글로벌 Malmquist 생산성지수를 활용한 의료기기 수출제조기업의 생산성변화 분석

Productivity Change Trend Analysis of Medical Device Export Manufacturers Using the Global Malmquist Productivity Index

Purpose - The purpose of this study is to analyze the trend of productivity changes of medical device export manufacturers by using the global Malmquist productivity index. Design/methodology/approach – The global Malmquist productivity index was used in this study. In the productivity analysis, total assets, equity, tangible assets, intangible assets, employment costs, selling expenses, and general administrative costs were used as input variables while sales and gross profit were used as output variables. Data for this empirical analysis were obtained from 128 medical device manufacturers for a period of six years from 2013 to 2018 using the KISVAUL DB. Findings - The results of this study are as follows: First, the productivity of medical device manufacturers declined by 2.3% every year for six years due to pure technical efficiency change and best practice gap. Second, during the same period, productivity of exporting firms declined by 2.5% per year, while non-exporting firms experienced an average annual decline of 2.2%. Third, corporate group productivity and stand-alone firms’ productivity declined 2.3% each year over the same period. Fourth, productivity of large-sized firms increased by 1.8% per year, while that of small and medium-sized firms decreased by 0.3% per year. Research implications or Originality - Exporting firms should improve productivity by enhancing their pure technical efficiency and promoting technological progress.
