경영활동의 효율성과 조세회피의 관련성

This paper investigates the relationship between firms’operational efficiency and tax avoidance. The sample comprises manufacturing firms listed on the Korean Stock Exchange Market over the period 2002 - 2013. To examine the tax avoidance propensity of firms, we rely on the measures of tax avoidance drawn from prior research. Specifically, we measure the tax avoidance propensity based on the residual book－tax difference suggested by Desai and Dharmapala (2006). Operational efficiency includes technical, pure technical, and scale efficiencies evaluated adopting nonparametric data envelopment analysis (DEA). We hypothesize a positive relationship between firms’operational efficiency and tax avoidance. The manager of an operationally efficient firm will minimize the cost of resources consumed in revenue-generating activities, and reduce cash expenses as much as possible. Managers will strive hard to save their firms’tax payment which is one of the major cash expenses. As expected, our empirical result shows that firms with higher operational efficiency are statistically associated with higher tax avoidance. This study contributes to the research stream by providing empirical evidence that firms' operational efficiency can affect the level of tax avoidance.
