油价不确定性与企业投资

本文利用2000-2015年中国宏观经济数据和1998-2007年中国工业企业调查数据,从宏观和微观两种视角考察了投资对油价不确定性冲击的反应。宏观研究发现,油价不确定性冲击不仅能够解释约12%的固定资产投资波动,而且还对固定资产投资具有短期抑制效应。在微观层面,本文采用基于异质性折旧率计算得到的企业投资,发现油价不确定性冲击在短期内对民营企业和外资企业投资也有抑制效应,但是对国有和集体企业的影响不显著,这一结论随着企业折旧率异质性的程度提高将变得更加明显。进一步分析发现,与非国有企业相比,国有和集体企业的投资行为具有明显的政策导向性,特别是在“十五计划”实施以后,国有和集体企业的投资密度比非国有企业高出约2.1%。这种政策导向性的存在,使得国有和集体企业的投资对油价不确定性冲击的反应并不显著。     

智力资本、向客户学习对创新的影响

以广州、北京、天津、台湾4个地区140家制造企业为研究样本,运用分层回归模型,从向客户学习的角度,对智力资本影响产品创新及工艺创新的作用机制进行实证分析。研究发现,向客户学习在智力资本影响创新的过程中发挥部分中介作用;当企业规模不同时,向客户学习在智力资本影响产品创新的过程中所发挥的作用存在差异,企业规模较大时,向客户学习在智力资本影响产品创新过程中发挥部分中介作用,企业规模较小时则发挥完全中介作用,但是向客户学习在智力资本影响工艺创新过程中所发挥的作用在不同企业规模下并没有显著差异,均发挥部分中介作用。     

知识网络演进视角下企业技术创新能力进化及政策建议

企业技术创新能力具有类生物进化的属性,基于该思想,以知识网络演进为背景,研究了知识网络对企业技术创新能力进化的作用,探讨了企业技术创新能力进化过程,进一步构建了企业创新能力进化的逻辑模型。研究发现,知识网络的循环演进通过知识获取、知识处理、知识共享和知识整合,促进企业技术创新能力不断进化。最后,分别从政策制定者角度和微观创新者角度,提出了促进企业技术创新能力进化的建议。     

技术创新能力生命周期与研发投入对企业绩效的影响

研发投入与企业绩效的关系一直备受国内外学者关注,但对该问题的研究并未得出一致结论。技术创新能力是高新技术企业内部能力的基础,不同技术创新能力水平下研发投入对企业绩效的影响存在显著差异。通过分析78家高科技上市公司2007-2013年面板数据,建立回归方程模型,探讨了在不同企业技术创新阶段研发投入与绩效的关系。实证研究表明,在成长期与成熟期,研发投入与绩效呈正向关系。其中,在成长期,该正向关系最显著;进入衰退期,二者之间不存在统计意义上的相关性。     

技术创新与企业IPO后绩效表现

企业技术创新一直以来都是学术界研究的热点,对企业生产经营、行业竞争以及发展战略发挥着重要作用。传统企业技术创新衡量方法研究在IPO后绩效表现方面存在不足。研究发现,企业IPO决策过程中IPO时机与特征可以反映其技术创新动机,进而可基于技术创新角度对企业IPO后绩效表现作出合理解释。通过构建技术创新评价指标,对比分析了技术创新企业与非技术创新企业在IPO后长期绩效表现的异同点。结果表明：①技术创新动机与企业IPO后财务绩效正相关,技术创新强的企业在后市仍能保持良好业绩;②技术创新企业的长期市场表现看涨,而非技术创新企业则呈现波动;③技术创新企业存活质量明显高于非技术创新企业。     

Learning from processing trade: Firm evidence from China

Processing export plays a significant role in international trade. In this paper, focusing on firm-level dynamics, we show that firms learn from their processing export experience to improve their subsequent ordinary export outcomes. Using transaction-level trade data and firm-level production data, we show that firms’ ordinary export performance, at both extensive and intensive margins, is enhanced by their own processing experience. Firms also export products with improved quality after engaging in processing exports of similar products. Furthermore, we investigate potential channels through which firms learn from processing experience. We find that firms potentially learn from processing experience to enhance production efficiency, to better understand how to improve product appeal to cater to specific markets, and to gain better and easier access to inputs. Moreover, we find that exporters benefit more from processing experience for larger markets with fiercer competition. Similarly, stronger learning effects are also observed when processing experience is associated with products that embody less diffused knowledge and are more differentiated. Also, firms learn more from processing experience when they are more actively engaged in processing imports. Lastly, we verify the economic significance and quantify the importance of these potential channels.     

社会情感财富对家族企业创业导向的影响

在将家族企业社会情感财富划分为家族控制、家族代际传承意愿、家族认同和家族社会资本4个维度的基础上,研究不同维度社会情感财富间关系及其对家族企业创业导向的影响与作用机制。结果发现：①家族控制对家族代际传承意愿、家族认同和家族社会资本具有显著正向影响;②家族控制对家族企业创业导向具有显著正向影响,家族代际传承意愿、家族认同、家族社会资本在家族控制与家族企业创业导向间起完全中介作用。     

家族企业创业导向与企业成长：社会情感财富与制度环境的调节作用

旨在研究家族企业创业导向对企业成长的影响,并探讨社会情感财富和制度环境在二者之间的调节作用。运用8个省份家族企业问卷调查数据进行分析检验,结果表明：①家族企业创业导向对企业成长具有显著正向影响;②社会情感财富不同对家族企业创业导向与企业成长关系的影响不同,家族控制正向调节家族企业创业导向与企业成长关系,家族代际传承意愿负向调节家族企业创业导向与企业成长关系,即随着家族控制意愿的增强或家族代际传承意愿的降低,家族企业创业导向对企业成长的影响增大;③制度环境正向调节家族企业创业导向与企业成长关系,即随着制度环境的改善,家族企业创业导向对企业成长的影响增大。     

Understanding the size and profitability of firms: The role of a biological factor

In a large sample of entrepreneurs, 2D:4D (second-to-fourth digit) ratio and managerial performance are studied. Entrepreneurs with lower ratio manage larger firms, manage larger firms when acquire control and experience faster average growth. Firms run by high prenatal testosterone entrepreneurs have lower profitability as measured by return on assets and return on sales. Prenatal testosterone is correlated with elicited measures of entrepreneurial skills, like work effort and optimism and the latter are correlated with firm size. This evidence suggests entrepreneurial ability has a biological component and is consistent with models of the size distribution of firms based on entrepreneurial ability.     

Who rides the tide of regionalization: Examining the effect of the China-ASEAN Free Trade Area on the exports of Chinese firms

This study draws on the institutional economics and the resource-based view to examine the impact of regional institutional changes on firm exports. Specifically, we utilize the establishment of the China-ASEAN Free Trade Area as our research context. Our difference-in-difference analysis of a four-year panel of 700 Chinese listed firms lends support to our arguments that (1) regional institutional changes aimed at increasing economic incentives for intraregional business exchanges will stimulate firm exports in the regional market and that (2) private firms, more technologically competent firms, and firms with richer regional exporting experience are affected more strongly by this institutional influence.
