본 연구는 빅데이터를 활용하여 투자 및 육성지원이 지역내총생산에 미치는 영향력을 다중회귀분석을 이용하여 분석하였다. 지역내총생산(GRDP)은 각 지역의 생산규모·지출수준·소득수준·산업구조 등을 집약적으로 내포하고 있는 지수로써, 지역경제 분석 및 국가의 정책수립에 활용하는 중요한 자료이다. 국가의 주요 국정과제를 올바르게 수행하기 위해서는 지역경제를 정확히 파악하는 것이 선행되어야 하는데, 이로 인해 최근 지역내총생산에 대한 관심이 급격히 증가하고 있다. 특히 해외투자는 투자유치국의 경제에 미치는 영향력이 상당하여, 이에 대한 많은 실증분석이 이루어지고 있다. 본 연구에서는 해외투자 및 국내육성지원이 지역내총생산에 미치는 영향력을 상관분석과 다중회귀분석을 실시하였으며, 그 결과 전체적으로 투자와 지원이 지역내총생산에 긍정적인 영향을 미친다는 결론을 도출하였다.

The present study has quantitatively assessed the regional production, income and employment impact resulting from the construction and operation of nuclear power plant (NPP) upon the domestic local areas by applying the regional input-output analysis model to the case of Wolsong unit-l site. The conclusions regarding the most likely regional economic impacts upon the wolsong site are summarized as follows: 1. The income multipliers are calculated to be 1.563 for the construction phase and 1.500 for the operation phase. These values are relatively high compared with those of other conventional facilities. 2. The level of total employee's wage induced employment associated with the construction phase has been estimated to be 37,000 while that with the operational phase in 1990 to be 5,610. 3. With relation to the aspect of resident welfare it is found that the industrial sector associated with electricity, gas and water supply have remarkably improved with the construction of the NPP. 4. The NPP siting has induced substantial changes in interindustry (input-output) structures of the Wolsong unit-l site which is one of the rural areas where all the domestic NPPs are sited. Such changes are attributed to the industrial recomposition of the region. 5. With the application of other regional economic analysis models and the use of more sufficient regional data, other detailed studies on the economic impact analysis of domestic NPP-related facility sitings are suggested to be carried out further since the influence of NPP sitings is significant to the national economic impact as well as the regional economic impact.

A system for fine-resolution long-range weather forecast is introduced in this study. The system is basically consisted of a global-scale coupled general circulation model (CGCM) and Weather Research and Forecast (WRF) regional model. The system makes use of a data assimilation method in order to reduce the initial shock or drift that occurs at the beginning of coupling due to imbalance between model dynamics and observed initial condition. The long-range predictions are produced in the system based on a non-linear ensemble method. At the same time, the model bias are eliminated by estimating the difference between hindcast model climate and observation. In this research, the predictability of the forecast system is studied, and it is illustrated that the system can be effectively used for the high resolution long-term weather prediction. Also, using the system, fine-resolution climatological data has been produced with high degree of accuracy. It is proved that the production of agrometeorological variables that are not intensively observed are also possible.

본 연구는 2010~18년 동안의 우리나라 16개 광역시·도(세종시 제외)별 자료와 패널 벡터자기회귀(Panel VAR) 모형을 이용하여 에너지 소비량, 신재생에너지 생산량, 실질 지역 내 총생산, 온실가스 배출량 간의 관계를 실증분석하였다. 분석 결과, 에너지 소비 증가가 신재생에너지 생산 및 지역 내 총생산을 증가시키는 효과는 제한적인 가운데 온실가스 배출을 증가시키는 것으로 나타났다. 신재생에너지 생산 증가는 지역 내 총생산을 증가시킬 수 있는 반면 에너지 소비 및 온실가스 배출량 저감에는 대체로 유의미한 영향을 미치지 않았다. 이러한 분석 결과는 국가 온실가스 저감과 지역 경제성장 목표 달성을 위해서는 에너지 소비 감소와 함께 신재생에너지 보급 확대가 중요함을 보여준다.

