Green finance is an important means of helping enterprises carry out green innovation,but there is also a certain amount of"greenwashing"in practice.Under the traditional green credit model,there is a principal-agent problem between financial institutions and enterprises due to infor-mation asymmetry and agency conflicts,which makes it difficult to realize mutual trust.Based on this,a digital green credit based on smart blockchain is proposed to solve the"information island"effect,and two evolutionary game models of traditional green credit and digital green credit are con-structed to investigate the impact of smart blockchain on green credit.The study shows that:(1)en-terprises"greenwashing"behaviors are an important factor affecting the healthy development of green finance;(2)smart blockchain can effectively alleviate the"greenwashing"dilemma by reduc-ing information asymmetry and establishing a reputation mechanism.The conclusion of the study en-riches the theoretical basis of"greenwashing"behavior and provides ideas for the sustainable devel-opment of green finance.
