The paper discusses the reasons for the low development level of Eastern Croatia, as well as possible ways of overcoming this situation. The revenues of local and regional self-government are frequently insufficient to finance development projects. Different characteristics of these fiscalities, such as permanent income and changes in managing this income can reduce the costs and result in more prudent and economical stewardship of local and regional authorities. This refers primarily to concentrating public resources in one commercial bank, which would establish a kind of partnership between the bank and the local community. The paper further examines the influence of ownership structure and bank's domicile on business policies of the banks operating in Eastern Croatia. The proposed changes together with new ways of financing, such as issuing securities, could generate new positive effects in financing regional development.
