The third-party funding originated from common law states. It gradually reflects its existence value in the field of commercial arbitration. However, related important issues, such as the rationality of this industry per se, the status of the funder in arbitration, the extent of the funder’s information disclosure, and the threshold of access to this industry, are still far from consensus. From the perspective of protecting economical vulnerable groups’legitimate rights and promoting substantial equality of the opposite parties, the third-party funding in commercial arbitration should be fully developed. However, in order to avoid excessive intervention by funders and form effective supervision to funding behavior, some limitations, such as promoting risk sharing of funder and recipient, ensuring the comprehensive information disclosure of funders, scientifically evaluating and reasonably setting the standard of industry access, should be taken so as to fully explore the function of arbitration, get close to the inner value core, and reasonably safeguard the autonomy of arbitration.
