基于二维Hotelling模型,构建同时考虑平台与商家差异化的博弈模型,探讨强势平台排他策略选择的原因以及影响.研究表明:首先,强势平台存在两种排他动机,分别为“垄断驱动-排他”和“差异化驱动-排他”.强势平台较低的佣金、平台间较低的横向差异化水平、较高的纵向差异化水平以及产品间较高的横向差异化水平均会强化“垄断驱动-排他”,弱化“差异化驱动-排他”.其次,对弱势平台而言,强势平台的“差异化驱动-排他”对其同样有利.弱势平台可以通过适当降低佣金、增加平台间的横向差异化程度、降低平台间的纵向差异化程度,来避免“垄断驱动-排他”的出现.最后,激烈的产品间竞争能够激励强势平台的“差异化驱动-排他”,降低产品间的竞争水平,进而提升商家收益.研究结论有助于厘清强势平台排他策略的驱动因素以及区分排他策略对各方的不同影响,对强势平台的监管和平台行业的反垄断具有重要意义.

1966年7月,全国公安部队重新划归中国人民解放军建制,仍然继续担负原公安部队的内卫和边防任务。20世纪70年代初,随着国内外形势的变化,中央开始采取措施,逐步恢复武装警察队伍。1973年10月,边防检查站移交公安机关建制领导,改为人民武装警察。1975年10月,国务院、中央军委决定将原隶属各军分区、武装部领导的县、市中队移交公安机关管辖,改称人民武装警察中队。中共十一届三中全会后,武警部队的重新组建工作全面加速。1980年1月,人民边防武装警察部队正式成立。8月,中共中央决定将内卫执勤部队移交公安部门。这是武警体制全面恢复的重要的、关键性的一步。1982年6月,中共中央决定重新组建中国人民武装警察部队。1983年4月5日,中国人民武装警察部队总部正式成立。这是我国武装力量体制的一项重大改革,是强化国家机器的一项战略措施。武警部队建设进入了持续稳定发展的新时期。

校长、士吏与游徼,是秦汉县下治安官吏的重要构成。秦及汉初,亭的长官不称亭长,也不称亭啬夫,多称校长。校长是有秩吏,署亭任职,不持亭印。县市亭负责人称亭啬夫,文书中省称“亭”,持亭印。二者并不相混。刘邦“为泗上亭长”,乃是《史记》用武帝时职官称谓予以比附,应为泗上亭校长。秦代“亭长”秩级高于汉代中期以后,刘邦禄秩高于萧、曹,同属“豪杰吏”,身份并不特别低微。士吏在早期各县普遍存在,以捕盗为主责,相较于校长主亭,士吏主鄣,受令可领导鄣亭警备力量,并在乡亭徼循,“远其县廷”。西汉武帝以降,军事色彩突出的士吏、发弩、髳长,已退出日常职官序列,各县不复常设;亭校长均称亭长,秩级降低,地位下降;加之县尉所属尉史改属县廷,县级武吏系统多有变动。与此同时,游徼作为外部吏,由县廷功曹署任,负责徼循。东汉在“部游徼”的基础上,复增“部贼捕掾”。后者受县廷所遣,因事派出,更有助于贯彻上级命令,凸显县令长的集权趋向。县下治安官吏的设置及调整,反映秦汉王朝由战时体制转向日常行政体制的历史变迁。
