关于手写汉字的切分算法的探讨

汉字识别是模式识别的一个重要分支。识别过程包括光电扫描,模数转换,预处理,模式表达,判别。其中预处理阶段的字切分是整个识别过程的一个重要组成部分,也是难点之一,使如污点的处理,粘连问题,字误切后的重新合并问题等,都给我们的准确切分带来许多麻烦。本文以确定的竖写字贴为处理对象,对手写汉字的字切分做了比较细致的工作,特别就以上提高的问题都是提出了比较实际的解决算法,整体上取得了良好的切分效果。     

外商直接投资对中国企业创新的外溢效应研究：基于垂直联系的视角

利用世界银行对中国的企业调研数据,本文从垂直联系视角考察了FDI对中国企业创新的外溢效应。分析的结果表明,垂直联系有利于企业创新与技术溢出。并且,与水平溢出相比,垂直联系渠道发生的溢出更为显著。对垂直联系影响因素的分析表明,拥有外方合作伙伴、位于工业园或出口加工区、加入商业协会、企业拥有较高的国内市场份额、国内市场进口产品份额较高、受国外教育经理的人数比例越高,这些因素均有利于企业垂直联系的建立。然而,企业的出口倾向对前后向联系的作用相反。

信息税及其对证券市场会计信息披露问题的治理

随着我国证券市场的发展,证券市场的法定信息披露、信息披露监管、会计准则建设等信息的公共服务越来越重要,而证券市场现行较为单一的证券交易税收制度作为公共服务开支的来源很难保证这些公共服务的有效提供。开征信息税所产生的收入、支出和调节等作用会产生一定的政策效应,如提高证券市场信息披露利益相关者对虚假信息披露问题进行治理参与的积极性,提高信息披露监管、信息披露规则建设和合法信息权利保障工作的财力支持,从而有利于证券市场信息披露质量、信息监管质量的提高,有利于证券市场有效性的提高和信息披露利益相关者合法权益的维护。     

How do trust and property security influence household contributions to public goods?: The case of the sloping land conversion program in China

Trust and property rights are generally considered to influence farmers' behavior regarding resource use and environmental management. Previous studies show that higher trust levels may enhance contributions to public goods. This paper investigates how trust and (land) property rights security influence the provision of one concrete public good: land protection through the Sloping Land Conservation Program in China. The analysis is based on household survey data from Ningxia Autonomous Region in China. From our questionnaire two trust factors are derived and distinguished, using factor analysis: general trust and kinship trust. Farm households are less likely to contribute to public goods when they perceive more secure land rights, but trust has mixed effects on public goods. The results show that general trust and kinship trust may rely on two opposite effects for influencing public goods provision. On the one hand, high levels of general trust may directly enhance people's willingness to provide contributions to public goods (by reduced likelihood to reconvert forest land) when farmers are aware of the positive environmental effects of the program, that's the public goods effect. On the other hand, general trust may also make it more likely that people invest more in their own private goods to pursue their own welfare (a more likely reconversion of forest land to arable land), that's the private goods effect. The final outcome depends on the size and direction of both effects. Compared to general trust, kinship trust is more inward-looking and self- or group-interested compared to more reciprocal general trust. Thus, unlike general trust, kinship trust may have no significant public goods effect on the provisioning of public goods.

Co-innovation in networks of resources — A case study in the Chinese exhibition industry

This work explores how network partners collaborate to innovate and innovate to collaborate and thereby achieve value. The innovation processes analyzed are within an IJV in the Chinese exhibition industry. The findings highlight that the IJV's development of a successful trade show resulted from effective co-innovation by partners which enabled the exploitation of opportunities in an industry characterized by rapid growth and continuing structural change. Partner co-innovation enabled evolving strategic and operational capabilities which has led to continued and growing market success. This co-innovation involved the targeted co-mingling of partner resources which creates value that motivated continued cooperation. The effectiveness of the partners' activities is evidenced by the growing size and prestige of their large-scale trade show as well as the expansion of the IJV into other endeavors. The paper concludes by considering the way these innovative processes can be applied in other contexts.     

我国合理市盈率与股市泡沫的实证分析

市盈率是被广泛用来测量股市泡沫风险的一个重要指标。本根据“股票的理论价格应该是未来各期红利的贴现之和”这一传统金融理论，导出用以衡量股市泡沫成分的基准——合理市盈率的计算方法。通过分析发现市盈率的合理值是一个动态值，据此测量出的上海A股市场泡沫成分自1993年以来呈明显下降趋势，说明我国股票市场上的投资日趋成熟，投资行为日趋理性。
