长江上游地区实施农村创新战略研究

农村创新分为原始要素主导、初级要素主导、中级要素主导和高级要素主导四个阶段,包括需求创新、要素创新、产业创新、环境创新、组织创新、体制创新和文化创新.长江上游地区农村创新总体上处于初级要素主导阶段,并存在七大障碍.因此,长江上游地区农村创新的基本模式是政府主导型的,必须全面建立初步的农村创新体系;构筑利于中级水平创新的钻石结构,推进重点农村区域的创新;打牢农村小康的环境基础和村民素质基础,突破难点区域的农村创新.     

The relationship between major-league sports’ official sponsorship announcements and the stock prices of sponsoring firms

This study presents analysis of the impact of “official product” sports sponsorships with the National Football League (NFL), Major League Baseball (MLB), the National Hockey League (NHL), the National Basketball Association (NBA), and the Professional Golfers Association (PGA) on the stock prices of sponsoring firms. The primary finding of the study is that, in the main, announcements were accompanied by increases in shareholder wealth. The 53 sponsors analyzed experienced mean increases in stock valuations of about $257 million. A multiple regression analysis of firm-specific stock price changes and selected corporate and sponsorship attributes indicates that official product sponsorships with the NBA, NHL, and PGA and those with smaller market shares were associated with the largest gains in share prices. Although corporate cashflow (a proxy for agency conflicts) is statistically unrelated to shareholder approval, sponsorships by high-technology companies were associated with stronger stock price reactions than otherwise. Finally, product congruence with the sponsored sport was positively related to changes in stock prices. T.

关于提高印花税税率的冷思考

印花税税率调高会带来交易费用的上升,可以抑制短期投机,从而在一定程度上稳定市场。但在我国证券税制不完善的情况下,股票交易的印花税存在缺乏法律依据、税种错位、职能错位、征收范围错位等问题,其身兼数职,扮演了多税种合一的角色,仅靠调整印花税难以真正达到压缩股市泡沫、促进资本市场健康发展的效果,还会带来印花税其他职能的丧失。因此,开征差异性证券交易税,对印花税进一步改革已迫在眉睫。

四化联动:小城镇发展的新思路

发展小城镇是农村城市化的必然选择，而小城镇的发展程度和水平，则依赖于农业产业化、农村工业化、农业人口知识化及城市化的互动作用。为了使农村城镇化有质的飞跃，必须以工业理念管理现代农业，以园区管理理念整合农村工业，以育人理念提高人口素质，以城市管理理念提升城镇水平。     

论LLSV法律来源论的缺陷性

拉普特等人用数据来表明,法律来源于普通法系国家比法律来源于大陆法系国家特别是法国大陆法系国家能更好地保护投资者,而德国大陆法系国家和斯堪的纳维亚国家则介于这二者之间。公司所有权的集中程度在他们的研究中被认为是对投资者保护差的一种适应性反映。在本文,我们用中国和其他国家的证据来说明政治经济因素比法律来源论能更好地解释在中国的转型经济中对小股东保护差的原因。我们认为中国上市公司所有权非常集中的原因是政府决策的直接结果,也认为政府控制绝大部分上市公司在某种程度上减弱了对小股东的保护。
