本文以投资者在东方财富网股吧针对创业板上市公司发表的90多万条帖子为研究对象,通过IP地址识别,构建本地关注指标;并利用计算机文本挖掘技术,提取网络发帖所体现的情绪倾向,构建投资者情绪指标。实证结果显示,本地关注对股票收益率的影响取决于投资者情绪,当投资者持积极情绪时,本地关注对股票收益率有显著的正向影响;当投资者持消极情绪时,该影响显著为负。在积极情绪和消极情绪下本地关注对股票交易量都有显著正向影响,但积极情绪下的影响程度比消极情绪下更大。此外,本地关注与投资者情绪的交叉效应在上市公司样本数量较多的北京、广东、江苏、上海、浙江这五个区域都存在,并与整体样本的特征基本一致,但在样本数量较少的其他区域并不完全一致。 相似文献

区域创新能力提升是我国加快建设创新型国家、实现高质量发展的现实需求。 本文通过构建涵盖资源依赖、制度安排与区域创新能力的理论模型分析其内在关系并提出假 说,运用2000-2016年全国30个省(区、市)的面板数据与空间杜宾模型,检验三者之间的影 响及空间溢出效应。研究结果表明:(1)资源依赖程度越高,越不利于本地区创新能力提升;(2)有效率的制度安排对区域创新能力有正向促进作用;(3)从空间溢出效应来看,本地区 资源依赖程度越高,越抑制周边地区区域创新能力提升,有效的制度安排能助推周边地区创新能力提高。 相似文献

过度自信程度不同的投资者因消息确认精度差异引起意见分歧,产生异质后验信念,导致投资者对股价高估或者低估。在此基础上,以盈余公告信息作为利好或利空消息,研究不同环境下异质后验信念对我国股票价格的影响。实证结果表明:不管在牛市还是在熊市环境下,异质后验信念均会对股价产生影响,当盈余公告为利好消息时,异质后验信念程度越高,当期股价被高估的程度越显著;当盈余公告为利空消息时,异质后验信念程度越高,当期股价被低估的程度越显著。此外,在盈余公告前投资者就对盈余消息作出了反映,但对好消息与坏消息的反映程度不同。 相似文献

Scenario planning in the public sector has significant differences from scenario planning in the corporate world. Scenario planning in the government not only tends to be focused on issues of higher complexity and significance to public policy, but also in comparison to people in the private business, public officials have fundamental psychological and institutional constraints in their scenario thinking. These constraints make it difficult for them to contemplate multiple ‘untidy’ futures and imagine the possibility of policy failure: skills which are essential for successful scenario projects. Based on specific characteristics of scenario planning in the Japanese government, this paper contributes on better understanding the challenges and strategic solutions in providing more successful scenario planning in the public sector. Specifically, this paper argues that possible solutions in overcoming these constraints may be to shake public bureaucrats out of their thinking by providing free and open venues of conversation and more importantly through ‘derailment’ exercises. 相似文献

In this paper, we examine the motivations for preparers in Greek non-listed companies to adopt International Financial Reporting Standards (IFRS). Previous literature has focused on listed companies and assessed the effect of IFRS on market efficiency to justify its adoption. Using data from a cross-sectional survey and from interviews with senior managers, our analysis indicates that the motivations to adopt IFRS in Greece are not primarily related to the technical competence of the standards. We draw insights from literature on institutional theory and hegemony based on the Selections from the Prison Notebooks of Gramsci, and show that the decision to comply with IFRS can also be motivated by coercive and hegemonic pressures, which are exerted by powerful institutional constituents as they interact with organisations’ strategic interests at the international and national level. The adoption of IFRS is driven predominantly by the pressures exerted by parent companies on their subsidiaries and by the legal requirements of the state, but also through borrowing and debt-contracting requirements as enforced by civil society actors, such as financial institutions. This mobilisation of power plays a pivotal role in supporting the establishment of IFRS among non-listed companies. 相似文献

This article investigates the effect of heterogeneous beliefs on firms’ mergers and acquisitions (M&A) decisions. Using data of China’s financial market, which is featured with great heterogeneity of belief, we find that heterogeneous beliefs are positively associated with the occurrence of M&A transactions, and firms with greater heterogeneous beliefs are more likely to pay the transactions with stock. Moreover, we show that government intervention, measured by state ownership, weakens the effect of heterogeneous beliefs on firms’ M&A decisions. 相似文献

We offer new theory and evidence regarding the effects of pro-market institutions on outward foreign direct investment (FDI) of emerging market firms (EMFs). Drawing on the logic of institutional arbitrage, we integrate the escapism and exploitation mechanisms of EMF internationalization into a unified theoretical context. We propose an inverted U-shaped relationship between host market-supporting institutions (MSI) and the investment scale of an EMF’s FDI project in the country, showing an escape-driven upward slope for low-to-medium MSI levels and an exploitation-driven downward slope for medium-to-high MSI levels. We supplement this main argument with two boundary conditions: the alleviating effect of home market liberalization (HML) and the strengthening effect of home government subsidies (HGS), demonstrating the coexistence and variation of pro- and anti- market institutions in an emerging market. Using information on 1,450 FDI projects conducted by 288 Chinese listed firms in 116 host countries, we obtain supportive evidence for the predicted relationships between the three institutional forces. This study enriches the literatures on institutional arbitrage and pro-market institutions with evidence from EMFs. 相似文献

Many natural resource management researchers have focused either on institutional design and evaluation or on livelihood outcomes per se without explicitly acknowledging and rigorously examining linkages between the two. Thus, a major gap in the current literature on co-management institutional arrangements is the extent to which co-management has strengthened the livelihoods of poor forest-dependent communities. This gap is addressed in this paper by developing and testing an argument that well-designed co-management arrangements have strengthened the livelihood outcomes of poor forest-dependent communities in a Kenyan case study. The hybrid analytical framework developed for this analysis situates Ostrom's (1990) design criteria for co-management institutions in the broader context of the Sustainable Livelihood Framework. It then uses this analytical framework to evaluate the Arabuko-Sokoke Forest Reserve (ASFR) co-management initiative in Kenya, based on a three-step process. First, the paper provides an overview of current institutional arrangements for governance of the ASFR co-management regime. Second, it evaluates the extent to which these governance arrangements can be characterized as devolved collaborative governance, informed by Ostrom's (1990) design principles and; third, it evaluates the extent to which the livelihood outcomes of forest dependent communities that are participants in the co-management project have had their livelihoods strengthened as a result of the ASFR co-management governance arrangements. The paper demonstrates that the institutional arrangements for ASFR co-management are relatively nascent and emerging because the governance arrangements for the ASFR co-management project cannot be characterized as fully devolved de jure collaborative governance. Notwithstanding this, the findings reveal that participant forest-dependent communities in the co-management project had improved livelihoods compared to forest-dependent communities outside the co-management scheme. It is suggested that this is due to the de facto co-management arrangements. 相似文献
