인간의 생태계를 근본적으로 위협하고 있는 기후변화와 같은 환경오염 문제는 글로벌 경쟁시대의 기업 경영에 있어 강력한 제재요인 중 하나로 관심이 집중되고 있다. 국내에서도 이러한 환경문제가 중요 이슈로 부각되고 있는데, 특히 인류생존에 필수적인 자연환경을 기반으로 사업을 영위하는 농업분야는 더욱 깊은 연관성을 갖는다. 정부는 이러한 농업분야에 대하여 도시와 농촌 간 소득 불균형이나 농촌인구 노령화 등의 문제를 해결하고 미래 성장산업으로 발전시키고자 6차산업화 인증 제도를 시행 중에 있으며 앞으로의 성장이 기대된다. 또한 최근 기업의 환경을 포함하는 사회적 책임활동에 대한 관심이 높아지고 능동적으로 참여하려는 소비자의 특성 변화에 따라 6차산업화 인증을 받은 기업들도 성장하기 위해서는 기업 활동의 근간이 되는 소비자 니즈에 더욱 집중할 필요성이 제기되므로 기업의 새로운 성장 방안으로써 고객과 환경에 집중하고 사회적 가치를 창출해 나가야 할 것으로 추측된다. 이에 본 연구에서는 6차산업화 인증을 받은 기업을 대상으로 고객지향성과 경영성과 간 관계에서 환경지향성이 조절효과를 가지는 지를 밝히고자 하였으며, 연구 결과 고객지향성은 경영성과에 정(+)의 영향을 미치며, 이러한 관계 속에서 환경지향성은 정(+)의 조절효과를 가진다는 것을 실증하였다. 즉, 6차산업화 인증기업이 경영성과를 제고시키기 위해서는 소비자의 변화와 기업이 수행해야 할 사회적 책임을 명확히 인식하여, 소비자 니즈기반의 환경보존과 같은 사회적 가치를 창출하고 공유하려는 친환경 지향적인 새로운 혁신전략을 수립하고 실행해 나가야 할 것이며 이를 통해 지속적인 성장을 견인할 수 있을 것이다.

In this paper, we estimate whether changes in the economic environment a firm operates in affects technical efficiency. Since efficiency gains can manifest themselves in a variety of ways, we estimate for efficiency gains on annual generating plants input demand for expenses and fuel use. We find that generating plants reduced their workers and costs respectively by 6.8% in 1999 and 37.9% in 2001. However, they didn't show any systematic caloric consumption changes facing various economic environmental shocks. These results suggest that restructuring brought efficiency gains by replacing regulated monopoly with a more competitive firms in the context of the Korean electricity market.

This study analyzes the influence of the construction of a high-speed railroad on territorial organization in France. After development of a new transportation network, the French territorial organization has been largely modified. Many economic urban areas are modified by their position in the territorial hierarchy according to their condition of connection with the TGV network. At first, spatial convergence is the most important effect of the TGV network construction. Second, the development of a transportation network concentrated in the Paris area has influence as an intensified factor on metropolitan areas and as a weakening factor on middle- and small-sized cities. Thus, this system has risk in increasing territorial imbalance in France. Third, to implant an economic activity zone around new TGV stations, a new town or a new economic center starts to develop. This is going to grow into a second core outside of the old city center so that regional spatial organization is transformed from a mono-polarized(mono-centric) organization to a multi-polarized(polycentric) one. Lastly, the integration of the EU railroad system enhances the concentration of economic activity in European metropolitan areas as each metropolitan area tries to develop more competitive space for its rising position in the global urban hierarchical system.

The development of information and communication technology (ICT) provides many opportunities for businesses to increase productivity, to have better relationships with customers and suppliers, and to develop new products more efficiently and effectively. However, recently, there have been claims that ICT development in a country would increase income inequality of the country. In this debate, we examine the impact of ICT development on the income inequality at the country level. Data of 28 OECD countries were used for our study. According to results of the analysis, a country with a higher level of ICT development is likely to have a lower the level of income inequality. There have been many concerns that development of ICTs may result in a higher level of income inequality mainly because wealthy companies or individuals can more affordable to utilize advanced ICT and ICTs have replaced labor. However, there has been no such identified impact, at least in recent OECD countries. Rather, we can expect ICT development to play a role in lowering income inequality of a country.

