Measuring the Scale Efficiency of Agricultural SMEs Exporting in Vietnam

The paper uses data envelope analysis model to measure the scale effect of agricultural SMEs exporting in Vietnam in the period of 2010 - 2015 and use the Tobit regression model to assess the impact of factors such as region, domain, inventory, salary, capital, tax to affect the scale of enterprises in research. Results from the model show that in the 2010-2015 period, the number of enterprises reaching the optimal scale is very small. Businesses operating at the increasing return to scale accounted for more than 90%. In addition, enterprises operating in an efficient scale are mainly in the Southern region, factors such as wages/labor and capital/labor ratio have a positive impact and tax and survival factors. The warehouse has a negative impact on the scale efficiency of businesses. Since then, the author analyzes and draws conclusions and some policy recommendations for the Government and small and medium-sized agricultural exporters.
