摘要
基于新实证产业组织理论的Lerner指数是经典的测度市场竞争的方法,而Boone指数是基于有效结构假说的测度竞争的新方法。国外学者对这两种方法的大量研究发现,Boone指数受经济周期影响小,且稳健性和理论解释力优于Lerner指数,但仍然处在不断完善中的两种指数,在实证研究中很难比较出孰优孰劣。两种方法有不同的理论根基和出发点,银行业的市场竞争研究也需要使用多种测度竞争的方法,以获得准确和稳健的结果。
Lerner index is a classic measure of market competition based on the new empirical industrial organization theory, and Boone indicator is a new method to measure competition based on the efficient structure hypothesis. A large number of studies of foreign scholars finds that, Boone indicator is less subject to economic cycles, and is more prudent and has the more theoretical explanatory power than the Lerner index. The two indices have been improved constantly still, and it is difficult to compare which one is better in empirical research. Each method has its theory base and origin, and the research on banking competition should employ more than one method to be more accurate and prudent.
