This study analyzed the determinants of carbon dioxide emissions through the expanded STIRPAT model using panel data from 16 metropolitan cities and provinces in Korea from 2000 to 2019. After testing cross-sectional dependence and coefficient heterogeneity of panel data, we performed analysis using MG, CCEMG, and AMG estimation methods reflected these characteristics. The results of analysis using the AMG estimation method are as follows. The coefficients of income, population, and energy intensity were statistically significant with a positive sign, but urbanization was statistically insignificant. Reduction of carbon dioxide emissions in Korea can be achieved through an increase in energy efficiency and sustainable economic growth. It is necessary to establish a policy that can contribute to sustainable economic growth by inducing productivity improvement through technology innovation reducing carbon dioxide emissions in the long-term as well as building a low-carbon society through active development of carbon dioxide reduction technology.

In this paper, we have tried to evaluate the economic value of technological information. Toward this aim, we have adopted the newly emerging method of contingent valuation which capitalizes on the direct survey through users. The estimated result indicates the strong support for the public activities to provide and diffuse technological information. We also tried to shed light on the implications of the research finding for government technology policy.

웹2.0이라는 개념과 트랜드는, 개방성, 사용자 참여, 집단 지성, 인간중심의 IT 서비스 등을 키워드로 하는, 플랫폼 기반 비즈니스 모델을 통칭한다. 전세계적 블로그 열풍이나, Googlization으로 불리기도하는 주요 웹포탈의 성장은 이러한 현상을 뒷받침하는 증거이며, 미래 인터넷 시장을 개척하는 엔진으로 자리잡고 있다. 그런데 웹2.0을 기술적으로(descriptive) 소개하거나 관련된 요소기술에 대한 문헌은 많음에도 불구하고, 이러한 현상을 경영/경제학적 시각에서 체계적으로 분석한 연구는 의외로 많지 않다. 본 논문에서는 기존의 웹(웹1.0)과 웹2.0 서비스 모형을 경영 경제학적 관점에서 구조화하고, 이들 서비스 모형을 Stakelberg 게임의 관점에서 분석한다. 특히 본 연구에서는 웹2.0의 다양한 국면 중에서 프로슈밍(prosuming)에 초점을 맞춘다. 분석 결과, 웹2.0에서 사용자 후생이 웹1.0에 비해 크게 증가한다는 것을 확인할 수 있었다. 또한 사용자 스스로 맞춤화된 정보를 창출하는 노력과 한계편익간의 비율을 나타내는 ${\delta}_c$('고객화 요소'로 부름) 분포의 범위(파라미터 ${\delta}$)가 사회후생에 중요한 역할을 함을 발견하였다. 이는 고객화 요구의 다양성이 커짐에 따라 사용자 후생을 비롯한 사회후생도 증진됨을 의미한다.

As the research and development(R&D) has become a necessary motive in social development, the importance on the evaluation of the technical information service is also emphasized. Among others, the economical evaluation and the productivity of the technical information service are very complex and complicated as of the information value. Also the technical information service is influenced by its infrastructure. Therefore, the economical evaluation on the productivity of the technical information service requires a more systematic and complex approaches simply to be more objective and rationalized.

The purpose of this study is to analyze the ripple effect of the Chinese education industry on the national economy by using the industry-related table of 2017 by the China Statistical Office to use it as policy data for revitalization of the Chinese education industry in the future. To achieve this purpose, 149 industries in the basic classification of the industry-related table were classified into 32 industries. Based on these classifications, by analyzing the production induction coefficient, sensitivity coefficient, influence coefficient, yield inducement coefficient, production tax induction coefficient, and labor induction coefficient, etc. The purpose of this study is to understand the relationship between different industries and to find out the economic impact of the Chinese education industry. The analysis results show that in 2017, the total production induction coefficient of China's education industry was 1.7188, the row total was 1.0626, the sensitivity coefficient was 0.01211, the influence coefficient was 0.01958, the income induction coefficient was 0.6667, the production tax induction coefficient was 0.035, and the final demand was 1 billion yuan. When this occurs, the labor induction coefficient shows a total of 31,254 persons (indirect 15,541 persons, direct 15,713 persons). Based on the analysis results, this study suggested the implications that government support, technology introduction and application of new operating models, policy regulations, and efficient supervision of the system and president are required for further development of the Chinese education industry.

