This study aims to examine the intermediary roles of employee performance between high performance work system (HPWS) and its operational performance on the resource based view. Taking into account the unit of analysis, this study used a hierarchical linear modeling analysis in order to test rigorously the association between HPWS at the organisational level and employee performance at the individual level. For this empirical test, Human Capital Corporate Panel (HCCP) data including 316 firms and 7,872 respondents (including 923 team leaders) were used. To meet the unit of analysis and test the mediation effect, data at the individual and team level were aggregated into the organisational level. The empirical results show that HPWS have a positive impact on operational performance as well as employee performance such as job satisfaction, organisational commitment and organisational trust. Regarding the mediation effect, job satisfaction and organisational trust mediate between HPWS and operational performance. Theoretical implications are discussed in conclusion.

Extant studies have explained that firm's innovations including technological product and process innovations contribute to its competitive advantage and growth, thereby supporting competitiveness and growth of industry. These studies, however, have focused mainly on the role and effect of technological change that is primarily measured by the patent numbers and R&D intensity. Aside from these traditional streams, there has been growing interest on the impact by various dimensions of innovation including non-technological innovations. Apart from the discussions on the dimensions and scope of innovation, stages or processes of innovation also have been studied. Extant studies on innovation process model, however, has limited its interests in the structure of the transformation of knowledge. This study have established a comprehensive model embracing operational and financial performance to investigate the causal paths between innovation and firm performance. Using multi-level generalized linear model with path analysis, this study have found results as follows: First, the processes from innovative activities to innovation output and outcomes including operational and financial performance at firm level were verified. Secondly, the influence of innovation decreases gradually as the distance away from the direct outputs of the innovation increase in the direction of financial outcomes. Third, the effect of innovation on the sales growth rate is higher for small businesses than for medium-sized businesses. The effect of innovation on the profit rate, however, is significant only for medium-sized businesses. For large businesses, innovation has no positive significant impact on any financial performance at all. Fourth, Fourth, the appropriability of innovation has positive impacts on innovative performance, patent applications, and operational performance.

This study examined the relationship between dynamic capabilities and innovation performance and the mediating effect of exploration/exploitation operational capabilities as well as the moderating effect of exploration/exploitation IT capabilities. The results are as follows: seizing capability and reconfiguration capability had positive effects on incremental and radical innovation performance. Exploration and exploitation operational capability had positive effects on incremental innovation performance. Furthermore, exploration operation capability had a positive effect on radical innovation performance. 'Exploration operational capability-exploration IT capability' had moderating effects on 'exploration operational capability-exploitation IT capability', and 'exploitation operational capability-exploitation IT capability' on incremental innovation performance. Lastly, 'exploration operational capability-exploration IT capability' had a significant mediating effect on radical innovation performance. This study is the first empirical research that divides the effects of dynamic capabilities into direct and indirect effects, and the operational/IT capabilities into exploration and exploitation.. Dynamic and operational capabilities play a complementary role in adapting and evolving companies.

To derive an efficient operating system for business incubators, this study examined the operating performance according to incubator operating system and incubator manager. The survey targets were tenants of business incubators and factor analysis. Regression analysis was performed according to the reliability analysis, correlation analysis, regression analysis and parameter using the 19 Ver program SPSS analysis. As a result, the business incubators and business incubators operating system were found to be an important factor and among these, the H / W and system S / W systems were identified as significantly influential factors. On the other hand, this hypothesis of the performance of the support system and characteristics of the incubator manager was rejected for the variable parameters, which always appear to influence the other characteristic factors of the manager. Operational performance can be divided into an incubator performance center and tenant's performance, and the performance of the tenants were analyzed by the significant effect on the managers characteristics.

This study analyzed both the effect small and medium-sized suppliers' SCM capacity on the performance and how the moderating effect of demand uncertainty as an environmental factor affects this relation. The study is based on the data collected from the survey of small and medium-sized suppliers operating in electronics, metal, machinery, automobile, and textile. It analyzed the results of survey targeting suppliers of these areas by using structure equation modeling. According to the analyzed result, the relation capital of small and medium-sized supplier affects the performance, but there is no relation between coordination capability and the performance. In case of the moderating effect of demand uncertainty, while there is a positive moderating effect of demand uncertainty between relation capital and performance, there is no any moderating effect between coordination capability and performance. It turns out that the relation capital keep having a positive effect on the performance even if there is a demand uncertainty.
