Abstract

This study was conducted to analyze the industrial concentration of the districts, cities and counties among clinics, dental clinics, and Oriental clinics. For this purpose, the sales from 1996 to 2015 in five-year intervals were analyzed by the Heifindal-Hirschmann index (HHI). The results of this study showed that the competition index represented by the HHI tended to intensify as a whole. Especially in the county area, HHI tended to be in comparison with other regions, but decreased with statistically significance. On average, the HHI was higher in the county than in the district and city areas. In the case of the clinic, the HHI of the county area tended to decrease. In the case of the dental clinic, the HHI tended to decrease in the city and county, while in the Oriental clinic the HHI tended to decrease in the district, city and county. Overall, monopolies were present in the county, but competition strengthened over time. In the case of clinics, competition is intensifying in country. area. In the case of dental clinics, competition in the city and country areas has not yet reached saturation. In the case of Oriental clinics, competition in all regions has not yet been saturated, and competition in the distinct market has been most intense.

본 연구는 의원, 치과의원과 한의원에 대한 시군구 지역의 산업집중도 분석을 목표로 하였다. 이를 위해서 1996년도부터 2015년까지 5년 단위의 매출액을 허핀달-허쉬만 지수(HHI)로 분석하였다. 본 연구에서 도출한 결과는 HHI로 대표되는 경쟁지수에 대해서 전 지역에서 경쟁이 심화하는 경향을 보였다. 특히 군 지역은 HHI가 다른 지역에 비교해서 상대적으로 높으나 통계적으로 유의미하게 값이 줄어드는 경향을 보였다. 시군구에 있어서 평균적으로 군 지역이 구 지역과 시 지역과 비교하면 HHI가 높으며 의원의 경우 군 지역의 HHI가 지수가 높기는 하지만 감소 경향을 보였다. 치과의원의 경우에는 시지역 및 군 지역에서는 HHI가 감소 경향을 보였으며 한의원의 경우에는 구 지역, 시 지역 그리고 군 지역 모두에서 HHI가 감소 경향을 보였다. 전반적으로 의원급 기관에서 농어촌 지역이 독점적인 시장형태를 보였으며 시간이 지남에 따라서 경쟁이 증가하고 있음을 보여주었다. 의원의 경우에는 농어촌 지역 의원의 경쟁이 심화하고 있음을 나타내고 있으며 치과의원의 경우에는 도시 및 농어촌 지역에서의 경쟁은 아직 포화상태에 이르지 않음을 보여주었고 한의원의 경우에는 모든 지역에서 경쟁이 아직 포화하지 않은 시장이며 대도시 시장의 경쟁이 가장 심함을 보여주었다.
