With the advent of new order of international competition, the technology Policy of Korea has been changed from vertical one which focuses on specific technologies or selective industries to a horizontal one which supports R&D activities on a neutral basis. TIP(Technology Infrastructure Policy) is WTO free in the sense that it is Indirect method of supporting technology development and properly defined as a part of government role by OECD. Technology infrastructure is embodied in human capital, and includes also elements of physical capital and knowledge. Hence it is more differentiated than, and distinguished from conventional infrastructure. It implies a need for carefully designed strategy with the recognition of those differences. As a fundamental element of innovation and technological development, technology infrastructure should become the main focus of industrial technology Policy.

This paper investigates the relationships between exports, firm size, and firm dynamics. It is based on a longitudinal data covering listed firms in the Korean manufacturing industry. We found the stylized fact that the probability that a firm is exporter increases with firm size. A regression model for the determinant of export/sales ratio including dynamic adjustment process is tested on a cross-section sample for the year 2001. Empirical findings suggest that there is a positive and inversely U-shaped relationship between firm size and export/sales ratio, just for basic material and capital good industry. Except for firm size, the hypotheses concerning human capital intensity, physical capital intensity, R&D intensity, and patent are rejected. Using Granger causality test, we found that the rate of growth of total sales influences the change of the export/sales ratio with time lag for medium-sized firms. Finally, some policy implications are presented.

현행원가회계시스템의 핵심개념인 경영이익개념은 현행영업이익과 보유이득으로 구성된다. 보유이득의 성격에 대해서는 자본수정설과 이익설의 두가지 견해가 있다. 전자의근거는 조업능력유지개념인 반면, 후자의 근거는 재무자본유지 개념이다. 현행원가회계 주장자들은 그것이 전통회계보다 더욱 유용한 정보를 제공한다고 확신하고 있다. 재무자본지지자들은 현행원가정보가 경영자들의 과거의사결정의 평가에 필요하고, 따라서 그들의 의사결정능력을 개선할 수 있다고 한다. 실물자본지지자들은 기업을 지속적으로 경영하기 위하여 기업의 조업능력이 유지되었는지를 알아야 할 필요성을 강조한다. 역사적원가회계 지지자들은 현행원가회계가 자산을 판매하기 전에 자산가치의 증가를 인식함으로써 전통적인 수익인식원칙을 위반하고, 회계과정에 지나치게 주관성이 개입되어 있다고 믿는다.

본 연구는 우리나라 광역시와 도를 중심으로 1995-2017년의 지역별 패널통계를 활용하여 노동력 고령화가 인적자본 취업비중과 1인당 지역총생산에 미치는 영향을 분석하였다. 지역별 고정효과를 반영한 2단계 최소자승 패널 회귀 분석 결과에서 노동력 고령화는 광역시의 인적자본 취업비중과 1인당 지역총생산에는 영향이 없는 반면, 도의 인적자본 취업비중과 1인당 지역총생산은 유의한 수준에서 감소시키는 것으로 나타났다. 또한 서비스 사업체 비중은 광역시의 인적자본 취업비중에 긍정적 영향을 미치지만 도에서는 그 효과가 유의하지 않게 나타났으며, 광역시에서는 인적자본 취업비중이 1인당 지역총생산 증가에 유의하게 기여하고 있지만 도의 경우는 물리적 자본이 1인당 지역총생산 증가에 유의하게 기여하고 있는 것으로 나타났다. 이와 같은 광역시와 도에 따른 다른 분석결과는 노동력 고령화에 대응하는 인적자본과 1인당 지역총생산 증가를 위한 광역시와 도의 최적화된 정책은 지역에 따라 차별화시켜야 함을 시사한다.

Petroleum is the most used energy source in Korea with a usage rate of 39.5% among the available 1st energy source. The price of liquid petroleum products in Korea includes a lot of tax such as transportation·environment·energy tax. Thus, illegal production and distribution of liquid petroleum is widespread because of its huge price difference, including its tax-free nature, from that of the normal product. Generally, illegal petroleum product is produced by illegally mixing liquid petroleum with other similar petroleum alternatives. In such case, it is easy to distinguish whether the product is illegal by analyzing its physical properties and typical components. However, if one the components of original petroleum product is added to illegal petroleum, distinguishing between the two petroleum products will be difficult. In this research, we inspect illegally produced gasoline, which is mixed with methyl tertiary butyl ether (MTBE) as an octane booster. This illegal gasoline shows a high octane number and oxygen content. Further, we analyze the different types of green dyes used in illegal gasoline through high performance liquid chromatography (HPLC). We conduct component analyses on the simulated sample obtained from premium gasoline and MTBE. Finally, the illegal gasoline is defined as premium gasoline with 10% MTBE. The findings of this study suggest that illegal petroleum can be identified through an analytic method of components and simulated samples.

In Korean context, the innovative cities imply new towns or urban clusters in the Non Capital Regions, all of which would accommodate the relocated Capital based public organizations. The central government-initiated innovative cities have provoked pros and cons towards their effectiveness and efficacy for the balanced territorial development. From a broader prospective, this paper firstly examines the current status quo of the innovative cities. Based on their master plans, it analyzes physical and non physical factors which would exert significant impact on the innovative cities. Secondly, it pays attention to how key factors strengthen or weaken their behavioral patterns in terms of dynamic location and implementation policies of the innovative cities. Using System dynamics approaches, it sets up couples of scenarios, categorizing between supporting and opposing arguments towards the innovative cities. Lastly, after divulging systematic structure of the innovative cities, it proposes a series of practical alternatives which would contribute to minimizing unexpected side effects or unwanted social cost in the long run. In order to guarantee reinforcing structure of the innovative cities, the paper suggests that QOL (quality of life) variables, which would require continuous investment in the social infrastructure, are pivotal in achieving original goals of the innovative cities. Otherwise, the innovative cities would not be innovative per se. In the worst case, they might be degraded into the unpopular ghost towns.

The estimate on volatility of stock price is related with optimum of portfolio and Important for allocation of capital asset. If the volatility of stock price is varied according to macroeconomic variables on monetary policy and industrial production, it will assist capital asset to allocate. This paper is related with stock market volatilities on macroeconomic variables in U.S. and Europe, Korea. And, it Is pertain to vary in time of this variables. Thus, this paper is related with volatilities of monetary and physical macroeconomic variables on basis of statistics. And, it is ranged front capital investment to portfolio allocation. Also, this paper takes out of sample forecast and study more after this. In case Germany, France, Italy and the Netherlands, the relative importance of monetary policy and Industrial production Is different from these countries. In case Italy and the Netherlands, monetary policy is primary factor at stabilizing for volatility of stock price. In case Korea, increasing monetary policy and industrial production is positively affected stock market. It is that the positive effect of stock price is caused by mollifying monetary policy and economic growth. Specially, this conclusion is similar to US. In Korea, gradual increase in monetary and industrial production is necessary to stability of stock market. It is different to previous results on basis of increasing stock price of money in long period.
