以Brown等人提出的共同基金“竞赛假说”为基础,通过Spearman检验考察中国开放式基金是否符合“竞赛假说”得出,总体来看中国开放式基金的“竞赛假说’’并不明显,不同的年份有不同的表现;新基金比老基金表现出了更为典型的“竞赛假说’’特征;Spearman相关系数检验表明新基金比老基金的投资策略更为稳健。
Based on Brown's "tournaments hypothesis" of mutual funds, with statistics and Spearman tests, this paper inspects whether China's open-ended fund is or not consistent with "tournaments hypothesis". Studies have shown that as a whole, China's open-ended fund is not-obviously consistent with "tournaments hypothesis", and different years have different performance; new fund is more consistent with "tournaments hypothesis" than old fund; Spearman-test correlated coefficient shows that new fund's investment strategy is more robust than old fund's. This paper analyzes the reasons of the above-mentioned results, and gives the relevant policy recommendations.
