A Study on Internationalization Strategy of Chinese Small and Medium-Sized Enterprises in the Post Global Financial Crisis Era

Li, Tian Guo,Kim, Chun Soo 한국상업교육학회 2015 商業敎育硏究 Vol.29 No.3

중국의 대형 국유기업은 오랜 기간 동안 중국 기업의 국제화전략의 선두자로 간주되어 왔다. 하지만 최근에 일부 민영기업들은 해외투자의 중요한 투자자로 나서고 있다. 중국의 중소기업은 국제시장에서 새로운 경제주체로서 앞으로도 점차 입지를 굳혀나갈 것으로 보여 진다. 본 연구는 중소기업의 중국에서의 발전현황에 대하여 살펴보고 중국 중소기업이 직면한 외부발전환경과 문제점들을 분석하면서 중국 중소기업의 국제화 전략에 대한 시사점을 제시하였다. 중소기업의 산업 업그레이드는 단순히 생산방식의 문제가 아니라 사회질서의 구축문제이기도 하다. 중소기업은 새로운 기술을 전통적인 생산방식에 도입시켜 자신만의 브랜드의 특성을 갖춰나가야 한다. 중소기업은 효율적인 기업시스템을 구축하고 인적자본의 효용을 극대화 시킬 것이 필요하며 기술혁신 능력을 키워나가야 한다. 또한, 중소기업은 중국 정부의 일대일로의 전략을 잘 활용하여 신흥국시장을 적극 개척해나가야 한다. 중국정부는 중소기업을 위한 금융기관을 설립하여 자금조달과 정책지원을 해나가며 수출을 강화해야 할 필요가 있다는 것을 시사하고 있다. Large state-owned enterprises in China have been regarded as dominant leaders in enterprise internationalization strategy for a long time. However, in recent years, some private enterprises have become an important subject of overseas investment. Small and medium enterprises (SMEs) in China are a new subject in the international market, which are expected to continue increasing their strength. This paper reviews the current situation of SMEs in China and expounds on how Chinese SMEs should pursue an internationalization strategy based on the analysis of the external development environment and existing problems of SMEs. The industrial upgrade of SMEs focuses not only on the problem of production mode but also on the problem of constructing social order. SMEs should combine advanced technology with traditional technology to provide their brand a unique characteristic. They should establish an effective corporate governance system, maximize human capital utility, and improve their own technological innovation ability. SMEs need to make full use of Chinese government's “One Belt and One Road” strategy to explore emerging markets. The Chinese government should also establish a financial institution, set up special funds for SMEs, and help SMEs to boost exports by providing government financial support and policy guidance.

Estimation of the Fundamental Period for Residential Buildings with Shear-Wall System

Chun, Young-Soo,Chang, Kug-Kwan,Lee, Li-Hyung Korea Concrete Institute 2000 KCI concrete journal Vol.12 No.1

This study focused on evaluating the reliability of code formulas such as those of the current Korean Building Code(KBC 1988). UBC 1997, NBCC 1995. and BSLJ 1994 for estimating the fundamental period of RC apartment buildings with shear-wall dominant systems, representative of typical residential buildings in Korea. For this purpose, full-scale measurements were carried out on fifty RC apartment buildings, and these results were compared to those obtained by code formulas and also by dynamic analysis. Although these code formulas are based on the measured periods of buildings during various earthquakes and building period varies with the amplitude of structural deflection or strain level, ambient surveys should provide an effective tool for experimentally verifying the design period to the completed building. This comparison shows that comparatively large errors are likely to occure when the code formula of KBC 1988 is used, and all the other code formulas are not sufficient to estimate the fundamental period of apartment buildings with shear-wall dominant systems. An improved formula is proposed by regression analysis on the basis of the measured period data. The proposal is for the servicebility stress level, but it can also be applied for seismic code in the regions of low seismicity similar to Korea.

