In 2007, Bank of Communications Beijing Branch signed a loan contract with the TV series "Lotus Lantern Prequel" of Beijing Tianxingji Film and Television Culture Communication Company, which was the first copyright pledge loan in China film and television industry.

Subsequently, the bank copyright pledge loan model was further promoted. In 2008, Bank of Beijing entered the film and television industry and became a highlight of the film and television financing circle. Since Beijing started the docking of film and television industry and financial capital, the loans for cultural and creative enterprises issued by Bank of Beijing accounted for more than 90% of the total loans of financial institutions.

In May 2008, Bank of Beijing provided Huayi Brothers with a package loan of 654.38 billion yuan in the form of copyright pledge. This is the first "copyright pledge" loan without the guarantee of a professional guarantee company, and it is also the largest loan issued by the financial industry to film and television companies so far. In July 2008, Bank of Beijing signed strategic cooperation agreements with Poly Bona and Light Media respectively, providing 654.38 billion yuan loan support for two private film and television companies respectively.

Copyright pledge means that the debtor or the third party pledges the property right in its copyright according to law and takes this property right as the guarantee of creditor's rights. When the debtor fails to perform the debt, the creditor has the right to discount the money according to law or give priority to compensation with the price of auction or sale of the property. Among them, the creditor is the pledgee and the debtor or the third party is the pledger.
