基于网络外部性的价值模块整合与兼容性选择

本文分析了价值模块的网络外部性特征，并基于网络外部性研究了价值模块整合过程中的兼容性选择和价格竞争行为。研究结果表明：当由进入厂商选择兼容度时，兼容性越高进入厂商的市场份额越大，并能够获得更高的市场价格；当由在位厂商选择兼容度时，兼容度增加将减少消费者的转移成本，使更多的模块需求商转向购买进入厂商的产品，减少了在位厂商的市场份额；当转移成本的兼容性敏感系数较低时，在位模块供应商能够获得更高的价格，而当转移成本对兼容性很敏感时，较高的兼容度将迫使在位模块供应商降低价格。价值模块的网络外部性加剧了模块供应商之间的竞争，进一步促进了价值模块整合和产业融合的过程。     

地方政府公共投资与区域经济增长的差异性分析

文章采用全国31个省、自治区和直辖市1995~2008年的面板数据,构建动态面板数据模型,考察了地方政府公共投资对区域经济增长的影响。研究表明,1995年以来我国地方政府公共投资总体上推动了区域经济增长,但不同公共投资项目的拉动效应在区域间存在着较大差异。     

我国地方政府债务风险研究——从资产负债表角度

以国内外相关文献为基础,结合我国地方政府债务的内涵,编制我国地方政府的资产负债表,并通过净资产、资产负债率、债务负担率、KMV 等的分析,对我国地方政府债务的风险进行分析,认为目前我国地方政府债务的风险很小,总体可控,并提出了改善我国地方政府债务风险的建议。     

本地偏好、投资者情绪与股票收益率:来自网络论坛的经验证据

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。     

地方政府债务、金融营商环境与实体企业融资约束

文章基于“财政金融关联”视角,利用2015至2020年省级层面的面板数据,实证检验了地方政府债务、金融营商环境与实体企业融资约束三者间的作用效果。研究结果表明：地方政府债务与企业融资约束存在正向推高关系,而良好的金融营商环境对实体企业融资约束存在负向抑制关系;异质性检验显示,地方政府债务对民营实体企业、中西部实体企业融资约束的推高作用更强;交互效应结果显示,金融营商环境的优化能有效缓解地方政府债务对实体企业融资约束的推高作用。因此,提出改善地区金融营商环境、对差异化企业性质实施优惠帮扶政策以及严控地方政府隐性债务增量是缓解实体企业融资困境,促进地区经济平稳发展的重要措施。     

城市集聚经济微观机制及其超越:从劳动分工到知识分工

本文在区分集聚机制与集聚效应、劳动分工与知识分工、成本外部性与技术外部性的基础上,使用统一的分析框架解释了城市集聚经济的发生机制,特别是将知识创造、知识溢出和知识积累结合起来,分析了知识分工与技术外部性促进城市集聚经济的发生机制。知识分工通过协作机制、结构匹配机制和循环累积机制促进知识的创造和积累,交流外部性条件下技术外部性的创新集聚效应和动态累积效应实现了知识在更大空间范围内的低成本使用,二者共同促进了城市收益递增。     

Cashlessness and scalable multi-pay practices: Capturing the everyday financial transactions in local contexts

While macro-level volume growth in India's move towards cashless payment systems is captured relentlessly, most often what gets ignored is a realization that everyday financial transactional practices are socially and culturally embedded in the local contexts. This paper drawn from an anthropological ethnography explores how people use and hierarchically order different payment systems in their everyday financial transactions for products and services. It explores how aspects such as trust, economic and social values, demographic differentials and scalable multi-pay practices influence such ordering and usage of the payment systems within their everyday local contexts.     

Accounting change and value creation in public services—Do relational archetypes make a difference in improving public service performance?

Evidence points out that the outcome of accounting change in local governments is not simply a matter of ‘corporate’ resource investments and change management activities to accounting system replacement. This paper examines the link between such corporate-level interventions and the patterns of value creation at street-level. It emphasizes a resource- and capability-driven approach to explore processes and consequences of an ‘embedded agency’-effect assigned to the street-level rationale of public service improvement. Considering a logic chain of cause-and-effect sequences, the data analysis provides evidence that corporate and street-level interventions are unique dimensions to signify the multiple patterns of accounting change in local governments. The supplementary effect of cross-functional relationships is also distinguished, considering the relational archetype as a mechanism to explain the emerging outcome state. Recognizing the distinction and the sequential effects of relational archetypes induces a refined typology of accounting change according to its processes and outcomes in local governments. The analysis is based on a comparative case study design to explore accrual accounting introduction in six German municipalities.     

A ‘panoptical’ or ‘synoptical’ approach to monitoring performance? Local public services in England and the widening accountability gap

This article highlights how recent reforms to the auditing and assessment of local public services in England suggest there will be a shift from panoptical to ‘synoptical’ monitoring approaches. This is because the UK Government has abolished its centralised monitoring regime and instead required local authorities to publish a range of financial and performance datasets online, ostensibly so that citizens can hold organisations to account directly. However, the complexity and raw nature of these data, along with the sidelining of professional auditors, will result in most citizens being either unable or unwilling to undertake this task. As such, the proposed ‘synoptical’ approach will not materialise. Indeed, other legislative changes will mean that outsourcing firms effectively become the new, unaccountable observers of local public sector bodies within an enduring panoptical system. In many cases these companies will then assume responsibility for delivering the same services that they have assessed.     

Local fiscal distress and investment efficiency of local SOEs

In this paper, we use A-share listed firms between 2002 and 2010 to investigate the relationship between local fiscal distress and the investment efficiency of local SOEs, along with the effect of corporate tax payments on this relationship. We find a positive relationship between the extent of local SOEs' overinvestment and the fiscal distress of the corresponding local government where the enterprise and this relationship become stronger for firms that pay fewer taxes. The pattern of underinvestment among local SOEs was in contrast,and these relationships do not exist for non-SOEs or central SOEs. Moreover,we find that expanding a firm's investment scale leads to an increase in total taxes paid, including income and turnover taxes, which further result in more local fiscal revenue. Overall, we conclude that local governments have an incentive to increase fiscal revenue when faced with fiscal distress by raising the investment scale of local SOEs and that the incentives and effects of such interventions appear to be stronger among firms that contribute less to local fiscal revenue.ó 2013 Production and hosting by Elsevier B.V. on behalf of China Journal of Accounting Research.