Li, Tian Guo(이천국),Kim, Chun Soo(김춘수) 한국국제회계학회 2012 국제회계연구 Vol.0 No.45

중국의 상업은행의 규모가 급속히 확대되고 있으며 글로벌 금융위기이후 중국의 국유상업은행은 이미 세계 최대 은행으로 성장하였다. 중국의 중소기업이 경영 어려움을 겪고 있는 상황 속에서도 중국의 상업은행은 높은 수익률을 보이고 있으며 중국의 상업은행의 재무적 효율성이 점차 이슈로 되고 있다. 본 연구는 중국의 18개의 상업은행의 재무적 지표를 이용하여 멀티 인덱스 요인분석을 실시함으로써 중국의 상업은행의 효율성에 대해 고찰하였다. 요인분석에 의한 점수를 부여한 결과, 국유상업은행은 경영규모면에서 기타 상업은행에 비해 훨씬 높은 득점을 보였고 경영 수익 면에서는 작은 규모의 상업은행이 오히려 앞자리를 차지하고 있는 것으로 나타났다. 날로 치열해지는 경쟁 속에서 생존하려면 중국의 국유상업은행은 규모적인 확장보다도 경영 수익 면에서 금융제도 개혁과 기술 혁신을 통하여 효율을 향상해야 할 필요가 있다. Chinese commercial banks are expanding considerably. After the global financial crisis, China"s state-owned commercial banks emerged as the world"s largest banks. Although China"s small-and medium-sized enterprises (SMEs) face dilemmas, the country"s commercial banks still record high rates of return, thus making their financial efficiency an important issue. To perform multi-index factor analysis, this paper uses the financial indexes of 18 commercial banks, and examines their financial efficiency. The scores of scale are much higher than those of other commercial banks, whereas smaller commercial banks show more competitiveness in profitability. To survive in the increasingly competitive environment, state-owned commercial banks should improve business performance via continuous innovation and reform.

Li Tian-Guo(이천국),Kim Chun-Soo(김춘수) 한국국제회계학회 2011 국제회계연구 Vol.0 No.38

본 연구는 외국은행의 진입과 은행의 경영 효율성에 관한 연구들을 기반으로 외국은행의 신흥시장국가 은행에 대한 영향에 중점을 두었다. 본 연구는 여러재무지표에 의한 은행경영효율성 평가방법을 소개하였고 외자은행이 신흥시장국가의 은행 효율성에 미치는 영향들을 분석하면서 외국은행과 신흥시장국가 은행의 경영 효율성에 관한 부동한 견해들을 평론하였다. 분석 결과 외국은행이 시장진입초기에 국내은행보다 낮은 효율성을 보였지만 글로벌 M&A를 통하여 효율성을 제고하고 있다는 것이 발견되었다. 외국은행의 진입은 국내은행의 경영구조의 이행과 기술혁신, 비즈니스혁신 등 면에서 적극적인 역할을 하고 있다. 하지만 외국은행의 대출전략은 역효과가 일어나기 쉬우며 금융서비스시장의 분할을 가져오고 국내은행의 리스크가 커지면서 은행의 효율성에 유해한 것으로 나타났다. 외국은행의 역할은 투자 대상국의 경제발전수준과 랜덤 외생 요인의 영향에 따라 다르게 보이고 있다. This paper mainly presents a literature review and aims to organize the research on the relationship between the entry of foreign banks and operational efficiency of banks, especially in inducing the effect of foreign banks on the banks of emerging markets. This paper introduces some methods for measuring banks’ operational efficiency based on financial indicators, review the related literature on the effect of foreign banks on the banks of emerging markets, and assess the different viewpoints. Theoretical analysis and empirical evidence show that at the beginning of the entry of foreign banks, the efficiency of foreign banks is lower than that of domestic banks. However, through cross-border mergers and acquisitions, the efficiency of foreign banks increases gradually. The entry of foreign banks has a positive effect on the transition of operation structure, technological innovation, and business innovation of banks. However, the credit strategy of foreign banks has a likely adverse effect, leading to financial service market segmentation. Moreover, domestic banks are forced to take risks, which may decrease operational efficiency. The effect of foreign banks shows different results according to the different levels of economic development and random exogenous factors.

近年来, 全球经济环境正日益显现出动态、复杂、不确定性特征, 顺应这一特征, 全球学习能力成为跨国公司赢得竞争优势的关键。全球学习过程主要通过各海外子公司自主灵活的学习, 创造新知识, 并迅速有效地在整个跨国公司内部进行传递与整合来实现。因此, 海外子公司本地知识获取已经构成了跨国公司知识管理的重要组成部分。基于组织学习理论, 本文考察了影响海外子公司知识获取决定因素及本地获取的知识对企业绩效的影响。研究结果表明, 海外子公司的吸收能力和经验多样性对知识获取有正向影响, 但时间经验和网络嵌入性对知识获取没有显著作用。此外, 本土化战略和知识获取绩效评价标准对知识获取有显著影响, 同时海外子公司在本地获取的知识对子公司绩效有显著的正向影响。这些结果表明, 海外子公司自身学习能力和母公司对海外子公司的管理方式是影响知识获取的重要因素, 而海外子公司本地知识获取是跨国公司成功实施国际化战略的一个重要条件。 In recent years, international business scholars have been paying greater attention to MNEs global learning. This study developed an integrated framework, tries to analyze the determinants of knowledge acquisition and its impact on subsidiary performance. Our results show that absorptive capacity and diversity of experience have positive effect on knowledge acquisition, but intensity of experience and network embeddedness have no significant effect. In addition, we also find that localization strategy and subsidiary performance appraisal system stressing the development of new knowledge have positive effect on knowledge acquisition. Lastly, knowledge that acquired host country has positive effect on subsidiary performance. This finding implies that it is necessary to acquire local knowledge for successful internationalization. In conclusion, this study implies that subsidiary’s learning capacity and parent’s management style are important to knowledge acquisition and the extent of knowledge acquisition also important to subsidiary performance.

