This paper reviewed the relationship between innovation(organization innovation, personnel innovation, product innovation, process innovation) and firm performance in small business. Based on the responses from 218 firms, the results of multiple regression analysis showed that personnel innovation, product innovation, and process innovation effect positively on all firm performance(sales, profit, market share, customer satisfaction), and organization innovation effects positively only on market share and customer satisfaction. The results of hierarchical regression analysis showed that technical innovation(product innovation, process innovation) effects more positively on sales, profit and customer satisfaction than administrative innovation(organization innovation, personnel innovation).
