본 논문은 세계 자동차시장의 단일화 현상과 규모의 경제라는 특성을 반영하는 독점적 경쟁시장 모형을 개발하여 환경규제의 효과를 분석하는 것이다. 이를 위하여 Dixit and Stiglitz의 모형과 규모의 경제가 반영된 레온티에프 생산함수를 이용한 독점적 경쟁시장모형을 설정하여 연비규제와 환경세 부과가 시장에 미치는 효과를 비교분석하였다. 분석결과 연비규제는 시장균형가격을 상승시키고, 개별 기업의 판매량은 한계비용증가율과 고정비용증가율의 크기에 의해서 결정되며, 기업의 수는 소비자의 소득에서 완성차에 대한 지출비중증가율과 고정비용증가율의 크기에 의해서 결정되는 것을 알 수 있다. 그리고 시장 전체의 총판매량은 고정비용증가율에 관계없이 지출비중증가율이 한계비용증가율보다 크면 증가한다. 한편 종량세 형태로 환경세가 부과되는 경우 균형가격은 상승하고 각 기업들의 판매량은 감소하는 반면 기업의 수는 변화가 없다. 연비규제와 환경세의 효과를 비교하기 위해서 양 정책수단의 한계비용 증가효과가 같도록 설정할 때 환경세가 연비규제보다 개별 기업과 산업 전체의 판매량 감소에 대한 효과가 더 크다. 그러나 연비규제로 인한 완성차에 대한 지출비중의 변화율이 고정비용의 증가율보다 크면 환경세 부과로 인한 기업의 퇴출효과가 연비규제의 경우보다 크게 된다.

우리나라 정부의 '06년도 연구개발예산은 8조77백억원 규모로 25년 사이에 670배 증가하였으며, 그 증가율도 지난 10년간 10%대를 유지하였다. 정부의 연구개발예산 또는 연구개발보조금이 증가함에도 불구하고 정부 연구개발 보조금이 민간 자체 연구개발 투자에 미치는 영향에 대한 연구는 많이 이루어지지 않았다. 본 연구는 정부 연구개발 직접보조금이 기업의 연구개발 투자를 진작 또는 대체 시키는지 여부 및 기업유형, 인종별 정부의 보조금 효과가 달라지는가에 대해 Propensity score matching (PSM)방법을 이용하여 실증 분석하였다. PSM 분석결과 정부의 연구개발 보조금을 받은 기업은 받지 않은 기업보다 연구개발 투자를 평균적으로 7억33백만원 더 지출하였으며, 세부적으로는 대기업과 서비스업의 보조금 수혜기업이 연구개발투자 지출을 더 많이 하였다. 이러한 결과는 정부의 R&D 지원 정책이 기업 특성 등에 따라 보다 맞춤형으로 전환될 필요성이 있다는 점을 보여주고 있다.

The National Health Insurance Expenditure has been increased rapidly since the introduction of the separation of prescription and dispensing in 2000, and this trend of rapid growth in overall spendings rate has been observed predominantly among medical practitioners. This study was conducted to investigate the growth rate and distributional changes in private medical practitioners' expenses from 1999 to 2002 and its determinants using the National Health Insurance claims data. The total increasing rate of all medical practitioners' expenditure paid by the National Health Insurance between 1999 and 2002 was $41.71\%$, which exceeding that of general hospitals by $20\%$p. But the income distribution among each practitioner was improved as the changes in Gini coefficient(from 0.40 to 0.38) and decile distribution ratio(from 0.25 to 0.29) during the same period showed. However, this improvement in distributional patterns is not enough since even in 2002 it turned out that the highest $10\%$ income group earned 33times more than the lowest $10\%$ income group did. Also, higher Gini coefficient was observed in larger cities and some department like plastic surgery, obstetrics and gynecology. The major causes of this differentials in medical practitioners' expenses were factors related to medical demand like proportion of old population, residential economic status in a given area. In addition, providers' economic incentives also played an important role in determining their income distribution. The large income differentials among physicians may imply a skewed distribution of patients and thus long waiting time, inefficient utilization of resources and potential inadequate quality of care. In this sense, unreasonable distributional gaps should be reduced, so effective measures as well as ongoing monitoring would be necessary to correct current distributional problems.

