基于专利信息的产业技术竞争优势测度模型构建与实证研究

提出产业技术竞争优势的概念，并探讨其"规模-质量-价值"三维模型和测度指标体系；构建产业技术竞争优势指数，利用熵值法设置权重，采用合成指数法计算产业技术竞争优势指数。以世界生物医药产业主要国家（中、美、德、日）1996-2016年样本数据进行实证研究。结果表明：中国生物医药产业技术竞争优势指数及分指数总体保持上升趋势，其中规模指数增长较快，价值指数次之，质量指数发展居于末位；美国、日本和德国竞争优势指数相近，均具有较强的竞争优势；中国产业技术竞争能力处于劣势地位，规模维度方面中国与其它三国差距较小，价值维度差距次之，质量维度差距较大。     

家族控制与企业创新投入

家族企业对社会情感财富目标的追求是其区别于非家族企业的重要特性，社会情感财富目标与企业经济利益间冲突对企业R&D投入的影响不容忽视。以社会情感财富为理论基础，基于573家上市家族企业2011-2015年的面板数据，分析受市场化程度影响时，家族涉入情境下信息透明度对企业R&D投入的影响。结果显示：信息透明度可以有效缓解信息不对称和代理冲突，促进企业R&D投入；家族控制对R&D投入有消极影响；当企业信息透明度较高时，会抑制家族所有者为个人谋取私利的动机，进而增强其对企业R&D投资的积极作用。在市场化程度更高、产权保护力度较大的地区，信息透明度会缓解家族控制权对R&D投入的消极作用。     

同群效应与公司研发*——来自中国的证据

本文研究了“同群公司”的研发支出对公司自身研发行为的影响。研究发现，同群公司研发支出越多，公司自身研发支出也越多。进一步研究发现，在公司与同群公司地理距离较近或同群公司分析师覆盖程度较高情况下，同群公司研发支出与公司自身研发支出的正相关关系更强。此外，同群公司研发支出会提高公司自身研发支出与未来业绩的正相关程度。研究表明，公司会学习同群公司的研发决策，进而改变其自身研发决策，呈现显著的研发支出同群效应；且公司信息解读成本较低时，研发支出同群效应更为显著。本文不仅丰富了关于研发支出影响因素的研究，还拓展了对研发溢出效应的研究。本文的研究结论对公司制定研发决策具有重要指导意义。     

Economic interpretations of DEA

Research on productive efficiency at the firm level has developed as an important and active strand of research the last decades, both within operations research, management science and economics. Two apparently different definitions of efficiency are examined, but it is shown that when both estimation methods are based on solving linear programming problems the definitions of efficiency are identical. The purpose of the paper is to give the basic ideas of efficiency analyses using DEA as a tool for researchers not so familiar with efficiency analysis and DEA. The concept of shadow prices is given special attention.     

智能生产与服务网络下新型产业创新平台运行模式研究

在智能生产与服务网络化背景下，传统产业创新平台技术含量低、创新积极性不高、持续升级能力弱、成果转化效率低等矛盾日益凸显。针对该问题，提出了智能生产与服务网络下的新型产业创新平台运行模式。首先从科技支撑、智能生产与服务组织、感知与信息传输、基础设施和平台规制角度研究其组织结构，并从个性化定制、模块化集成和全程价值链供给角度研究其功能结构；然后从协同创新、导向、风险和产业生态进化角度研究其保障机制；最后从市场化角度研究其运行路径。通过研究智能生产与服务网络下的新型产业创新平台运行模式，为实施传统产业高端化、推动行业进步、促进经济发展提供参考与借鉴。     

Mandatory IFRS adoption and management forecasts: The impact of enforcement changes

We examine how concurrent enforcement changes affect the positive relationship between mandatory IFRS adoption and firms’ voluntary disclosure. We show that the increase in the issuance of management forecasts after IFRS adoption is smaller for firms from IFRS-mandating countries with concurrent enforcement changes than for those from countries without such changes. We find no difference in the increase of forecast informativeness between firms from IFRS-mandating countries without concurrent enforcement changes and firms from non-IFRS-mandating countries; however, firms domiciled in IFRS-mandating countries with concurrent enforcement changes exhibit a significantly smaller increase in forecast informativeness. Our findings suggest that better IFRS enforcement distinctly weakens (strengthens) the positive effect of IFRS adoption on voluntary (mandatory) disclosure.     

Why you should use high frequency data to test the impact of exchange rate on trade

This study suggests that testing the impact of exchange rate on trade should be done using high-frequency data. Using different data frequencies for identical periods and specifications between the US and Canada, we show that low-frequency data might suppress and distort the evidence of the impact of exchange rate on trade in the short run and the long run.     

The Effect of Foreign Entry Regulation on Downstream Productivity: Microeconomic Evidence from China*

We examine the cross‐industry influence of foreign entry regulation (based on a novel measure) on the productivity outcomes of downstream firms through input–output linkages in China. In contrast to the significant liberalization of the manufacturing sector, restrictions on the service sector remained stringent over the period 1997–2007. We find a powerful depressant effect of foreign entry barriers imposed on the upstream manufacturing and service industries on the productivity of downstream manufacturers, and this effect depends on a number of industry‐ and firm‐specific features. Our research calls for further investment liberalization (particularly in the service sector) in China.     

企业主流与新流创新演进机理研究

激烈的市场竞争使人们意识到，企业既需要维持创新发展优势而抢占主流市场，又需要创造新的企业发展优势而赢取未来主流市场。着眼于这一关键任务，实现主流与新流创新演进成为企业持续发展的重点。因此，基于生物进化理论、企业进化理论和企业DNA理论，提出主流与新流创新演进经过了生成、变异、选择、协同阶段。深入研究主流与新流创新的生成、变异、选择、协同机理，并与企业创新发展实践相结合，为企业未来主流创新提供具体路径指导。     

Bank Competition and its Determinants: Evidence from Indian Banking

Abstract

This paper measures the degree of bank competition in India using a sample of 70 commercial banks over the period 1996–2016. To assess the degree of competition, we estimate the market power of each bank in our sample employing three nonstructural measures: the Lerner index, the adjusted Lerner index, and the Boone indicator. Bank-wise and year-wise estimates of the marginal cost required in all these measures are obtained using the semi-parametric method. The paper further attempts to undertake a comprehensive assessment of competition in Indian banking and identifies various bank-specific, macroeconomic, structural, and contestability indicators, which are supposed to explain level and variation of the degree of competition over time. Empirical findings reveal that public-sector banks in India exercise a relatively higher degree of bank competition compared to private and foreign-sector banks. However, aggregate results support that the Indian banking system is competitive in general. Unlike the structure-conduct-performance paradigm, which advocates that a concentrated banking system impairs competitiveness, our findings reveal that concentration measures hardly exert any effect on bank competition. Rather, contestability measures play a significant role in the determination of bank competition.
