본 연구는 과잉투자(過剩投資)나 과당경쟁(過當競爭)이 발생할 수 있는 객관적인 기준과 경제적 조건들을 분석하고, 정부규제(政府規制)의 근거로서 제시되는 과잉투자(過剩投資)-과당경쟁(過當競爭)의 개념과 논리의 타당성 및 이에 대한 정책적(政策的) 대응방향(對應方向)을 검토하였다. 본고(本稿)에서 필자(筆者)들은 유지불가능한 자연독점의 경우를 제외하면 시장수요(市場需要)의 사전적(事前的) 불확실성(不確實性)으로 인해 발생하는 사후적(事後的) 설비부족(設備不足)이나 유휴설구(遊休設構)는 발생할 수 있지만, 투자시점에서의 과잉투자는 발생할 수 없음을 모형의 분석을 통해 보였다. 설비투자 완료후 생산(生産)-판매단계(販賣段階)에서 유휴설비가 발생하였을 경우에 정부(政府)가 경쟁을 제한할 수 있다는 예상이 오히려 과잉설비투자를 초래하는 중요한 원인임을 보이고, 일관성 있는 정부불개입정책(政府不介入政策)의 유지가 과잉설비투자를 억제하는 최선의 정책임을 보였다.

The purpose of this research is to investigate the relationship between job creation and ICT usage in service industries. This research is particularly important because job creation is one of the most critical issues for the country. With technology innovation and system integration, manufacturing industries do not create enough employment, therefore, the society relies on service industries for creating job opportunities. Until now, due to limitations, analysis of job creation in service industries through ICT usage has not been investigated in depth. Thus, development of an effective ICT support policy was impossible. In this research, we used seven methods to investigate overall relationship between ICT usage level and job creation. A rule of large numbers has been applied to reach conclusion. Through this research, the government can focus its investment on service industries where job creation rate is the highest. We can expect both reinforcement in competitiveness of our service industry and continuous creation in employment, eventually leading to a virtuous cycle.

We consider a continuous time surplus process with investments the sizes of which are independent and identically distributed. It is assumed that an investment of the surplus to other business is made, if and only if the surplus reaches a given sufficient level. We establish an integro-differential equation for the distribution function of the surplus and solve the equation to obtain the moment generating function for the stationary distribution of the surplus. As a consequence, we obtain the first and second moments of the level of the surplus in an infinite horizon.

Vast amount of information is generated and shared in this active digital As the digital informatization is vividly going on now, most of documents are in digitalized forms, and this kind of information is on the increase. It is no exaggeration to say that this kind of newly created information and knowledge would affect the competitiveness and the future of our nation. In addition to that, a lot of investment is being made in information and knowledge based industries at national level and in reality, a lot of efforts are intensively made for research and development of human resources. It becomes easier in digital era to create and share the information as there are various tools that have been developed to create documents along with the internet, and as a result, the share of dual information is increasing day in and day out. At present, a lot of information that is provided online is actually being plagiarized or illegally copied. Specifically, it is very tricky to identify some plagiarism from tremendous amount of information because the original sentences can be simply restructured or replaced with similar words, which would make them look different from original sentences. This means that managing and protecting the knowledge start to be regarded as important, though it is important to create the knowledge through the investment and efforts. This dissertation tries to suggest new method and theory that would be instrumental in effectively detecting any infringement on and plagiarism of intellectual property of others. DICOM(Dynamic Incremental Comparison Method), a method which was developed by this research to detect plagiarism of document, focuses on realizing a system that can detect plagiarized documents and parts efficiently, accurately and immediately by creating positive and various detectors.

The purpose of this research is to identify the relation between OFDI (Outward Foreign Direct Investment) and wage inequality. In order to analyze various effects of OFDI on wages depending on the types of workers, the research classified laborers into four categories: permanent/skilled worker, permanent/unskilled worker, temporary/skilled worker, and temporary/unskilled worker. With controlling wage-determining factors such as education, labor union, individual fixed-effect, and industry-level effect, this paper examines whether OFDI attributes to the wage inequality among each type of workers. Moreover, this study also analyzes possible effects on wages that could vary according to the different characteristics of investments by classifying OFDI into two groups: OECD and non-OECD. The results reveal that OFDI makes certain differences according to skill-intensity and contract type in terms of influences on wages. It also shows that the effect of OFDI on wages is more subject to contract type than to skill-intensity. The classification of OFDI into OECD and non-OECD proves that effects on wages can vary by characteristics of the subject of investment.

Education has been emphasized as one of tools of realizing social equality, which has its base on the ideology of equal education opportunity. The Opportunity level of adult education is important in the meaning of social equality. but these days It is being inequality. so The objectives of this study were 1) measuring the opportunity level of adult education in Korea, 2) analysing the difference adult education level by gender, regions, 3) making out the gap of the its level by social educational agencies, 4) to suggest the way to improve the opportunity level of adults educations between adults by gender, regions. The followings are the results from the study: Adult education participation level were lower. Adult education participation level per adult education type showed higher participation at private institutes, lower at cultural center of community and school's human and material resources are not properly utilized in adult educational activities. By adult education participation level per gender and location, women have a higher participation level then men, and urban areas have a higher participation level then rural areas. In case of location, environment variables is most explanatory in adult education participation level. To strive for methods to activate school-oriented adult education activities and to develop political solution to ease the resources gaps for adult education investment among regions in order not to deepen environment gaps of adult education between urban and rural areas. For adult education activation, institution and bodies in charge of adult education should expand and discover hardware and develop and distribute software. Also, adult education specialists who operate and manage these hardware and sofeware efficiently should be recruited.

The notion of productivity has been extended from the quantitative change of input factors to the efficiency change meaning efficient use of resources, and to the technical change meaning the qualitative improvement of input resources. In this way, the technical change is termed as total factor productivity in the individual businesses or the manufacturing industries. They should efficiently respond to the variations of economic environment and at the same time, have to make the efforts to improve productivity by increasing managerial efficiency and rasing the level of technology change for the continuous growth. Considering the growing importance of productivity, this study closely examines the factors influctuation on the productivity, fluctuation using total factor productivity in korean manufacturing industries. For the objective this study investigates the methods of measurement about total factor productivity, establishes the hypotheses based on the preceding research and finding. The results are obtained through the examination on the outcoms of regression analysis and related data. The results can be summarized as follows, First, in the progress of korean industrialization, the qualitative growth does not depend on the total factor productivity of the technical advance, and does not lead to the industry expansion. That is, the contribution of total factor productivity turns out to be relatively low. Second, it is necessary for the manufacturing industry to improve the level of technology and to emphasize the innovation of business, since the capital investment does not completely become fixed in the growth rate of productivity. Finally, continuous R&D investment should be made to increase total factor productivity. Namely, the regulation of industrial structure with an intensive technical development is essential and should be based on scientific and technical knowledge.
