钢铁工业不是"夕阳工业"

由于全球钢铁生产能力过剩,产品价格下降,企业获利减少,因此,有人提出钢铁工业已成为"夕阳工业".本文从三方面说明钢铁工业不存在"夕阳工业"的命题.首先,钢铁仍是经济发展中不可替代的基础材料;第二,世界钢材消耗量,尤其是发展中国家的消耗量有所增长;第三,我国作为产钢大国、消费大国的市场空间很大.     

港口货流预测分析及软件技术

物流技术随着电子商务的崛起已逐渐成为新经济研究的焦点。随着入世的临近及入世的实现,作为物流中心枢纽的港口,其货（物）流将会发生极大的变化,无论是货种、流向还是货物公司及运输方式、运输始发地等,都会有较大的改变,迫切需要行之有效的预测方法及软件。基于灰色理论的预测方法较传统的统计预测方法有较大的不同,它不需要多数据统计的样本,是解决少数据不确定系统预测的有效方法,对我国新港多,港口统计数据不稳定不全面等情况尤为合适。本预测分析软件运用最新的数据库与界面技术,使得预测快捷、直观、界面友好。

Information interaction capabilities: conceptualisation and instrument development

The twenty-first century has seen the rise of a new wave of technological change and industrial revolution. The next-generation Information Technology (IT) is radically shifting the core competence of corporation, meaning of value creation, and sources of a competitive advantage. In this situation, it is imperative for firms to build a new core competence. Based on the resource-based theory, this paper describes the competence of firms in the information interaction area, frames the concept and classification systems of information interaction capabilities (IICs), develops the scale of IICs, and tests the relationship between IICs and competitive advantages using empirical data in China. In short, the paper identifies that IICs are an important competence in the environment of the next-generation IT. Conceptualising IICs provides a foundation for bridging information interaction and strategy research. IICs provide a holistic approach to building the new core competence and achieving competitive advantages.     

The impact of dual network structure on firm performance: the moderating effect of innovation strategy

ABSTRACT

Firm innovation is embedded in a collaboration network among researchers and a knowledge network composed of knowledge elements; the two networks are decoupled. Guided by social network theory, this study puts forward the definition and the classification of firm dual network structure, probes into the influence of dual network structure on firm performance, and explores the alignment between innovation strategy and firm dual network structure. We conduct an empirical study of 183 listed companies in China from 2004 to 2018. It is found that the four types of dual network structure all have positive impacts on firm performance, and the impact of a collaboration network is slightly higher than that of a knowledge network. Besides, innovation strategy plays a positive moderating role in the relationship between dual network structure and firm performance. Our findings provide new ideas for firms to identify and optimise knowledge and collaboration network structures and match them with innovation strategy to improve performance.     

技术权力、组织间信任影响领导行为的跨案例研究

在技术创新网络中,非对称的技术权力和不同程度的组织间信任引致了核心企业对合作企业采取不同领导行为。从心理定位视角出发,基于技术权力和组织间信任两个变量提出核心企业的4种领导行为——技术锁定、技术防御、技术扶持与技术标准,通过跨案例研究,分析论证了这4种领导行为,并对合作过程中核心企业的领导行为进行了科学解释,以帮助合作企业科学预测领导行为,进而提高运行绩效和网络地位。     

2018 KLEIN LECTURE: INDIVIDUAL AND AGGREGATE LABOR SUPPLY IN HETEROGENEOUS AGENT ECONOMIES WITH INTENSIVE AND EXTENSIVE MARGINS

We study business cycle fluctuations in heterogeneous agent general equilibrium models featuring intensive and extensive margins of labor supply. A nonlinear mapping from time devoted to work to labor services generates operative extensive and intensive margins. Our model captures the salient features of the empirical distribution of hours worked, including how individuals transit within this distribution. We study how various specifications influence labor supply responses to aggregate technology shocks and find that abstracting from intensive margin adjustment can have large effects on the volatility of aggregate hours even if fluctuations along the intensive margin are small.     

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.