Korea's healthcare is in great danger of sustainability. In 2020, the baby boomer will begin to be older, and there is no promise that the total fertility rate of 1.0 or less will rebound, and Korea's economic growth rate is predicted to be less than 2%. Together with these phenomena, Plan for Benefit Expansion in Nation Health Insurance (Moon Jae-in Care) will seriously threaten the sustainability of health insurance finance. In addition, health care in Korea has many problems: excessive medical utilization, rapidly increasing elderly medical costs, concentrating patients into big hospitals, low healthcare personnel but many healthcare facilities and equipment, bad quality of primary and mental care, and fast-growing health expenditure. For sustainability, healthcare of Korea should be reformed. The direction of the reform is people-centered and integrated healthcare in the community which is composed of empowering and engaging people, strengthening governance and accountability, reorienting the model of care, coordinating services, and creating an enabling environment.

The objectives of this study was to analyze the major causes of decreasing utilization rate of health care institutios in pilot-project area of regional medical insurance, Kwang-hwa and Kun-wi country. After the implementation of medical insurance, utilization rate of health institutions turned out' to be lower than it was estimated, when the pilot-project of regional medical insurance was planned. It might be due to changes in inhabitant's behavioral attitude toward medical insurance. So this study was made to find measures for financial stability by increasing utilization rate of health care institutions and to be available for basic demand-supply program of medical care. The hypothesis of this study was as follows; First. there is difference in understanding health care institutions between Kun-wi and Kwang-hwa. Second. respondesnts of inquiry survey have exact knowledge of their past experience of treatment taken prior to enforcement of medical insurance, Questionaire survey was made as to each 700 household among total 11, 884 households in Kun-wi and 20,919 households in Kwang-hwa. In case of Kun-wi, 70% of inquired households (491) gave their answers. In Kwang-hwa, the number was 560 households (80% of inquireds). Dollected data was processed and analyzed by way of using SPSS batch system. To evaluate facto rs distribution aspects of data and to make comparison between two area, percentage and $X^2$ distribution were applied. The results were as follows; L The utilization rate of health care institutions in Kun-wi and Kwang-hwa was lower than it was estimated. when pilot-project of medical insurance was planned. 2. Prior to the implementation of medical insurance. inhabitants in two area chose the medical institutions considering such factors. First was medical care fee cheap. second in habitant's residence, Third was the institutions conveniently easy of access. 3. After the implementation of medical insurance. 26.1% of inqurieds in Kun-wi and 41.6% in Kwang-hwa, changed medical institutions. In case of Kwn-wi, from health care institution (p 0.05), and in case of Kwang-hwa, vice versa, from general medical institutions to health care institutions. 4. Evaluation by factors were made such as follows. Inquired gave high marks to following facts: In case of Kun-wi, general medical institutions were difficult of access and relation between patients: was not friendly, but burden of medical expenditure was light. Effects of treatment and facilities was good. In case of Kwang-hwa, inquired gave high evaluation marks to the follow ing facts; facilities of medical institutions was not good, but the burden of medical expenditure was light. 5. After the implementation of medical insurance, the services was evaluated as good, but inquired hopec for lessening the burden of medical expenditure. 6. In case of exact understanding of cost-sharing, the evaluation rate in Kwang-hwa was higher than that of Kun-wi (p < 0.005). And positive attitude toward necessity of medical insurance was also good in Kwang-hwa (p < 0.05). 7. In case of inquired's attitude toward medical institutions, Kwang-hwa showed positive response (p < 0.05) 8. In the case of comparison between general medical institution and health care institution, two area showed similar positive response; medical manpower, facilities of medical institutions and effest: of treatement was good. 9. In comprehensive evaluation of benefit-service; the general medical institution's positiveness was higher than that of health care institutions in Kun-wi. But in Kwang-hwa vice-versa. 10. If the medical expenditure of general medical institution and health care institutions was equal 77% of inquireds in Kun-wi and 59.1% in Kwang-hwa answered that they chose general medical insurance. Considering results above mentioned, the conclusion of this study was made as follows. 1. In Kwang-hwa county, where the understanding of health care institutions's was good, the utilization's of health care institutions was shown high. Therefore, in case of Kwang-hwa, betterment: should be made to induce increasing utilization rate for negative factors of health care institutions. 2. In case of Kun-wi, where the understanding of health care institutions was on the decrease, measures for changing such negative factors should be taken by way of strengthening public relations. And cases of Kwang-hwa should also be studied. 3. On the side of financial stabilization and establishing health care delivery system, primary health care should be available. Therefore, the major cause of inhabitant's avoiding health care institutions should be known. And measures for activating that institutions have to be taken. So, the facilities of health care institution have to be improved up to the level of clinic. And supportive measures for securing equipment and improving health care services should also be taken. It is necessary that strategy for public relations should be employed with policy considerations and supports.

