This study examines the direct and indirect impact on air pollution by 1) the regional manufacturing industry’s production output and 2) industrial electric power use. We also analyze the effects of the environmental regulation on the air pollution emissions and productivity of manufacturing industries in “5+2” specific regions in Korea using panel approaches with period SUR. The results show that manufacturing industries outputs affect to raise the air pollution emissions as well as energy consumption. Especially, refined fuel manufacturing outputs affect the air pollution emissions seriously. However, the regulation effects are not significant to decrease emissions for increasing the productivity of manufacturing industries. It means that the Korea is needed to invest the environmental technologic R&D based on the regional differences..

인터넷의 확산과 정보통신 기술의 발전으로 무역업무의 효율화를 위해 도입되었던 VAN/EDI와 무역 자동화 중심의 전자무역 환경이 점차ebXML프레임워크 기반의 글로벌 전자무역 환경으로 바뀌어 가고 있다. 본 논문은 글로벌 전자무역 환경에서의 보안요소와 전자무역의 안전성과 신뢰성을 확보하기 위한 보안 표준기술로 SSL과 ebXML을 제시하였다. 이와 더불어, 거래 당사자에 대한 강력한 인증과 전자거래에 법적인 효력을 부여할 수 있는 전자서명 상호인정 기반의 전자무역 실현을 위한 3단계 방법론을 제안하였다. 실현 1단계로, 전자서명 적용을 위한 전자무역 비즈니스 프로세스 표준화 및 전자서명 상호인정 협정 협의체를 구성하고, 2단계에서는 전자서명 기반의 전자무역 시스템 설계 및 전자서명 상호인정 기술을 구현한다. 마지막, 3단계에서는 국가간 전자서명 상호인정 협정 체결하고 전자무역 서비스의 운영한다. 또한, 전자무역 프로세스에서 전자서명이 적용 가능한 전자무역 모델을 제시하였다. With the expansion of internet usage and the advanced technology for information and communication, the international e-Trade environment gradually migrates from the VAN/EDI to the global Internet-based e-Trade on an ebXML framework. In an effort to provide a Internet-based e-Trade environment with a security and trust, this paper analyzes security components and proposed the SSL and ebXML security technologies in order to assure of the trust and security over Internet-based e-Trade. In addition, this paper presents 3-phase methodology to realize the secure and trustworthy Internet-based e-Trade. In summary, as the first phase, the e-Trade business processes are re-engineered and the digital signature council for mutual recognition is organized. And as the second phase. the Internet-based e-Trade system and the concerned digital signature technology are implemented. Finally as the third phase, the PKI mutual recognition agreement is signed by parties concerned and then the Internet-based e-trade business is started. Furthermore, this paper presents the promising Internet-based e-Trade models where the digital signature can be applied.

물가, 성장, 실업간 상호연관성 연구

This paper analyses the co-relationship among the inflation, growth, and unemployment, and focuses whether the inflation takes a leading indicator or not for the other variables in this model. The results of impulse response function say that the inflation has a little effect to growth and unemployment, however, unemployment has a deep effect to growth. In addition, the results of variance decomposition say that the inflation variance has a little effect to other variables such that we can not support the traditional Phillps curve hypothesis in the view of Keynes. That is, in Korea, there exists a natural unemployment which dost not affected by growth and inflation. Therefore, government needs to establish the fiscal and labor policy so as to reduce the size of unemployment because unemployment does affect to growth seriously.

패널분석을 이용한 6대 권역별 대기오염물질에 대한 환경규제와 경제성장 간의 상호관계분석: EKC(환경쿠즈네츠곡선)가설을 중심으로

박추환 ( Chu Hwan Park ) 한국환경연구원 2013 환경정책연구 Vol.12 No.2

We analyzed the correlation among the GHG (Greenhouse Gas) emission, energy consumption and economic growth for the 6 specific regions in Korea by using Panel approaches with the test of the EKC hypothesis. We also analyzed the effects of environmental regulation on GHG and economic growth. The results show that by testing of the EKC (Environmental Kuznets Curve) hypothesis model, the effects of the environmental regulation and the structure of industries on GHC emission have a significant result on the regional analysis for SOx. For the NOx and TSP, only TK region passed the turning point of the EKC among the 6 specific regions. And, for the Co, the Central, Honam and the PUKN region passed the turning point of the EKC. This is because GHG emissions by the environment regulation had a weak path effect and also regional industry structures had a weak relation with regional GHG emissions.

In this paper, we analysed the determinants of the productivity divergence in service industries from 1990 to 2009 with 16 provinces and metro-cities by using panel analysis. So it is necessary to compare with regional product (GRDP) and income in order to identify regional product incidence, but the variables are not exist to explain regional income formally. Therefore, private consumption and tax, as the candidate indicators of the regional income, are used to analyze the regional disparities. The results show that the size of regional industrial causes significant effect to the value-added per capita and regional income disparities. This is because regional disparities of the capital in steady state are different by applying conditional convergence. Because of the productivity divergence in service industries, regional income disparities have widened. Hence the government has to revise the balanced regional development policy to develop regional service industries rather than manufacturing industries for balanced regional development. Also, it requires more study regarding income disparities and productivity.

권역별 금융 구조 및 역할변화와 1인당 부가가치 간 영향분석

This paper investigates the effects of finance on regional economic growth since the Asian financial crisis of 1997 through a panel analysis. This crisis has reduced the role of non-bank depository institutions through the restructuring of regional enterprises and financial institutions and thus had a negative effect on small regional manufacturers. As a result, on the increase of regional manufacturing value added per capita, effect of non-bank depository institution variables proved to be much less than those of depository money bank, and it was verified that, especially after 2001 when IMF restructuring ended, the role of regional retail financial institution has been remarkably reduced. Looking at the result of empirical analysis after 2000 to identify the effect of reduced role for regional retail financial institutions on enterprises by size, variables of depository money bank appeared to be significant for large and small enterprises while variables of non-bank depository institutions relatively has had effect on small enterprises. As to manufacturing technological progress, on small and med-sized enterprises, depository money bank turned out to have a larger effect. That is, in terms of profitability, non-bank depository institution has contributed but depository money bank has a larger effect on technological progress.

In this paper, we analysed the absolute and conditional convergency hypothesis and the determinants of productivity in manufacturing industries from 2000 to 2009 with 16 provinces and metro-cities by using panel analysis. In terms of convergency hypothesis test, the results show that both of the convergency hypothesis, the absolute vs. conditional hypothesis, reject the null hypothesis(H0) implying the labor productivity of the 16 province and metro-cities converged to the steady state equilibrium. Also, the speed of the absolute and conditional convergency for the 16 province and metro-cities are average 4.4% and 0.73% respectively. In addition, the results of the determinants of the labor productivity in manufacturing industry show that human capital and manufacturing location coefficient affect to the value- added per capita significantly, but government expenditure per capita doesn`t affect to the value- added per capita. As for the total factor productivity, government expenditure per capita and fixed capital per capita are important factors, but research and development doesn`t. Hence the government has to revise the balanced regional development policy to develop regional manufacturing industries for the vulnerable regions. Also, it requires more study regarding income disparities and productivity.
