It may be safe to say that few SMEs could benefit on global markets under the rapid changing business environment owing to their scarcity of market information, financial resource and technological capability etc. However, some SMEs could succeed in breaking through their business activities on domestic and global markets by using their unique strengths such as development of components for TNCs and exercising vigorous entrepreneurship in the globalizing economic system. Due to the intensive competitions between SMEs, they need to develop either the only one or the best product for markets that may be one of the most important survival factors. Yuyang DNU represents one of these cases which indicate how a SME made a break through to access to Samsung Electronics and LG Electronics for delivering its high-tech components instead of simple parts. This strategy enables the company to overcome all hurdles to enter the EU market along with South Korean conglomerates. This paper focuses on strategies and entrepreneurships of Yuyang DNU how it made a quantum jump from a small business to a medium sized company in order to generate a shared growth with TNCs continuously. It also argues which role of entrepreneurship has played in taking high risks to be chosen as a trustful partner for Samsung Electronics and LG Electronics.
