    實證研究結果表明,近年來,我國證券市場的信息操縱行為處于高頻率狀態, 《證券法》的有關處罰規定在現實中沒有得到嚴格的實施,懲罰力度不足以有效遏止市場的尋租沖動,在市場有效監管上,不僅稽查的概率偏低,而且稽查的成功率也有待提高,合理改進稽查概率、稽查成功率、懲罰力度、中小投資者抗租能力等相關參數,是提高市場效率的有效途徑。

First, this paper gives an introduction of some methods of unequal probability sampling, their estimators and variance estimators, including sampling with pps with replacement, methods of sampling without replacement suggested by brewer, durbin, sampford, des raj, murthy, rao - hartley - cochran. then, at the basis of rao and bayless ' s study, we consider that population can be splited two random subpopulations, which are respectively drawn from different infinite super - populations, and compare the stabilities of estimators of the methods that given above. we find that the minor difference between two super - populations has great effect on the efficiency of the estimators for the population with moderately large coefficient of variation ( c. v. )

( x )較大的總體而言,兩個超總體之間的微小差異將對估計量的穩定性產生很大的影響,從而說明rao和bayless的比較結果還不夠完善。
