Using multi-molecular marker technologies and based on morphological criteria, the genetic relationship between Epinepheelus malabaricus and E, coioides was examined in the hope of resolving the long-standing issue of identifying these two species. Results showed that：（ 1 ） E. coioides and E. malabaricus should be identified as two species, the consistency of mitochondrial DNA cytochrome b gene sequence between E. malabaricus and E. coioides is 94.4%, and the genetic similarity by AFLP was 0.753 9 ; （2） Hybridization exists between E. malabaricus and E. coioides, the specific RAPD and AFLP fragments are found to be useful in the identification of these two species, and the genetic properties （both with exterior and inheritance） of hybrid is significantly biased to the male parents ; and （3） AFLP was a potentially powerful tool in constructing the genetic linkage map for these two groupers.

中国的资产证券化因其具有盘活存量资产、转移风险等功能在金融市场获得一席之地,但首例收益权类证券化产品的违约却暴露了其中的风险。收益权类基础资产未来现金流依赖于某一经营实体或实物资产的运营状况,这一本质特征使该类产品受原始权益人和外部经济风险的影响较大。本文通过对大成西专项计划违约的案例分析后得出的结论是,收益权类证券化产品主要受道德风险、资金混同、运营成本和外部经济等风险变量影响,并据此提出相应建议。
