(영문) Influence of Trade Pattern on Technology Innovation of SMEs in Korean Industry

4. Abstract

This thesis explores the Influence of Trade Patterns on Technological Innovation of SMEs in Korean Industry and consists 

of two separate studies. The first study study investigates the correlation of customer concentration and technological innovation 

across multiple industries and sectors in Korea using panel data for 2015–2019, and 37,472 SME observations. To increase the

 generalizability of research results, the fiest study group the subjects into six industrial classes based on a sectoral innovation system (SIS).

 The empirical results show that for SMEs, customer concentration generally has an inverted U-shaped relationship with technological innovation.

 For specialized suppliers, the science-based sectors show an inverted-U relationship, whereas the assembly/processing sector shows a positive 

relationship. To answer the question of whether subcontracting with large firms promotes the innovation endeavours of small and medium-sized

 enterprises (SMEs), the second study develops separate hypotheses for five industrial classes. This study addresses this question using panel data 

from 22,528 observations of Korean SMEs across all industries from 2015 to 2019. The findings indicate that exclusive subcontracting negatively

 affects innovation endeavours, specifically in the supplier-dominated, science-based, and assembly/processing industries. This thesis establishes 

and tests hypotheses by linking exclusive subcontracting and customer concentration, employs a quantitative approach in the context of SIS, and

 encompasses diverse industrial sectors, thereby providing logical alternatives for the various argues of existing research. The findings offer new 

quantitative evidence for sectoral innovation systems, emphasizing different innovation strategies for each industry. Specially, the findings have

 implications for the innovation strategies of SMEs, industries, and countries such as South Korea, where SMEs heavily rely on transactions with large firms.
