As the fastest growing office transaction volume in Korea, there's been a need for development of indicators to accurately diagnose the office capital market. The purpose of this paper is experimentally calculate to the office price index for effective benchmark indices in Seoul. The quantitative methodology used a Case-Shiller Repeat Sales Model (1991), based on actual multiple office transaction dataset with over minimum 1,653 ㎡ from Q3 1999 to 4Q 2019 in the case of 1,536 buildings within Seoul Metropolitan. In addition, the collected historical data and spatial statistical analysis tools were treated with the SAS 9.4 and ArcGIS 10.7 programs. The main empirical results of research are briefly summarized as follows; First, Seoul office price index was estimated to be 344.3 point (2001.1Q=100.0P) at the end of 2019, and has more than tripled over the past two decades. it means that the sales price of office per 3.3 ㎡ has consistently risen more than 12% every year since 2000, which is far above the indices for apartment housing index, announced by the MOLIT (2009). Second, between quarterly and annual office price index for the two-step estimation of the MIT Real Estate Research Center (MIT/CRE), T, L, AL variables have statistically significant coefficient (Beta) all of the mode l (p<0.01). Third, it was possible to produce a more stable office price index against the basic index by using the Moore-Penrose's pseoudo inverse technique at low transaction frequency. Fourth, as an lagging indicators, the office price index is closely related to key macroeconomic indicators, such as GDP(+), KOSPI(+), interest rates (5-year KTB, -). This facts indicate that long-term office investment tends to outperform other financial assets owing to high return and low risk pattern. In conclusion, these findings are practically meaningful to presenting an new office price index that increases accuracy and then attempting to preliminary applications for the case of Seoul. Moreover, it can provide sincerely useful benchmark about investing an office and predicting changes of the sales price among market participants (e.g. policy maker, investor, landlord, tenant, user) in the future.

School is a basic and the most fundamental facility of city planning just like other basic public facilities including the village office. Every plan is established on the basis of school. However, the problems such as the population reduction resulting from the nuclear family-zation and low birth rate, employment and welfare of the aged people resulting from "the old aged society", and the infant nursing and education resulting from a rapid increase of the working couples become notable and accordingly more requirements are being made. Reflecting this trend, the concept and operation system should be changed. Up to now, the BTL projects of the educational facilities are gaining a reputation of being efficient in terms of national budget running, but at the same time receiving negative reputation in terms of budget saving under the civil creativity and efficiency. Through upgrading the private sector investment projects into the BTO+BTL system and further into the BTO(Build Transfer Operate), we can accomplish the original goals of the private sector investment projects, and can make the education budget operation more efficient, and can greatly improve the education environments. However, we should not underestimate in this process that these facilities should not negatively affect the education environments. In any situation, the owners of schools are students.

In our study, we extracted the market, finance, and government factors determining R&D investment of individual firms in the IT industry in Korea. We collected the financial data of 515 individual firms belonging to IT and non-IT industries between 1980 and 1999 from the Korea Investors Service's database and investigated the empirical relationship between the factors using an ordinary regression model, a fixed effects model, and a random effects model. The main findings of our study are as follows: i) The Herfindahl Index variable representing the degree of market concentration is statistically insignificant in explaining R&D expenditures in the IT manufacturing industry. ii) Assets, which is used as a proxy variable for firm size, have a positive and statistically significant coefficient. These two results suggest that the Schumpeterian Hypothesis may be only partially applied to the IT manufacturing industry in Korea. iii) The dividend variable has a negative value and is statistically significant, indicating that a tendency of high dividends can restrict the internal cash flow for R&D investment. iv) The sales variable representing growth potential shows a positive coefficient. v) The subsidy as a proxy variable for governmental R&D promotion policies is positively correlated with R&D expenditure. This suggests that government policy has played a significant role in promoting R&D activities of IT firms in Korea since 1980. vi) Using a dummy variable, we verified that firms reduced their R&D investments to secure sufficient liquidity under the restructuring pressure during Korea's 1998 and 1999 economic crisis.

The purpose of this paper is to study the impact of trade openness on foreign direct investment (FDI) inflows into Vietnam, an emerging country with relatively high trade openness in recent years. The study used the vector autoregression (VAR) model to examine the impact of trade openness on FDI in Vietnam, in the period from 2005 to 2019. The research data are time-series data, with quarterly frequency, from 2005:Q4 to 2019:Q3. The FDI data were collected by International Financial Statistics. The data of trade openness were calculated based on Vietnam's export, import, and GDP data collected by the General Statistics Office of Vietnam. The estimated result shows that the trade openness has a positive effect on FDI. The current FDI is heavily influenced by FDI in the past with an average explanation of 74%. The main findings indicate that trade openness has a positive effect on FDI inflows into Vietnam. The findings also show that FDI in Vietnam is significantly affected by the shocks of the FDI itself in the past. The findings of the study suggest the Vietnamese Government improves the quality of trade openness and FDI, continues and maintains economic relations with other countries to increase trade openness.

액셀러레이터는 스타트업에게 창업지원시설, 자금, 사업화, 판로확보 등의 다양한 애로사항을 종합적으로 지원하는 민간투자기관이다. 액셀러레이터가 새로운 창업지원 모델로 투자자 역할 외에 집중적인 멘토링을 통해 스타트업의 사업능력 향상에 많은 기여를 하고 있다. 본 연구는 기존 선행연구들이 투자자관점의 투자결정요인에 치중한다는 점을 고려하여, 액셀러레이터 투자자 창업자 간의 스타트업 투자결정 요인에 대한 상대적 중용도를 AHP방법을 통해 비교 분석하였다. 그 결과, 액셀러레이터 투자자는 스타트업의 "경영자 특성"을 스타트업 창업자는 스타트업의 "시장 특성"을 상대적으로 가장 중요하게 평가하였다. 이러한 결과는 투자자 관점에서 스타트업의 성공이 창업자의 역량에 좌우한다는 경험적 판단에 기인한 것이며, 창업자는 투자자가 투자회수기간을 고려하여 스타트업의 시장성을 중요하게 평가한 것으로 보인다. 이러한 결과는 엔젤투자자, 벤처캐피탈의 투자결정요인에 대한 기존 연구결과와 유사하였다. 본 논문은 액셀러레이터가 성장가능성 높은 스타트업을 발굴하고 인큐베이팅과 투자에 더 많은 성과를 내기 위한 투자결정모형의 고도화에 기여할 수 있을 것이다.

Korea has suffered from unemployment of workers discharged from the companies and graduates, and matriarchs since 1997's IMF. Since then Korea has fallen into economic depression, therefore the graduates have not employed for several years and lots of workers have been discharged from their positions. SOHO(Small Office Home Office) is able to be considered as the alternative employing measure of the unemployers. SOHO foundation makes a great contribution to job creation and the social welfare throughout the country. Since its foundation needs small-scale facilities and investment, the discharged and unemployed can found SOHO easily and will do good business. Korea government should practice policies in order to promote SOHO foundation as follows. First, Korean government should enlarge various support measures for SOHO foundation, namely offering of useful information and promoting of SOHO foundation, etc. Second, she should carry out the SOHO foundation education for juveniles. In order to do this project, colleges and universities adopt the SOHO foundation lesson in the education course. Third, government should enlarge various government subsidies of SOHO foundation for the benefit of the discharged and unemployed.
