This paper conducted an indepth assessment on the efficiency of the impacts of trade agreements on rice exports during the period from 2000 to 2015. Based on the secondary data published by the General Statistics Office of Vietnam and the World Bank, the study employed random boundary gravity model to quantify the capacity of Vietnam to exploit rice export potential when participating in trade agreements, or in other words, to estimate the inefficiency in operation of rice export activities of Vietnam under the impact of trade agreements. The results show that rice export activities have not promoted well (at a low level) the impact of the trade agreements that Vietnam has participated in and not all trade agreements have a trend to increase the capacity to exploit rice export potential. Since then, this study provides some recommendations to improve the impact of trade agreements on rice exports in developing countries including Vietnam.

This study was conducted to measure the level of economic linkage in key economic zones in central Vietnam generally and to measure the level of economic linkage in the tourism sector. Secondary data were collected from the Statistical Yearbook published by the General Statistics Office and the Local Bureau of Statistics and primary data collected from surveys of 102 hotels and tourism firms in the center of Vietnam. We used the Moran Index (I) to quantify overall economic aggregation across the region and that scoring method was used to measure the degree of linkage in regional tourism. The results show that the level of overall regional economic linkages was very low and this was also relevant when analyzing the tourism sector in some areas of the center of Vietnam. Based on the results, some recommendations are given for strengthening economic linkages in key economic regions of Vietnam.

This study focuses on measuring the impact of trade agreements on Vietnam's rice exports based on secondary data sources produced by the General Statistics Office, the World Bank, and International Monetary Fund. Structural gravity model was employed for analyzing and quantifying the impact of trade agreements on rice export of Vietnam. The results show the impact of Trade Agreements on Vietnam’s rice exports is relatively low and not all Agreements bring positive effects. Based on the findings, we give some recommendations for Vietnam's rice export to adapt more to the contents and standards of the Trade Agreements and will be participating in the future.