ESS(Energy Storage System) is an important source that keeps power supply stable and utilizes electricity efficiently. For example, ESS contributes to resolve power supply imbalance, stabilize new renewable energy output and regulate frequency. ESS is predicted to be expanded to 55.9GWh of installed capacity by 2023, which is 30 times more than that of 2014. To raise competitiveness of domestic ESS industry in this increasing world market, we have disseminated load-shift ESS for continuous power supply imbalance with FR ESS, and also necessity to secure domestic track record is required. However in case of FR ESS, utility of installing thermal power plant is generally generated within 5% range of rated capacity, so that scalability of domestic market is low without dramatic increase of thermal power plant. Necessity of load-shift ESS dissemination is also decreasing effected by surplus backup power securement policy, raising demand for new dissemination model. New dissemination model is promising for $CO_2$ reduction effect in spite of intermittent output. By stabilizing new renewable energy output in connection with new renewable energy, and regulating system input timing of new renewable energy generation rate, it is prospected model for 'post-2020' regime and energy industry. This research presents a policy alternatives of REC multiplier calculation method to induce investment after outlining PV-connected ESS charge/discharge mode to reduce GHG emission, This alternative is projected to utilize GHG emission reduction methodology for 'Post-2020' regime, big issue of new energy policy.

Today, when innovation and creativity become increasingly important, management of human resources is a key factor for corporate performance and competitive advantage. Corporate are implementing and introducing various types of support methods for members to achieve goals and improve organizational performance. Organizational culture and organizational trust affect the cognitive and emotional state of members. Furthermore, it can bring about changes in organizational performance such as job stress and job satisfaction. From an institutional point of view, work-life balance is also a major factor affecting organizational performance. The imbalance between work and life leads to a decline in organizational performance, such as decreased morale and dissatisfaction with work. In relation to work-life balance, the low birth rate problem intensified and the importance began to emerge. Therefore, the government has implemented various policy support for workers' work-life balance, and the "52-hour workweek" is a representative example. This study analyzed the effect of organizational culture applying the competitive value model on workers' job stress. In addition, the mediating effects of overtime work per week and organizational trust were analyzed. Job stress corresponds to a prerequisite stage that affects job commitment, job satisfaction, and turnover intention. However, research measuring job stress by organizational performance is insufficient. In addition, there are few studies analyzing the relationship between overtime and organizational performance. Considering this, it is necessary to understand the influence relationship. The results of the study are as follows. First, a hierarchical culture increases the job stress of workers. On the other hand, innovation-oriented, relationship-oriented, and competition-oriented corporate culture reduce job stress. Second, a hierarchical culture has reduced trust in the organization, and other organizational cultures have increased trust in the organization. Third, relationship-oriented and competition-oriented organizational culture reduced overtime. Innovation-oriented, hierarchical-oriented culture increased overtime Fourth, organizational trust and overtime have the effect of mediating organizational culture and job stress. Based on these analysis results, this study presented academic and political implications.

This study is to examine loyalty building model which reflected differentiated traits of professional service to establish strong loyalty for gaining competitive edge. Professional service is where consumer can not easily predict the result of service as well as other common traits. It also has trait that is difficult to evaluate service satisfaction and quality even after using the service because knowledge imbalance between service provider and user is great. Therefore, in professional service, satisfaction and emotion that consumer perceives in the service use process will play critical role in loyalty formation. As a result, the model of this study divided dimension into responsiveness satisfaction which is satisfaction dimension of professional service use process, interaction satisfaction, technical satisfaction and structurally examined the relationship between emotional commitment and cognitive commitment and the relationship between dimension of commitment and loyalty. The analysis result show that dimension of satisfaction which perceived in professional service use process increases both emotional commitment and cognitive commitment and these commitments effect to loyalty formation.
