The study looked at how different types of knowledge and resources affect the efficiency of small businesses in China. They found that having skilled employees (human capital) can make a business more efficient, but having lots of money (financial resources) can weaken this effect. On the other hand, having good relationships with others (social capital) and understanding customers' needs (customer capital) may not directly improve efficiency, but having financial resources can help strengthen these connections and make the business more efficient. The study suggests that small business owners should use their money wisely, along with their employees' skills and understanding of customers, to improve efficiency.
