Abstract

This study estimated and decomposed the productivity changes into technological change and efficiency change components for the photonics industry and examined ways of imporving the productive efficiency. Unlike most previous studies, this study employed a non-oriented Malmquist productivity index, which is a non-radial method and deals directly with the input surpluses and output shortfalls. The empirical results show that the productivity of the photonics industry has increased. The main reason for this is the increase in technical efficiency. In addition, there was a statistically significant difference in the productivity changes according to the firm's geographic location and participation in government support programs. These findings suggest that the government's regional strategic industry promotion policy has contributed to improvements in the productive efficiency of photonics industry. The approach presented in this study could be used as a practical reference guide to help enhance the competitiveness of the photonics industry.

본 연구는 지역전략산업인 광산업을 중심으로 생산성 변화를 추정하고 이러한 변화를 기술변화 요인과 효율성변화 요인으로 분해함으로써 광산업의 생산효율성 향상 방안을 모색한다. 특히 기존의 연구들과 달리 투입최소화와 산출최대화를 동시에 고려하고 아울러 투입요소와 산출물의 잔여를 모두 반영할 수 있는 비방사적 비지향적 맘퀴스트 생산성지수를 분석에 활용한다. 실증분석 결과, 광산업의 생산성은 증가한 것으로 나타났으며, 이러한 생산성 증가는 주로 기술적 효율성 증가에 기인한 것으로 분석되었다. 또한 정부지원사업 수혜 여부와 지리적 입지에 따라 생산성 변화에 통계적으로 유의미한 차이가 있음을 확인하였다. 이와 같은 결과는 정부의 지역전략산업 육성정책이 광산업의 생산효율성 향상에 기여하고 있음을 시사하는 것으로 향후 광산업의 경쟁력 제고에 도움이 되는 실질적인 참고자료로 활용될 것으로 기대된다.
