本文利用新出清代浙南石仓契约和会簿文书,通过对石仓会社在土地市场中经济活动的分析,深入讨论了会社组织的社会特性。本文认为,清代石仓会社置产活动频繁,但总体上享有某种交易价格的保护和优惠。清代石仓会社的这类市场表现,与它们的"公共"属性颇有关联。一方面会社具有公共组织的特征,往往代表某种集体的利益,与个人买主有所不同;另一方面在会社内部也常遵循着更公平的组织原则,会内成员之间更为平等。相比于等级色彩明显的宗族组织,石仓会社更具有"公共性"。

运用文献资料法和逻辑分析法,围绕十八届三中会全面深化改革的总体部署,分析全面深化体育改革所面临的改革方向、改革关键点、改革突破口以及改革路径等几个基本问题。研究认为:改革方向迷茫是当前全面深化体育改革面临的首要问题,全面深化体育改革必须遵循市场经济体制改革的基本方向,改变单纯依靠国家(政府)办体育的发展方式,走市场化、社会化发展道路和发展方式。全面深化体育改革的关键点在于转变政府体育管理职能,在科学理解转变政府职能的基础上,明确界定政府在发展中的责任主体角色,实行责任主体与实施主体分离。全面深化体育改革的突破口应选择在培育、发展和完善体育社会组织方面,以培育健全成熟完善的体育社会组织实现体育管办分离,推进体育的社会化和市场化发展。在具体实施改革时,应积极发挥"顶层设计"的宏观指导作用,将宏观层面的"顶层设计"与微观层面的"摸着石头过河"两种路径结合起来,确保深化体育改革的各项措施朝着既定目标顺利实施与推进。