본 연구는 지식창출활동에 초점을 두고 투입요소인 연구개발비와 연구인력, 그리고 지식창출활동을 통해 최종 성과로 나타나는 지역경제성장간의 동태적 인과관계를 분석하는데 목적을 두었다. 1998-2008년 동안 16개 광역시 도를 포함하는 Panel-VAR모형을 사용하였으며, 특허 생산성이 높은 지역과 특허 생산성이 낮은 지역을 구분하여 네 변수간의 인과관계를 추정하였다. 그랜저 인과분석을 수행한 결과 연구개발비와 연구인력은 특허출원에, 그리고 특허출원은 GRDP에 유의미한 인과관계를 갖는 것으로 나타났다. 또한 이러한 인과관계는 일방향이 아니라 양방향으로의 인과관계가 나타나고 있어 순환적 피드백 인과구조를 갖고 있다고 풀이할 수 있다. 이러한 경향은 특허 생산성이 높은 지역에서 더욱 뚜렷하게 나타났으며 특허 생산성이 낮은 지역에서는 연구개발비와 GRDP 간에 일방향의 인과관계가 나타났다. 이와 같이 두 지역 간에 다소 다른 인과관계 패턴이 나타난다는 점은 두 지역의 혁신역량을 향상시키려는 지역혁신정책도 차별화되어야 할것임을 시사해준다. 앞으로 지역경쟁력을 제고시키려는 지역정책의 초점도 특허 생산성을 높일 수 있도록 유도하며, 연구 개발결과가 단지 지식창출활동에 그치지 않고 창출된 지식이 실질적인 경제성장을 가져올 수 있도록 지역 내 혁신 인프라를 구축하는데 두어야 할 것이다.

As an exit to solve the economic depression of the development countries in the early twentieth century, the 'old international division of labor' developed. The economic crisis(i.e., under-consumption crisis) was due to the absence of the mode of regulation compatible with the extensive regime of accumulation(i.e., "Fordist" regime). The crisis was solved by the state intervention through the creation on institutions in order to increase the level of consumption. Until the late 1960s when "high Fordism" reached(i.e., a harmonious relation between the monopoly mode of regulation and the intensive accumulation of capital), the developed core countries enjoyed a remarkable economic growth. The external market was not a necessity for the economic growth because there were increases in labor productivity and proportional increases in real wages and thus increases in consumption level. In the 1970s, however, the core faced with economic crisis again. Due to the breakdown of the postwar "Fordist" regime of capital accumulation and the post 1973 world depression, the core needed the Third World as a solution for their internal and international economic crisis. Thus the 'new international division of labor'(NIDL) arose. The "Fordist" method of production(i.e., the divisions of production process) led to the territorial division of labor and to the detailed division of labor. The aim of the NIDL is to exploit reserve armies of labor on a world scale and thus to reduce production costs. According to the NIDL model, the Third World countries have been developing by the core countries' investment on mainly labor-intensive industries and thus have been playing an important role in the global economy. And the NIDL theorists argue that multinational corporations have increasingly invested in the Third World nations and contributed to the economic growth in those regions. Tables presented in the paper show that the global trend since the 1970s does not follow the argument exactly as the NIDL theorists predicted. On the contrary, the core countries focus on developing technology, adopting the automation of production process, and trading within the core countries rather than on investing in the periopheral countries. The continuing investment of multinational corporations into the periphery is not because of cheap labor force but because of the market potentials in the regions. Majority of corporations of the core tries to reduce production costs by investing in technological development more intensively and also by changing regional strategies (i.E., investment from metropolitan areas to medium - or small - size cities, focusing on agglomeration economy, boosting regional diversification, etc.) within their own countries. The main purpose of the paper is to review and to criticize the NIDL theory based on some empirical data.IDL theory based on some empirical data.

