谁能帮我翻译一下下面的汉语啊
Landes and Posner（1981）认为,市场势力一词是指单个或一组联合的厂商对价格的一种影响或控制能力,即厂商将价格提高到完全竞争水平之上、同时价格上涨不会带来大部分销售额的迅速丧失以致于提高价格无利可图并且必须被取消的能力.
Pindyck and Rubin(2002)也指出市场势力是指在一个不完全竞争的条件下提高价格和限制产量的能力.
它反映了企业在竞争水平（边际成本）之上确定对自己有利的价格的能力,这就使得那些具有市场势力的企业能够通过将价格定在高于市场具衡价格的水平上由此获得超额利润.
美国司法界对市场势力所下的权威定义是“控制价格或排除竞争的权力”；横向合并准则则认为“市场势力是指在相当长时期内将产品价格维持在竞争价格以上的能力”.
