This study analyzes the expense structure of the air transport industry, based on the cost and income data of 18 major airlines, estimates the economic effectiveness of scale and conducts comparative analysis. As for the method of analysis, Translog cost function and the Fourier flexible function were used. The result showed that big companies had the economy of scale based on the Translog cost function, while the Fourier flexible function led to a estimation that expanding the input is not recommended, for the expansion of scale entails the poor economy of scale. It can be presumed that the economy of scale was estimated according to the U shape of the Translog cost function in the given data. On the other hand, the Fourier flexible cost function approaches the unknown function, as it is a Fourier series, and correctly infers the economy of scale based on the analyzed data. As for the flag carrier's economy of scale, it was inferred that the economy of scale existed by any of two functions. Therefore, the conclusion was that further expanding the scale will not cause any problem.

본 연구는 최근 빈번하게 진행되고 있는 국내 의료서비스기관들의 대형화 및 집단화 움직임에 대하여 동 산업이 규모 또는 범위의 경제(Economies of Scale and Scope)를 실현할 수 있는지를 전위로그비용함수 추정을 통하여 분석하였다. 추정결과 계수에 따라 다소 차이는 있지만 여타 서비스의 생산수준의 변화에 의해 영향을 받는 특정 서비스 생산의 한계비용을 나타내는 계수들 모두 통계적으로 유의함을 보였다. 추정된 단일생산물 규모의 경제(Single-Product Scale Economy: SSE)계수들 뿐만 아니라 전반적인 약 규모의 경제(Ray Scale Economies: RSE)값 모두 1보다 작은 수치를 나타남으로서 한국 의료서비스기관들의 서비스생산에 규모 경제가 존재함을 보여주었다. 범위의 경제 존재여부의 분석을 위한 상호 서비스생산에 있어서 비용의 상보성 추정에서도 모두 90% 이상의 통계적 유의수준을 보였다. 특히 외래환자와 입원환자 진료서비스 간, 입원환자 진료서비스와 제 증명서발급 및 기타 서비스 활동 간에 있어서는 범위의 경제뿐만 아니라 비용의 상보성이 존재함을 보여주었다.

The physical factor having a great influence among components of making values of profit model in apartment houses is equilibrium change of house and this study suggests an alternative of remodelling. It sets profit models including model dividing household of large scale into that of small scale using value making factor of apartment house and spatial composition techniques and model integrating households of small scale and converting them into those of large scale and finds that its economy is good as over 'average', evaluative value of economy is reduced as discount rate increases and economy of remodelling is superior.

This Paper investigates imperfect competition and economy of scale on Korean energy markets based on computable general equilibrium model. Some industries like energy sector have exhibited that their economies have strong economies of scale and imperfect competition. Thus these industrial organization facts should be incorporated into CGE model. In our model, non-competitive markets are adopted and compare these results with convention perfect competition model.

The aim of synchronization of production and transportation planning in the supply chain is to increase the flexibility and to decrease various costs. The suggested model in this study synchronizes the timing to supply to a downstream manufacturer directly after production and to be consumed in a downstream manufacturer right after receipt. This model deals with the frequent delivery in small amount which is a new trend of the transportation not governed the economy of scale principle. Moreover, various types of transportation governed by the economy of scale principle or not are considered. Then, the two-phase mathematical model is suggested to obtain optimal job sequence and production quantity for each tasks. But, it is difficult to gain optimal solutions if there is a transportation governed by the economy of scale principle in the supply chain, or the size of the problem is increased. Thus, heuristic algorithms based on simulated annealing and genetic algorithm are suggested to find good solutions in the reasonable time.

Liberalization may be described as the opening up of the economy to the outside world by relaxing government trade and economic policy restrictions to allow imports. In Kenya, this took place in the early 1990s and it had negative and positive effects on businesses manufacturing and retailing clothing and textiles. This case study narrates what has happened over the last 20 years to businesses in Nairobi, Kenya dealing in clothing and textiles. Some of the original businesses have closed down and been replaced by new ones. More small scale Kenyan businesses have been started dealing in clothing imports from the East and West selling both new and second hand clothes. There has been increased employment in the small scale clothing and textiles sector in garment making and retailing. All in all, liberalization has forced large and medium scale textile manufacture to change strategy so that they target selling to the export market more than to the local market.

Social and economic development needs the support of transportation and communications and in turn the development level of society and economy affects urban traffic demand and determines the investment scale of transportation facilities. In the paper based on the analysis of the evolution of urban transportation in Shanghai in the past ten years and the economic background of that period, the urban transportation in the future development of economy is generally prospected.

공동주택 수익모델의 가치를 형성하는 요소 중 영향도가 큰 물리적 요소는 주택의 평형변화로서 이를 중심으로 리모델링의 대안을 제안한다. 이에 따라 본 연구에서는 공동주택의 가치형성요인과 공간구성기법을 이용한 큰 평형의 세대를 작은 평형의 세대로 분할하는 모델과 작은 평형의 세대를 통합하여 큰 평형의 세대로 변환하는 모델의 수익모델을 설정하여 경제성은 '보통'이상 '양호'한 것으로 나타났으며, 경제성 평가값은 할인율이 증가함에 따라 감소하며 리모델링의 경제성이 우수해지는 것으로 나타남을 알 수 있다.
