4G has been developed in Vietnam for a long time with commitments to superior speed and interactions compared with 3G services from telecommunications service suppliers such as Viettel, VinaPhone, MobiFone, Gmobile. However, by now, the growth rate of 4G services in Vietnam still remains low and the services are not highly appreciated by users in comparison with some countries in the region and the world. It is therefore very necessary to identify factors affecting the decision to use 4G services. The article proposes a research model on factors affecting the decision to use 4G services of Vietnamese customers based on TAM model and previous research findings. The research model is set up to measure the factors affecting the decision to use 4G services of Vietnamese customers, so that suppliers can further develop their services to meet the demand of users and attract more customers. On the side of users, they can enjoy more conveniences that this advanced technology brings to their work, study and communication so as to raise their work performance and improve their quality of life.

The aim of this research is analyzing the audit expectation gap in Vietnam. The research result has identified that there are many differences between the auditors’ and the financial-statement users’ opinions about the auditors’ responsibilities. Most of research results about the auditors’ responsibilities show that the perception of financial-statement user regarding to auditors’ responsibilities has been higher than the auditors’, which is the reason for the wide audit expectation gap in Vietnam. Based on the research result, some reasons for the audit expectation gap are listed: the auditors have not fully performed their responsibilities based on the current regulations, the current standards on auditing have not been reasonable, and the most important reason is because the financial-statement users have high expectations (unrealistic expectations) of auditors’ responsibilities. Moreover, based on this research result, some related recommendations have been suggested and they are hoped to provide the useful references for the corporations, the government, auditors and fundraisers to enhance the quality of the financial statements and provide the useful information for the users.

The paper aims to test the impact of tax structure on economic growth in the localities of Vietnam. In the paper, it is assumed, that tax structure is measured through the annual growth rate of tax revenue of 63 provinces and cities of Vietnam in terms of three groups: consumption tax (CT), income tax (IT), and property tax (PT) during the period of 11 years from 2007 to 2017; the research data was collected from the General Department of Taxation of Vietnam. Economic growth is a dependent variable, represented by the annual growth rate of the gross domestic product of each locality with the data source from the General Statistics Office of Vietnam. With the regression analysis according to the GMM method, the research results showed that consumption tax (CT) and income tax (IT) had a positive impact on economic growth in the localities of Vietnam, and property tax (PT) was not statistically significant. In addition, the study has achieved great success by identifying the consumption tax components that had significantly positive impacts on economic growth (GDP), namely export and import taxes (CT1), value added tax (CT2); meanwhile, excise tax (CT3) had a negative effect on economic growth (GDP). For income tax, personal income tax (IT2) also had a positive effect on economic growth (GDP). The research results are the first empirical evidence in Vietnam on the impact of the tax structure on economic growth in the localities, which is important for the Government of Vietnam to have a basis to manage tax policies in order to stimulate economic growth in a sustainable manner

Modern corporate governance standards and principles is becoming vital issues in developing countries such as Vietnam, China, India, Indonesia, Myanmar, Bangladesh, etc. The 2006 Taiwan Conference on Corporate Governance showed current company system needs not only back-end CG solution such as “golden parachute” but also internal mechanisms.

Next, it separated independent contents with analysis and identified differences between these above set of standards which are and have been encouraged to use as reference principles for many organizations. In addition to, it aims to build a selected China comparative set of standards for corporate governance system in the post-crisis and scandal time. Last but not least, this paper illustrates some ideas and policy suggestions in order to overcome obstacles in China corporate governance system such as: insider trading, false financial reporting and concentration of state ownership.