Libraries have been made effect to satisfy customer by reflecting information need of customer on libraries. They have considered introducing the data mining techniques to analyze complicated and massive data of libraries and the Customer Relationship Management(CRM) to produce suitable services to each customer segmentation. The purpose of this study is to apply the CRM and data mining techniques to a library, ultimately intends to suggest rules for the collection management and the customer management.

본 연구에서는 리카도가 자신의 "정치경제학(政治經濟學)과 조세(租稅)의 원리(原理)"(이하에서는"원리(原理)"라고 하겠음) 3판에 새로이 도입한 "기계(機械)"의 내용을 중심으로 기술진보(技術進步)가 고용(雇傭)에 미치는 영향(影響)에 대해 살펴보고자 하였다. 리카도는 당시 대부분의 주류 경제학자들과 마찬가지로 과학의 발전과 기술진보로 인한 새로운 기계(機械)의 도입은 근로자, 자본가 및 지주를 포함하는 모든 계급(階級)에게 유리한 결과를 가져오리라 생각하였다. 그러다가 그는 "원리(原理)" 3판을 작성하면서 이러한 자신의 견해가 잘못된 것임을 시인하고, 새로운 기계(機械)의 도입이 근로자(勤勞者)에게는 불리한 결과를 가져올 수 있음을 분석적인 방법으로 보여주었다. 그러나 이러한 리카도의 시도는 당시 및 후대의 경제학자들에 의해서도 지적되었듯이 부분적으로 논리적인 오류(誤謬)를 범하였다. 리카도의 논리적 오류를 수정하면서도 그의 문제의지(問題意識)을 부각시키기 위해 본 연구에서는 힉스에 의해 도입된 신(新)오스트리안(Neo-Austrian) 자본개념(資本槪念)과 이에 입각한 기술진보(技術進步)의 형태분류를 리카도의 분석틀에 적용시켰다. 그 결과 일정한 형태의 기술진보하에서는 수익성이 높은 기계(機械)가 도입될지라도 과도기적으로 고용(雇傭) 및 총생산물(總生産物)에 불리한 효과를 나타낼 수 있음을 보여주게 되었다. 그리고 과도기적으로 기계(機械)의 도입에 따른 기술적(技術的) 실업(失業)이 발생할 경우 그 기간에 영향(影響)을 주는 요인(要因)에 대해서도 살펴보고자 했다.

In this study we analyze the performance of overseas subsidiaries of Korean multinationals with localization in sales, purchase, and employment. We use the data of 2,116 overseas subsidiaries in 61 countries between 2008 and 2011 provided by The Export-Inport Bank of Korea. As a result, analysis shows that the effect of localization on the performance is quite different by sectors and countries which the subsidiaries have entered. In the manufacturing sector, increase of local sales has positive effect only in China, while local purchase improves the performance of the subsidiaries in developing counties excluding China. However, the subsidiaries which had made a foray to service sector in advanced countries aquired better performance with localization of sales, purchase, and employment, whereas those in China had no merit except localization of purchase.

Based on the theory of information ecology, this paper conducts a quantitative analysis on the research literature of e-commerce ecosystem in China, and clarifies the research hotspots and development trends, so as to provide reference for subsequent studies. With the key words related literatures collected by CNKI as the data source, and the software CiteSpaceIV is used to draw a visual knowledge map, the distribution of e-commerce ecosystem research papers in China is statistically analyzed by econometric analysis method, and literature research is summarized and evaluated. The research results show that previous studies mainly focus on the concept of e-commerce ecosystem, and there are relatively few research results on the construction and evolution mechanism of e-commerce ecosystem, so the depth and breadth of research should be expanded. Applying the concept of e-commerce ecosystem to solve the problems in cross-border e-commerce will be the future research trend.
