研发模式对制造业企业创新绩效的影响

将企业研发模式分为自主研发、合作研发和双重研发三种，使用世界银行对中国制造业企业的调查数据，通过倾向得分匹配方法探究不同研发模式对企业创新绩效的作用效果及其在异质性企业中的差异情况。全样本研究结果表明：企业双重研发对创新绩效的激励效果最好，合作研发的激励效果次之，自主研发的激励效果最弱。企业异质性研究结果显示：自主研发对高成长性企业创新绩效的激励效果最显著，合作研发对低成长性企业和小微企业的激励效果最显著；对于无融资约束的企业，双重研发模式是提升创新绩效的最佳选择，但是对有融资约束的企业，其提升效果最弱。     

税收优惠影响企业创新产出的多元机制研究——来自中国软件与集成电路产业的证据

创新政策一直是激励企业创新的重要手段，其中税收优惠政策是一种具有市场导向性的激励政策，对企业创新具有良好的促进作用，但是政策对企业产生激励作用的原因尚不清晰。选取对我国技术突破有重要作用的软件与集成电路企业，采用2006-2018年中国A股上市公司数据，聚焦2011年国家对软件与集成电路行业的两个税收优惠政策，运用双重差分法对企业创新产出影响进行实证研究。结果发现：税收优惠政策对发明专利申请有显著促进作用，而对非发明专利申请无显著影响。融资约束、企业避税行为等是税收激励政策发挥作用的主要渠道。另外，税收优惠政策对不同规模、产权和区域企业有不同影响，税收优惠政策对大型企业、国有企业以及中西部地区企业创新产出促进作用更大。从税收优惠政策长期影响看，该政策对专利申请的影响存在时滞性，而发明专利申请在政策发生当年就显著增加。研究结论可为明晰税收优惠政策、融资约束与企业创新产出间关系提供有益启示。     

网络嵌入特征与研发经历对通讯企业预研阶段研发者选择的影响

预研关系到企业在未来行业发展中的竞争优势，但以往相关研究多集中于国防军工企业，对一般民用企业研究较少。从研发者嵌入的网络结构与其自身属性特征两个角度出发，验证通讯企业在3G到4G技术跨越过程中选择预研研发者的影响因素，给出中介中心度、自我中心网结构洞、研发经历3个方面的假设。通过稀有事件logistic回归分析发现，自我中心网中的结构洞个数越多、以往研发技术经历越丰富，研发者越可能被选拔进入企业预研活动。研究结论具有较高的应用价值，可为企业预研中人力资源管理提供决策依据。     

锚企业与科技新城共生模式研究:以阿里巴巴和杭州未来科技城为例

以阿里巴巴和杭州未来科技城为例，采用Logistic模型探讨锚企业与科技新城共生模式，结果表明：总体而言，阿里巴巴和未来科技城属于互利共生模式，阿里巴巴成长会促进未来科技城发展，而未来科技城发展也会反哺阿里巴巴的成长。2013-2016年两者共生系数之间的差值不断缩小，表明阿里巴巴和杭州未来科技城的共生模式从偏利共生转向互利共生。     

焦点企业知识存量对联盟组合分裂断层的影响：知识转移效率的中介作用

运用断层理论，从知识获取和关系治理角度，分析焦点企业知识存量如何影响联盟组合分裂断层及分裂断层形成机理。基于焦点企业知识存量、分裂断层、知识转移效率、情景嵌入性之间的关系理论模型框架，认为焦点企业知识存量能够影响联盟组合分裂断层，其中，知识转移效率在这一过程中发挥中介效应，情景嵌入性发挥调节效应。结果发现：焦点企业知识存量与分裂断层之间存在显著负相关关系；知识转移效率能够部分中介焦点企业知识存量与分裂断层之间的关系；情景嵌入性能够正向调节焦点企业知识存量与知识转移效率之间的关系。     

