enterprises TFP : Total factor productivity UK: The United Kingdom ABSTRACT Using panel data from Vietnamese Small and Medium Enterprises Survey from 2004 to 2010, this study aims to examine the relationship between financial constraint and firm total factor productivity of small and medium enterprises (SMEs) in Vietnam To achieve this objective, this study measures the total factor productivity of the SMEs Then, this study identifies the relationship between financial constraint and total factor productivity of SMEs Levinson-Petrin approach is used in order to calculate the total factor productivity of firm in the first step In the second step, an estimation model is built to examine the linkage between financial constraint and firm total factor productivity The research finds that there is relationship between financial constraint and firm productivity For example, the relationship between firm leverage and total factor productivity of firm is positive It means that access to large external finance can help a firm ease the degree of credit constraints, thereby increasing its capacity and survival in the market Secondly, liquidity ratio does not have significant impact on firm productivity in Vietnam Thirdly, firm size and firm age have positive relationship with firm productivity In other word, firms with larger size and older will have higher productivity Finally, firms join in export activities are found to get higher productivity than the others TABLE OF CONTENTS Chapter 1: INTRODUCTION 1.1 Problem statement: 1.2 Research objective: 1.4 Research

result shows that there is no significant correlation between independent variables The maximum correlation score of 0.44 is the correlation between Leverage and Liquidity Furthermore, the variance inflation factor (VIF) in this table is relatively low, compared to the bench mark of 10 which is an evidence of 28 the presence of multicollinearity in data This result indicates that the multicollinearity problem is not significant in this study Because the data is the short panel data, serial correlation is not a problem and it can be excluded However, the heteroskedasticity should be included in this study 4.2.2 Regression result Table 4.5 shows the estimation results Table 4.5.1: Regression result VARIABLES lnLeverage lnLiquidity lnSizeY lnAge Export Constant Observations