Structure Dependence of the Photoluminescence Properties of Eu³⁺ Ion-Activated <i>R</i>₂Mo₄O₁₅ (<i>R</i> = Y, La, and Gd)

Li, Huaiyong,Yang, Hyun Kyoung,Moon, Byung Kee,Choi, Byung Chun,Jeong, Jung Hyun,Jang, Kiwan,Lee, Ho Sueb,Yi, Soung Soo Electrochemical Society 2012 Journal of the Electrochemical Society Vol.159 No.3

<P>Polycrystalline powders of rare earth molybdates <I>R</I><SUB>2</SUB>Mo<SUB>4</SUB>O<SUB>15</SUB> (<I>R</I> = La, Gd and Y) with and without Eu<SUP>3+</SUP> ion-doped were synthesized by using a solid-state reaction. The structure, UV-visible diffuse reflectance spectra, photoluminescence spectra and their temporal decay of these compounds were characterized. The diffuse reflectance spectra indicate that all the compounds have strong absorption of near-UV light due to the optical excitation of the MoO<SUB><I>x</I></SUB> groups within the host lattices. Upon a near-UV light excitation, Y- and Gd-contained host lattices show very weak luminescence, while La-contained sample does not luminesce. When activated by Eu<SUP>3+</SUP> ions, all the compounds show intense red luminescence mainly originated from Eu<SUP>3+</SUP> ion <SUP>5</SUP>D<SUB>0</SUB>-<SUP>7</SUP>F<SUB><I>J</I></SUB> transitions. The luminescence can be obtained by exciting either into the host lattices or into Eu<SUP>3+</SUP> ion <I>f</I>-<I>f</I> transitions indicating efficient energy transfer from host matrices to dopant Eu<SUP>3+</SUP> ions. The photoluminescence properties of the compounds were studied as a function of the host lattice structure as well as the Eu<SUP>3+</SUP> ion concentration.</P>

Li, Chun-Shi,Zhang, Qinggao,Lee, Kwang-Jae,Cho, Sung-Won,Lee, Kee-Myung,Hahm, Ki-Baik,Choi, Suck-Chei,Yun, Ki-Jung,Chung, Hun-Taeg,Chae, Soo-Cheon Blackwell Publishing Asia 2009 Journal of gastroenterology and hepatology Vol.24 No.10

<P>Abstract</P><P>Background and Aims: </P><P>The cytokine interleukin (IL)-27 is composed of two subunits, Epstein–Barr virus-induced gene 3 (EBI3) and p28, and IL-27 is a novel IL-12 family member that mediates between the innate and adaptive immune systems. We previously identified four polymorphisms in the human <I>IL-27</I> gene and we suggested that the polymorphism of <I>IL-27</I> is associated with the susceptibility to asthma. IL-27 transcripts are significantly elevated in active Crohn's disease (CD) but not in ulcerative colitis (UC). To determine whether these <I>IL-27</I> single nucleotide polymorphisms are associated with the susceptibility to inflammatory bowel disease (IBD), the genotype and allelic frequencies of the <I>IL-27</I> polymorphisms were analyzed between the IBD patients and the healthy controls.</P><P>Methods: </P><P>Genotype analysis of the <I>IL-27</I> gene was performed by the single-base extension (SBE) method. The haplotype frequencies of <I>IL-27</I> for multiple loci were estimated using the expectation maximization (EM) algorithm.</P><P>Results: </P><P>The genotype frequencies of the g.-964A > G polymorphism in the IBD patients were significantly different from those of the healthy control group (<I>P</I> = 0.001). In both the UC and CD patients, the genotype frequencies of the g.-964A > G polymorphism were also significantly different from the frequencies of the healthy control group (<I>P</I> = 0.009). The frequencies of the AGT and GGT haplotypes were significantly different between the healthy control group and the IBD patient group (<I>P</I> = 0.00004 and 0.021, respectively).</P><P>Conclusion: </P><P>Our results suggest that the g.-964A > G polymorphism of the <I>IL-27</I> gene located on the <I>IBD1</I> locus might be associated with the susceptibility to IBD.</P>
