  • This study attempts to analyze trade flows between Vietnam and China in order to understand the mutual influence of bilateral trade relations. China is a country with the world's leading economic potential. China and Vietnam are neighboring countries sharing a border of 1,281 km. Trade relations between the two countries are a necessity and, with a right policy, are beneficial to both. Vietnam has a trade deficit with China. This situation is exacerbated by the continuing rise in the gap. Vietnam trade deficit from China was USD12.5 billion in 2010, increasing to USD24 billion in 2018. Data are extracted from the 2015 national input-output tables of Vietnam and China as well as Vietnam Household Living Standard Survey statistics. The research identified 36 sectors of bilateral input-output trade between Vietnam and China. A bilateral output-input model is applied to analyze how final demand and use of input in the production of this country induces output and value added of the other country. The results show that China benefits more from Vietnam's production and consumption than Vietnam does. Vietnam's inter-sector structure does not stimulate domestic production due to the absence of supporting products as inputs in the production process.

  • The purpose of this study is to examine the determinants of intention to borrow consumer credit of Vietnamese people by applying the Technology Acceptance Model (TAM) and extending it with several variables, including anxiety, perceived trust, and perceived financial costs extracted and adapted from the existing literature. A questionnaire survey was administered in the big cities of Vietnam to a total of 602 consumers. Structural equation modeling (SEM) techniques have been employed to investigate the relationship among intention determinants to borrow. Findings show that perceived usefulness mediates the impact of subjective norms on the intention to borrow consumer credit. At the same time, subjective norms also directly influence the intention to borrow. Notably, anxiety, perceived trust, perceived financial cost, perceived ease of use have no significant influence on intention to borrow. Meanwhile, education level is confirmed to have a moderate influence on intention to borrow consumer credit of Vietnamese people. However, there is not enough statistical evidence about the influence of gender and marital status on the intention to borrow consumer credit in Vietnam. Based on the findings of the Vietnamese consumer credit market, we proposed some suggestions to promote the growth of the market in the future.

  • Currently, issues related to freight at Vietnamese logistics companies are becoming more and more urgent because of typical problems in Vietnam such as traffic, infrastructure, and application of information technology. This problem has been studied by applying many different approaches such as Integer Programming (LP), Mixed Integer Programming (MIP), hybrid, meta search, … In this paper, we applied the ILP model in order to deal with the VRP problem in a small size logistics company which is very popular in Vietnam. The experiments showed promising results with some optimal solutions with some small extra costs.

  • Two new species of Camellia (Theaceae) are described from Vietnam: Camellia vuquangensis Luong, Tran & L. T. Nguyen and Camellia hatinhensis Luong, Tran & L. T. Nguyen. The new taxa were collected from Vu Quang National Park in the center of Vietnam. The new finds are morphologically dissimilar to all known Camellia species. Recent Camellia discoveries have increased the number of species recorded in Vietnam from 50 to 75, making Vietnam a center of diversity and a crucial area for more research into the diversity and distributions of Camellia.