본 연구는 패널 공적분 검정 그리고 비교적 최근에 개발된 패널 단위근 검정을 이용하여 지역 주택가격과 지역총생산 간의 장기관계를 분석하였다. 횡단면 의존성(cross-section dependence)이 확인된 경우, 이를 고려한 Pesaran의 CIPS 패널 단위근 검정을 이용하였다. 기존 패널 단위근 검정의 결과와 다르게 CIPS 검정은 변수들이 불안정성을 갖는 것으로 나타났다. 또한 패널 벡터오차수정모형(VECM)을 이용하여 변수들 간의 인과관계를 확인하였으며, 고정효과모형(Fixed effect)과 패널 자기회귀시차(ARDL)모형을 이용하여 계수들의 장기관계를 구체적으로 추정하였다. 먼저 변수들 간에 공적분관계가 형성되며 장 단기 인과관계가 성립하는 것으로 나타났다. 또한 VECM 모형의 오차수정항은 통계적으로 유의한 것으로 나타나 변수들 간의 장기 공적분 관계를 뒷받침하고 있다. 모형의 추정 결과, 장기적으로 주택가격의 상승은 지역총생산을 증가시키며 반대의 관계도 성립함을 알 수 있다. 이 결과에 의해 우리나라 지역 주택시장에서 부의 효과(wealth effect)가 존재하고 있는 것으로 나타났다. 이러한 결과들과 함께 오차수정항으로부터, 주택 가격과 경제 변수들은 단기적으로는 일시적인 균형상태로부터 이탈될 수 있지만, 장기적으로는 이들 변수는 균형관계에 있다는 것을 의미한다.

The purpose of this paper is to evaluate the accuracy of input coefficients which are usually estimated by various non-survey methods. The resulting analysis showed that there were considerable differences employed. One of the interesting findings was that the simple LQ method was shown to be better then the other non-survey methods with respect to the degree of accuracy. And from a sensitivity analysis which was to show the effect of changes in input coefficients on the level of production by industry, an increase of 10% in the value of input coefficient (machinary and equipment setor) resulted up to 500billion Won in GRP for the case region. Therfore one of the implications which we can derive from the resulting analysis is that it necessary to pay attention to the key coefficients first to save out time and money, while retaining a certain level of accuracy. One thing to be noted, however, is that the key coefficients but the total effects which are calculated through the Leontief inverse matrices. Therfore to enhance the accuracty of input coefficients estimated by nonsurvey methods it is required to handle the relevant setoral data more carefully or to employ semi-survey method in part.

This gas analysis data come from the hydrogen which is produced by proton exchange membrane. Main impurities of hydrogen are methane, oxygen, nitrogen, carbon monoxide, and carbon dioxide. The concentration of impurities is ranged between 0.0191 to $315{\mu}mol/mol$ for each impurity. Methane contamination is believed from the electrode reaction between carbon doped electrode and produced hydrogen. Nitrogen contamination should take place the sampling process error, not from PEM hydrogen Production system.

The purpose of this study was to assume suitable cultivation areas by items and expectably suitable cultivation areas through coefficient of specialization and spatial concentration analysis, and suggested regional specialized items discovered by this research and regional specialized business management plans & development directions. This study has monitored changing aspects of spatial distribution of suitable cultivation areas in stockbreeding items from 2000 to 2010 by applying methods of location quotient(LQ), a multiple model, and etc, and predicted changing aspects of suitable cultivation areas from 2015 to 2020. As the result of analysis, I found that there were specialized items which were spatially concentrated and that there were hot-spots which were focused on some areas by items. Additionally, there were suitable cultivation areas which remained stable or changed by them. To discover specialized items and to develop businesses, I have suggested that it is necessary to ensure business project's feasibility including the present conditions, circumstances & potential of specialized items, and etc., and to secure business competitiveness including technology exchange, production cost curtailment, business management based on consumer's needs and building systematic data about achievement and etc.
