The findings imply that firm operating efficiency can be improved by investing in human capital, structural capital, and financial capital. Statistically, human capital is the most significant of the three proxies of IC. If we were to set the statistical significance at the 1% level, structural capital would have no impact on the operating efficiency of the life insurance companies. To be able to provide responsive service to customers in China, life insurers probably need to fully utilize their human capital. Without a large amount of human capital, they might face difficulties in running many branches across China. In addition to training, Chinese life insurers should thus continue to recruit and retain capable employees since they are the most important intangible assets of a firm. According to Ahangar [28], employees are the source of collective knowledge, competency, experience, and skills needed to provide goods or services and solutions to customers. Life insurers should also not overlook structural capital, which is the supporting infrastructure and process of human capital. Efficient spending on administrative needs is essential since the eventual result is better overall efficiency. Life insurers can better serve their customers with great human capital and structural capital, which will ultimately result in more outputs or earnings. In summary, investing in intellectual capital is the key for life insurers to achieve better performance.