This study was an attempt to encourage the development of a rehabilitation delivery system and programs as a substitute service for hospitalization on the case of car accident patients, such as hospital based home health care nursing services. Various substitute services for hospitalization are required to curtail the length of stay for inpatients who were hospitalized with car accident compensation insurance. It focused on developing an estimation an early discharge day for car accident inpatients based on detailed statements of treatment for 111 inpatients who were hospitalized at the General Hospital in 1997. This study had four specific purposes as follows. First. to find out the utilization of medical services. Second, to estimate the time of early discharge and income increasing effect based on early discharge for those patients. Third, to identify the factors affecting total medical expenditure and the length of stay for those inpatients. Forth, to figure out the need of utilizing home health care nursing service for accident patients. In order to analyze the length of stay and medical expenditure for inpatients who were hospitalized due to car accidents, the authors conducted micro- and macro-analysis of medical and medical expenditure records. Micro-analysis was done by nominal group discussion of 4 expertise with the critical criteria, such as a decrease in the amount of treatment after surgery, treatments, tests, drugs and changes in the test consistency, drug methods, vital signs, start of ROM exercise, doctor's order, patient's outside visiting ability, and stable conditions. In addition to identifying variables affecting medical expenditure, and the length of stay and income effect due to early discharge day, the data was analyzed with a multiple regression analysis and linear regression analysis model by SPSS-PC for windows and Excell program. Results of this study were as follows. First. the mean length of stay was 50.3 days. whereas the mean length of stay due to early discharge was 34.3 days at the hospital. The estimation of time of early discharge depended on the length of stay. The longer the length of stay, the longer the length of time of early discharge : for instance a length of stay under 10 days was estimated as correlating to a mean length of stay of 6.6 days and early discharge of 6.5. The mean length of stay was 217.4 days and the time of early discharge was 110.1 respectively. The mean medical expenditure per day was found to be 169.085 Won and the mean medical expenditure per day showed negative linear trends according to the length of stay at the hospital. The estimation results of the income effect due to being discharged 16 days early was around 2,244,000 won per bed. However. this sum does not represent the real benefits resulting from early discharge, but rather the income increasing amount without considering medical prime cost in the general hospital. Therefore, further analysis is required on the cost containments and benefits as turn over rate per bed as the medical prime costs. The length of stay was most significant and was positive to the total medical expenditure, as expected. Surgery and patient's residential area was also an important variable in explaining medical expenditure. The level of complications was the most significant variable in explaining the length of stay. There was a high level for need a home health care nursing service which further supports early discharge for accident patients. In addition, when the patient was discharged. they needed follow up care for complications suffered during the car accident. $86.8\%$ of discharged patients responded that they needed home health services after early discharge. From these research findings, the following suggestions have been drawn. Strategies on a health care delivery system must be developed in order to focus on the consumer's needs and being planned for 21 century health policy in Korea. Community based intermediate facilities or home health care should be developed for rehabilitation services as a substitute for hospitalization in order to shorten the length of stay would be. A hospital based home health care nursing service. it would be available immediately to utilize by patients who want rehabilitation services as a substitute for hospitalization with the cooperation of car insurance companies.

본 연구는 복지국가의 재정건전성 담보에 노동시장정책 확충이 기여하는지를 실증적으로 규명하는 연구이다. 구체적인 분석은 20개 OECD 국가들의 1985년부터 2015년까지의 자료를 토대로 결합시계열 회귀분석과 Baron과 Kenny(1986)의 단계적 매개효과 검증을 통해 이루어졌으며, 분석의 강건성 확인을 위해 시스템 동적패널분석을 추가 수행하였다. 분석모형을 설정함에 있어 본 연구에서는 기존 연구에서 간과되어온 두 측면, 노동시장정책 성과들 간의 선후 관계와 노동시장정책의 상호작용 효과를 반영하였다. 분석결과 노동시장정책은 복지국가의 부채 수준에 유의미한 영향을 미친다. 이때, 적극적 노동시장정책은 고용률을 매개하여 국가 부채 수준을 효과적으로 낮추는 것으로 나타난다. 반면에, 소극적 노동시장정책은 고용률 제고 기능을 하지 못하는 것은 물론 단기적으로는 국가 부채 부담을 늘리는 경향도 있다. 다만, 이것의 영향은 적극적 노동시장정책과 결부되면 부적 영향이 상쇄되는 것으로 나타난다. 즉, 단기적으로 노동시장정책 지출 확대로 재정수지가 악화될 수는 있지만, 장기적으로 이는 고용률 제고 효과를 통해 복지국가의 재정건전성을 담보하는 데 효과적인 역할을 수행할 수 있는 것으로 보인다.