On post-IPO stock price performance: A comparative analysis of RLBOs and IPOs

This is the first study to examine the post-IPO stock price performance by differentiating between IPOs and three types of RLBOs (i.e. public-to-private (or re-IPOs), division-to-private, and private-to-private deals). We document that public-to-private RLBOs outperform their industry rivals, IPOs, mature firms in comparable industries, and a propensity-score matched control group for up to five years post-offering. Further, we document that, within RLBOs, public-to-private RLBOs, outperform private-to-private and division-to-private RLBOs. We also find support for the underwriter signaling effect for public-to-private RLBOs. Our analysis identifies for the first time what private period restructuring activities contribute to superior post-re-IPO stock price performance. Further, the beneficial effects of private period restructurings are enhanced for deals associated with prestigious underwriters. Our findings suggest that first IPOs and re-IPOs differ substantially in term of post-offer performance, the impact of prestigious underwriters on performance, and performance over time.     

Judgment aggregation in search for the truth

We analyze the problem of aggregating judgments over multiple issues from the perspective of whether aggregate judgments manage to efficiently use all voters' private information. While new in judgment aggregation theory, this perspective is familiar in a different body of literature about voting between two alternatives where voters' disagreements stem from conflicts of information rather than of interest. Combining the two bodies of literature, we consider a simple judgment aggregation problem and model the private information underlying voters' judgments. Assuming that voters share a preference for true collective judgments, we analyze the resulting strategic incentives and determine which voting rules efficiently use all private information. We find that in certain, but not all cases a quota rule should be used, which decides on each issue according to whether the proportion of ‘yes’ votes exceeds a particular quota.     

Non-farm entrepreneurship in rural sub-Saharan Africa: New empirical evidence

We report on the prevalence and patterns of non-farm enterprises in six sub-Saharan African countries, and study their performance in terms of labor productivity, survival and exit, using the World Bank’s Living Standards Measurement Study - Integrated Surveys on Agriculture (LSMS-ISA). Rural households operate enterprises due to both push and pull factors and tend to do so predominantly in easy-to-enter activities, such as sales and trade, rather than in activities that require higher starting costs, such as transport services, or educational investment, such as professional services. Labor productivity differs widely: rural and female-headed enterprises, those located further away from population centers, and businesses that operate intermittently have lower levels of labor productivity compared to urban and male-owned enterprises, or enterprises that operate throughout the year. Finally, rural enterprises exit the market primarily due to a lack of profitability or finance, and due to idiosyncratic shocks.     

Auction fever: Rising revenue in second-price auction formats

The prevalent term “auction fever” visualizes that ascending auctions – inconsistent with theory – are likely to provoke higher bids than one-shot auctions. To explore and isolate causes of auction fever experimentally, we design four different strategy-proof auction formats and order these according to expected rising bids based on pseudo-endowment effect arguments (psychological ownership and disparity between willingness to pay and willingness to accept). Observed revenues in the experiment in the four formats rank as expected if bidders have private uncertain values (the private information of a bidder is the distribution of her value). A control treatment supports our view that the traditional private certain values approach prevents auction fever in the laboratory. Another control treatment with a procurement auction relates the auction fever bids to bids in a one-shot auction with real endowments. We conclude that, when bidders are uncertain about their valuations, auctions that foster pseudo-endowment may raise bids and revenues.     

论营改增对交通运输企业利润的影响——以中海发展股份公司为例

2016年5月1日,营改增将进行最后四个行业的全面试点,从2012年首先开始于交通运输业等行业的营改增,已经进入了收关之际.从历经4年多的试点结果来看,从2012年试点到2015年底,"营改增"已经累计减税5000多亿元,结构性减税效果明显.交通运输业作为我国重要的行业,又是第一批试点行业,虽然交通运输业营改增后,流转税负呈下降的趋势,但对交通运输行业的利润影响是否是正向的还需要科学的研究,因此,本文以中海发展股份公司为例,分析营改增后影响交通运输业利润的变化及因素,并给出相应的建议.
