Abstract:Based on property rights, enterprises are divided into stateowned ones and non stateowned ones. Considering the lag of impact, a bidirectional model was designed for an empirical research on the stagecrossing interaction between CSR (corporate social responsibility) and FP (financial performance), with the data of Ashare listed companies in Jiangsu, Zhejiang provinces and Shanghai municipality in 20102014. The results show that, the higher current CSR is, the better current FP will be; the positive effect by current FP on nextstage CSR is greater than that on current one; the nature of stateowned enterprises impairs this reciprocity. Enterprises should recognize the significance of CSR and make it a driving force for sustainable development.
