Electrification and energy productivity

Energy productivity is crucial for sustainable development. We use cointegration analyses to investigate the effect of electricity on energy productivity in Swedish industry from 1930 to 1990. Electricity augmented energy productivity in those industrial branches that used electricity for multiple purposes. This productivity effect goes beyond “book-keeping effects,” i. e. it is not only the result of electricity being produced in one sector (taking the energy transformation losses) and consumed in another (receiving the benefits).     

The effects of mergers and acquisitions on the firm size distribution

This paper provides new empirical evidence on the effects of mergers and acquisitions (M&As) on the shape of the firm size distribution, by using data of the population of manufacturing firms in the Netherlands. Our analysis shows that M&As do not affect the size distribution when we consider the entire population of firms. When we focus on the firms involved in an M&A event, we observe a shift of the firm size distribution towards larger sizes. Firm size distribution becomes more concentrated around the mean, less skewed to the right hand side, and thinner at the tails as a whole. The shift toward higher sizes due to M&A is not uniform but affects firms of different sizes in different ways. While the number of firms in the lower tail decreased, the number of firms in the central size classes increased substantially and outweighed the increase in the number (and mean size) of firms in the upper tail of the distribution (consequently the overall market concentration measured by the Herfindahl index declines). M&As lead to a departure from log-normality of the firm size distribution, suggesting that external growth does not follow Gibrat’s law. Our counterfactual analysis highlights that only internal growth does not affect the shape of the size distribution of firms. On the contrary, it suggests that the change in the size distribution is almost entirely due to the external growth of the firms.

The co-evolution of business incubation and national innovation systems in Taiwan

Incubation has already proven to be of great value in promoting small and medium enterprise (SME) entrepreneurship activities and technological development in developed and developing countries. Incubation not only provides a diversified and integrated service for entrepreneurial ventures but also contributes upward to regional and national innovation and economic growth. Building upon the logic of co-evolution theory, this paper argues that incubation acts at the meso-level as a critical interface between macro-innovation systems and micro-business ventures. These multi-directional coupling elements in innovation ecology co-evolve to achieve collective interests and excellence, which in turn may stimulate technological development and social change. Important processes/mechanisms, including a policy kit and action, strategic networking, supportive associations, knowledge and intellectual capital management, among others, are discussed. Drawing on the national innovation system (NIS) and business incubation (BI) experience in Taiwan, we discuss the future prospects of incubation and innovation policies, including industrializing and globalizing incubation activities and virtual business incubation.     

河南省旅游产业集群构建

通过对河南省旅游产业集群的现状研究,发现其旅游产业集群的实力较弱,空间发展不平衡,效应低,旅游核心吸引物缺乏竞争力,旅游产业链条上还存在瓶颈和薄弱环节,各行业间尚未形成有机的产业联系,地区间尚未建立良性产业互动关系.河南省旅游产业集群的构建需要在地域空间上进行旅游各要素层的整合并进行区域关系网络和区域市场网络的构建得以实现.

基于实力积累的传统产业集群创新策略动态演化过程研究

有关传统产业集群的创新策略问题已成为理论界和实业界普遍关注的一个重要的论题,但是当前的研究多数是对某一种创新模式进行分析,而事实上,随着集群企业实力的不断增加,其创新策略的选择会发生相应的变化。通过对传统产业集群实力积累过程中创新策略动态演化规律的探讨,为传统产业集群的发展战略和政策设计提供参考。     

区域产业集群形成与发展的GERT网络研究

运用随机网络理论,构建了区域产业集群形成与发展的GERT网络模型,提出了区域产业集群形成与发展的“夭折”概率与“成熟”概率两个概念,并以高科技产业集群为例求解。在此基础上,研究政府在产业集群的不同阶段给予支持时,各种方案对产业集群形成与发展的作用效果。产业集群“成熟”概率的变化,说明了政府在产业集群发展的初期给予支持是最优的选择,进而说明了政府对产业集群支持的必要性以及支持方案的选择效果。
