As the IT labor captures an increasing proportion of the total labor, it is important to analyze the contribution of IT labor to national economy. Although there has been abundant research about the effect of IT investments, it is difficult to find a research about IT labor's economic contribution. Most prior studies on the effect of IT investment have focused on the effect of IT capital investment. This paper empirically explores whether and how IT labor makes contribution to Korean economy. And also this paper examines the economic contribution of IT experts and semi-experts in Korean industries over the 2000 to 2007 period, using production function framework and panel data set for 24 industries constructed from 'Input-Output table' and 'Research on Wage Structure Survey'. Based on the full sample of 120 observations, this study finds that a 1% increase in IT labor wage is associated with 0.042190% increase in added value. In the case of non-manufacturing industries on the sample of 50 observations, this study finds that a 1% increase in IT labor wage is associated with 0.074908% increase in added value. And in the case of IT experts (separated from IT semi-experts), this study finds that a 1% increase in IT expert's labor wage is associated with 0.013957% increase in added value of all industry. This study provides implication for policy makers and managers. The results suggests that non-manufacturing industries can capture further benefits by increasing investment in IT labor. Building on this study, future research should examine the impact of IT labor at a more detailed industry level and the firm level.

Investments in factory automation do not guarantee productivity enhancement. Much unknown losses may exist in all aspects of production resources such as in material, manpower, machine, etc. Total productivity in korean firms has decreased in recent years. Labor and capital productivity index fall to 0.82 point and 0.73 point, respectively. Investment in FA has Increased rapidly. Tangible fixed assets per capita increased 64% during the past Three years. But, this high-technology oriented systems such as NC, robotics, CAD/CAM, FMS, etc. are often out of keeping with the old production process control, and thus do not result in satisfactory performance. This review paper concerned with these problems and suggests some future directions for production control and development strategy of korean firm's.

Entering the 1990s, Korean economies experienced the high-cost and low-efficiency situation which evetually caused many Korean firms led to relocate their production facilities to lower labor cost countries. This paper aims to draw out the characteristics of FDI and to evaluate the impacts of FDI in manufacturing sectors. Firstly, we try to categorize the indutries into three groups, labor intensive, capital intensive, and the technology intensive industries figuring out the characteristics of FDI of Korean firms. Secondly, we compare the three categories by grouping high and low foreign investment areas using value added data. Thirdly, we analyse the impacts of foreign production relocation the number of firms, production volume and jobs creation in Korea during the period 1991-1996. This paper concludes that the FDI of Korean firms concentrates to labor intensive industry and the hollowing effect caused by FDI was observed partially in the labor intensive industry.

Bio-ethanol is a promising alternative energy source for reducing both consumption of crude oil and environmental pollution from renewable resources like lignocellulosic biomass such as wood, forest residuals, agricultural leftovers and urban wastes. Based on current technologies, the cost of ethanol production from lignocellulosic materials is relatively high, and the main challenges are the low yield and high cost of the hydrolysis process. Development of more efficient pretreatment technology (physical, chemical, physico-chemical, and biological pretreatment), integration of several microbiological conversions into fewer reactors, and increasing ethanol production capacity may decrease specific investment for ethanol producing plants. The purpose of pretreatment of lignocellulosic material is to improve the accessible surface area of cellulose for hydrolytic enzymes and enhance the conversion of cellulose to glucose and finally high yield ethanol production which is economic and environmental friendly.

Energy holds key to economic growth and prosperity of India. Currently, India has very high-energy import dependence, especially in the case of crude oil (80%) and natural gas (40%). Even coal import has been increasing over the years. Considering India's population growth, emphasis on manufacturing, production, and service industry, energy consumption is bound to increase. More fossil energy consumption means greater dependence on energy import leading to widening trade deficit and current account deficit. Therefore, exploitation of indigenous renewable energy production is necessary. The paper reviews the progress and growth of renewable energy production, distribution, and consumption in India. The paper highlights some of the enablers of renewable energy in India. The authors discuss the opportunities and challenges of increasing share of renewable energy to reduce energy import and address issues of energy security in India. The findings suggest that India is ready for a quantum leap in renewable production by 2022.

