensory experience, social experience, and satisfaction. The results of multivariate analysis show that age group, spending per shopping at supermarkets, and marital status of the client do not change the relationships in the research model. Meanwhile, the relationship of the different models of the client group income, gender, education, occupation and customers is different. This study adds value to consumer behavior and customer experience management literature.

Coffee is a significant industry, accounting for 3% of Vietnam’s GDP, with annual export turnover consistently exceeding USD 3 billion. Despite global economic challenges affecting purchasing power at various times, Vietnam’s coffee exports in December 2023 continued to surge, reaching the highest level in the past 9 months at 190,000 tons, a 59.3% increase compared to November 2023, but still a slight 3.5% decrease from the same period last year. The export turnover reached USD 538 million, a 51% increase from November 2023 and a 26.4% increase from the same period last year. Therefore, forecasting the coffee export volume holds significant importance for coffee producers nationwide. This research employs the Box-Jenkins method to construct an ARIMA model for forecasting Vietnam’s coffee export volume based on annual data published by the General Statistics Office. Results indicate that among the models considered, the ARIMA(1, 1, 2) model is the most suitable. The study also provides short-term forecasts for Vietnam’s coffee export volume. However, the current model is limited to forecasting and is not yet optimized, as the assumed linearity in the model is a simplification.

This paper reports some results of geo-scientific evaluation of the petroleum systems in the northeastern area of the Song Hong Basin offshore Vietnam. Geological-geophysical data, including regional studies, 2D and 3D seismic ＆ logging interpretation results as well as core/cutting samples analysis were integrated to reveals that the north-eastern area were controlled by pull apart activities along Song Hong river fault system, rifting phase during Eocene-Oligocene and subsidence during Miocene-Quaternary. Inversion activities at the end of Oligocene and late Miocene also play very important roles. These activities convert Pre-tertiary carbonate basement rocks to be potential reservoirs. The main source rock, overlying and adjacent to basement highs, was deposited in the lacustrine environment during rifting phase of Eocene and Oligocene and is still at the depth of oil generation window. The mentioned source rock layer is also considered as a good top seal for the basement. Petroleum system has been proven by the drilling and testing results and the studied area become more attractive and have higher chance of success.
