交通基础设施建设是否影响了区域创新

基于2000-2018年中国内地省级面板数据，以自主创新和模仿创新两种模式为切入点，构建中介效应模型，实证检验交通基础设施建设对区域创新的影响效应。研究表明：交通基础设施建设显著促进了自主创新，抑制了模仿创新。交通基础设施建设主要通过扩大人力资本积累、促进经济增长、带动产业升级和减轻环境治理负担等路径间接影响区域创新。此外，公路建设对区域创新的影响力远小于铁路建设，西部地区交通基础设施建设对区域创新的影响力远大于东、中部地区。     

Hong Kong's entrepreneurship: behaviours and determinants

It is widely known that Hong Kong's economic success is to a large extent attributed to its dynamic entrepreneurs. However, economic studies on Hong Kong's style of entrepreneurship are few. This paper attempts to throw light on this issue. It argues that Hong Kong is an entrepreneurial society. A unique feature of Hong Kong's style of entrepreneurship lies in its ability to conduct ordinary, rather than extraordinary, discovery. Through the use of guerrilla business strategy, imitation and regional arbitrageurship, entrepreneurial firms in Hong Kong are able to exploit narrow profit margins and to survive global competition. Moreover, the cultural, economic and political environments of Hong Kong are found to be favourable in incubating adaptive entrepreneurship. This paper concludes that, although Hong Kong's style of entrepreneurship emerges out of its unique environments, Hong Kong's experience can be useful to other developing economies. The critical issue is whether latecomer countries can successfully develop adaptive entrepreneurship compatible with their backgrounds so as to exploit international market opportunities.     

Actions influenced by a social network

A simple framework is presented in which, each period, each of N individuals chooses among K alternatives. Individual actions are interrelated through a social network which arrays the strength of influence of each person on each other person. Emphasis is on the role of the network. The framework accommodates a variety of particular contexts, suggests theorems, and unifies a sizable part of the fragmented literature on network interaction.     

Industry dynamics with knowledge-based competition: a computational study of entry and exit patterns

I propose a computational model of industry evolution capable of matching many stylized facts. It views the firm as a myopic but adaptive entity whose survival depends on its ability to perform various activities with greater efficiency than its rivals. In this model, the shakeout pattern arises naturally in the early stage of industrial development. I provide a full comparative dynamics analysis of how various industry-specific factors determine the numbers and the rates of entries and exits over time as well as the ages of the exiting firms. An earlier version of this paper was circulated and presented under the title, “Non-Equilibrium Industry Dynamics with Knowledge-Based Competition: An Agent-Based Computational Model.” I would like to thank the two anonymous referees, Jason Barr, Ed Bell, Jon Harford, Joe Harrington, Bill Kosteas, Edward Nell, and the conference participants at the EEA-2007 Meetings (New York, NY) as well as the 2007 International System Dynamics Conference (Boston, MA) for their helpful comments and suggestions.

Revealing the depth of reasoning in <Emphasis Type="Italic">p</Emphasis>-beauty contest games

The aim of this study is to evaluate the impact of information on levels of reasoning on individuals' choices in p-beauty contest games. In the baseline design, subjects received information only on the average and target values from the previous period. In the alternative design, the winner(s) explained in a short message (30 words maximum) what reasoning he/she applied in selecting the target value and then stopped playing. The winner's message, the winning number, the target and average values were then displayed on all computer screens. The results show that non-winning players imitate the level of rationality of winners, and a significant proportion of the population adopt strategies which are best responses to other imitators' behaviour rather than to the average level of rationality. Both the imitative strategies and the best responses to the imitative strategies stimulate a strong acceleration of the learning process.

技术差距、知识产权保护与后发国技术进步

已有研究知识产权保护的国际技术扩散模型都假定后发国只进行模仿，不进行自主创新，并且没有考虑技术差距和模仿能力对知识产权保护制度安排的影响。本文基于中间产品种类扩张的内生增长模型，考虑了知识产权保护在鼓励自主创新和模仿国外技术两难中的权衡，认为知识产权保护对后发国技术进步的影响取决于技术差距和对国外技术的模仿能力。并据此分析了我国相关政策的选择。     

Innovation, imitation, and new product performance: The case of China

This paper compares the effects of innovation and imitation strategies on new product performance and examines their contingency across different market conditions in China. The empirical results from a cross-industry survey show that, compared with an imitation strategy, an innovation strategy leads to better new product performance. Furthermore, the benefits of an innovation strategy over an imitation strategy become stronger as market demand is increasingly uncertain, technology changes rapidly, and competition intensifies. The author compares the findings with the predictions put forward in previous Western-based literature and discusses the implications of the findings in light of China's unique market characteristics.     

基于多目标规划的寿险公司资产负债管理

资产负债管理是保险公司管理的核心内容之一,其所要实现的目标很多,其中某些目标之间是具有矛盾性的。本文针对寿险公司资产负债管理存在的众多冲突目标问题,建立了一个多目标资产负债管理模型,以帮助寿险公司实现资产配置和负债配置的风险最小化目标、利润最大化目标和公司价值最大化目标。算例分析发现,基于多目标规划的资产负债管理模型能够同时实现不同的目标,改善寿险公司的管理效果,而且该模型具有稳定性。     

转型环境下创业战略与新创企业竞争优势关系研究

创新战略有利于企业构建新的价值链，模仿战略是对市场已有价值链的补充，现有研究主要关注创新战略，对模仿战略关注不足，实践中很多新创企业通过模仿战略实现创业成功。特别地，中国转型环境下制度不完善造成的不良竞争环境会制约创新战略，促进模仿战略。然而，实践中这两种战略对新创企业均存在积极影响，选择创新战略还是模仿战略事关新创企业创业成败。考察技术、市场环境和制度环境特征，剖析不同技术和市场环境下不良竞争对创新战略和模仿战略的调节作用。利用153份新创企业样本研究发现：创新战略和模仿战略均有利于竞争优势，但不同环境特征下作用效果存在差异。不良竞争对模仿战略的影响与技术、市场环境特征不相关；对创新战略的影响与技术、市场环境特征相关。创新战略和模仿战略并不存在孰优孰劣，是一定约束条件下新创企业战略决策的结果。     

New Evidence on Determinants of Intellectual Property Litigation: A Market-Based Approach

Abstract

We contribute to the economic literature on patent litigation by taking a new perspective. In the past, scholars mostly focused on specific litigation cases at the patent level and related technological characteristics to the event of litigation. However, observing intellectual property (IP) disputes suggests that not only technological characteristics may trigger litigation suits, but also the market positions of firms, and that firms dispute not only over single patents but often over portfolios. This paper examines the occurrence of IP litigation cases in Belgian firms using the 2013 Community Innovation Survey with supplemental information on IP litigation and patent portfolios. The rich survey information regarding firms’ general innovation strategies enables us to introduce market-related variables such as sales with new products, as well as sales based mainly on imitation and incremental innovation. Our results indicate that when controlling for firms’ IP portfolios, the composition of sales in terms of innovation and imitation has additional explanatory power regarding litigation propensities. Firms with high sales from innovations are more likely to become plaintiffs in court. Contrastingly, firms with high sales from incremental innovation and imitation are more likely to become defendants in court and, moreover, are more likely to negotiate settlements outside of court.
