Abstract
For the past decade, human capital has been recognized as one of the crucial assets of any firm’s overall performance. Previous studies widely advocated a linear link between human capital and innovative firm performance, arguing that there are a variety of factors to examine if the relationship between human capital and innovative firm performance is to be properly understood. The focus of this study was to examine the effect of social capital on the relationship between human capital and innovative firm performance. Specifically, it examined the relationship between human capital and social capital and between human capital and innovative firm performance. It also examined the relationship between social capital and innovative firm performance. A total of 294 questionnaires were obtained from managerial staff in automotive companies in Malaysia and the data was analysed using the Partial Least Squares (PLS) test. The results indicated a direct effect between human capital and innovative performance. It was found that human capital is significantly related to social capital and that there is a significant relationship between social capital and innovative firm performance, indicating the ability of social capital to improve innovative firm performance. Finally, it revealed that innovative firm performance could be achieved by human capital through the role of valuable social capital and that good innovative firm performance leads to more prudent and sustainable organisations. The results provide pertinent implications for academia, policymakers and market players while also contributing to the research fields of strategic management, human capital, social capital and performance.
