基于存在多个竞争性平台的理论框架,研究了平台的两种排他性合约形式:传统排他性合约和“二选一”合约.区分了优势平台使用这两种排他性合约动机的差异,并分析了不同形式的排他性合约对市场竞争和市场各方参与者收益的影响.研究结果表明,平台之间以及卖家之间的差异化程度是决定优势平台提供不同形式排他性合约的动机以及排他性交易对市场参与者产生的影响的核心因素.当平台之间以及卖家之间的差异化程度均较小时,优势平台选择提供传统排他性合约;而卖家之间的差异化程度较大时,优势平台选择提供“二选一”合约.尽管不同形式的排他性交易均会降低消费者剩余和总福利水平,但对其他竞争平台和卖家利润的影响是不确定的.传统排他性合约可以同时降低多个竞争平台的利润,而“二选一”合约则可以同时降低多个卖家的利润.本研究为平台不同形式的排他性交易行为提供了理论解释.

西路庐剧是我国非物质文化遗产庐剧的主要分支,皖西庐剧是西路庐剧20世纪50年代后的转型体。新中国成立后,为了让传统戏曲焕发出新的光芒,展开了一系列改造和创新。凭借一系列优秀剧目,皖西庐剧走出安徽,走向全国。皖西庐剧之所以能够取得不俗成就,与其对西路庐剧传统唱腔的继承与突破密不可分。在唱腔方面,皖西庐剧既有对西路庐剧的传承,也有变革,并且随着时代发展不断变化。在20世纪50—90年代,唱腔传承与变革主要体现在几方面:在主腔方面,核心音调得以保留,同时旋律复杂化,衍生出一系列新唱腔;在花腔方面,既传承了传统花腔,也编创出新花腔;在音乐程式上,一直保留着稳定性和格律性特征,同时程式化内容也有一定拓展。深入研究皖西庐剧唱腔,尤其是皖西庐剧对于西路庐剧唱腔的传承与变革,可以为推动当前地方戏曲走出低迷困境提供借鉴和助力。