Purpose - This study aims to seek various plans to maintain the advancement of the overseas and domestic employment scenario through a case analysis of the Japanese industry, which maintains domestic employment while promoting the overseas advancement of companies despite having a similar industrial structure as Korea. The study further intends to derive insightful implications for Japanese manufacturing companies and government policies. Research design, data, and methodology - We selected four companies from the Japanese manufacturing industry. Being companies that were successful in increasing the domestic employment scenario while advancing in overseas markets. We utilized several secondary data sources including Japanese newspapers and report literature. Results - Previous studies have shown a negative relationship between Foreign Direct Investment (FDI) or offshoring and domestic employment. However, our results showed this relationship with respect to the Japanese manufacturing industry as follows: 1. FDI for developing overseas markets does not decrease domestic production. If Japanese companies change their strategy from exports to overseas production, there will be a consequent decrease in domestic employment of Multinational Enterprises (MNEs). However, the local production that plans the sales expansion of a foreign market does not substitute domestic production. 2. Several case studies illustrate that, as the production of final goods is expanded in foreign countries, there is a corresponding increase in the export of intermediary goods from Japan. In this case, if the production process of Japanese companies is promoted in foreign markets, the amount of exported material and parts from Japan will consequently increase. 3. It is difficult to consider that the establishment of subsidiary companies in foreign countries by manufacturing companies for wholesale, retail, and services decreases domestic employment. This is because the international development of these industries needs expatriates, expatriate training organizations, and research and development (R&D) activities. 4. When there is overseas demand, the growth of local management activities is expected to increase the work of the overseas business department in the head office in Japan, if competitiveness can be secured for better localization and management speed. 5. The conversion of the domestic manufacturing industry into high value-added production is necessary. The relocation of domestic production to foreign markets decreases domestic employment. To prevent this, the upgradation of domestic production bases, including high value-added production, and R&D capability need to be strengthened. Technology-based companies must develop new technology, patents, processes, and so forth, which require extensive human resources for R&D. Conclusions - Domestic medium-sized companies that are capable of consistently supplying high value-added products should be actively encouraged to deploy into and develop overseas markets. Further, this paper considers the necessity of a guidance policy that provides suggestions for overseas deployment, by the initiation of the government, to companies that cannot do so due to the lack of foreign experience or decisions by the CEO, despite having the relevant capability and technologies to supply high value-added products.

본 연구는 중소기업의 개성공단 및 베트남에 대한 직접투자 결정요인을 분석하고, 향후 북한 비핵화에 따른 남북경협 활성화시 대북투자 경험이 없는 베트남 투자업체 중 대북투자 의향이 있는지, 있다면 그 이유가 무엇인지, 대북투자 경험이 있는 개성공단 입주업체와 비교 분석하여 해외기업의 개성공단 및 북한 경제특구 유치로 U턴시켜 국내 일자리 창출 및 남북경제 활성화에 기여하는데 그 목적이 있다. 분석결과 개성공단 및 베트남 투자기업의 대부분은 값싼 노동력 활용, 저렴한 공장입지, 현지시장 판매·개척, 제3국 우회수출 생산기지 등의 목적으로 진출하는 것으로 나타났다. 이는 해외직접투자이론상 현지시장 판매 및 확대를 위한 시장추구형 투자(Market seekers)와 인건비 등 생산요소가격 차이를 활용한 생산효율추구형 투자로(Production-efficiency seekers) 나눌수 있는데 이는 최근 나이키, Apple, Amazon 등 글로벌 기업들의 해외직접투자 패턴과도 일치하는 것으로 보인다. 그러나 북미 비핵화 협상으로 대북 경제 제제조치가 완화, 해제되더라도 베트남 투자기업의 대북 투자의향은 12.3%로 매우 저조하게 나타났는바, 이는 북핵 Issue로 개성공단 폐쇄와 같이 정치적 Risk로 인한 북한 경제특구 폐쇄가능성을 가장 부담스러워 했으며, 또한 경제특구 폐쇄시 국가의 손실배상 조치가 매우 부족하다고 느끼는데 있다. 따라서 향후 남북경협 활성화를 위해서는 앞서 얘기한 애로점을 해소하고 가칭 "남북경협진흥공사"와 같은 기관을 설립하여 대북지원기관의 중복업무를 방지하고 Onestop fullservice로 신속하게 지원할 필요성이 있으며, 섬유,봉제,신발과 같은 영세 중소기업의 대북 진출을 위한 진출 초기에는 적극적인 정책금융 지원이 절실히 필요하며 이를 위해 정부와 민간금융기관 공동으로 5,000억원 규모의 펀드를 조성하여 운영할 필요가 있다.

We evaluated industry growth and employment effects of every possible pairs of 22 manufacturing sectors and 16 regions (i.e, 352 region-sectors). We used annual data of manufacturing sectors from 2008 to 2014 for the evaluation. The evaluation comprises of two steps; We first find several region-sectors that outperform others with respect to the effects of industry growth and employment, which are measured by location quotient analysis, shift share method, employment to GDP ratio and employment elasticity. In addition, cross-efficiency analysis follows to classify region-sector pairs into two sub-categories : efficient region-sectors that deserve to hold the current level of investments and inefficient region-sectors where we should consider efficiency improvements. To examine the efficiency, R&D investment, employment size, and capital investment were used as input factors and production volume, added value, changes in employment size, changes in annual salary per capita were used as output factors. For region-sector pairs that have outstanding growth and employment effects but are inefficient, we employed a CCR DEA model and analyzed how much to adjust the values of input and output factors to improve the efficiency scores. The analysis results showed that inefficiency is mainly due to several factors such as R&D investment, changes in employment size and changes in annual salary per capita.
