Abstract
The purpose of this study is to analyze the efficiency and productivity changes of the tourism industry and 7 sub-industries and to diagnose the efficiency of the tourism industry accordingly. This study analyzed the change indices of efficiency and productivity indices through data envelopment analysis and malmquist productivity index for 2010-2017 The census on Basic Characteristics of Tourism Establishments. In terms of efficiency by sectors, overall technology efficiency, pure technology efficiency, and scale efficiency improved. However, the tourism hospitality and lodging industry is experiencing an Increasing Return to Scale(IRS) phenomenon. Malmquist productivity index trend is analyzed as the Total Factor Productivity Index(TFPI) improved in 2017 compared to 2010. before 2014-15 year, Technical Efficiency Change Index(TEI or TECI) was contributed to the improvement of TFPI, and after 2014-15 year, Technical Change Index(TCI) was contributed to the improvement of the TFPI. The TFPI of the tourism industry is constantly improving, but the TFPI is somewhat lower than 1 in 2016-17. However, there is needed to improve the return to scale(RTS) by actively responding to technological change and improving overall operating efficiency.
