Abstract: Abstract:whether the external factors or the internal factors determinate firm's product innovativeness is a debatable topic,from the point of industry economics theory,the external environment determinate firm's product innovativeness,while from the perspective of strategy management theory,the firm's core competence determinate product innovativeness.in order to bridge this theoretical gap ,both external environment and core competence have been integrated into one model as independent variables.after using a survey date from 127 firms which analysed by multiple regression ,we found that the positive influence of external environment on product innovativeness is significant,while the positive influence of core competence on product innovativeness is not significant,what's more,core competence will negative moderate the relationship between the external environment and a firm's product innovativeness.
