Analysis of interregional industry linkage and economic distance in China: evidence from the mining industry

The mining industry is an important sector of the national economy, which provides essential support for energy and other resources for economic development. Industrial linkage and economic distance are two different concepts in measuring the correlationship of different industries, in this article, we apply the model that combines both of them to analyse the industries significantly influence the mining industry. We find that electricity and heating industry, and the mining industry itself from forward linkages have greatly influenced the mining industry, and the industries from backward linkages affect mining industry are changing with industrial economic transformation. We also find resources can flow across several regions only after 2007, which means the role of geographical factors limiting long-range transportation of resources is weakening after 2007. And we explain how resources flow among various regions during 1997 ~ 2007. Based on the findings above, policy implications from the empirical results obtained are discussed.     

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.

对现阶段中国长期护理保险产品的开发建议

卫生部调查数据显示：中国60岁以上老年人余寿中有2／3的时间带病生存,平均1／4左右的时间处于机体功能受损状态。2008年底,中国60岁以上人口总数达到1．49亿,医疗保障需求极为旺盛,然而,通过保险解决医疗费用支出的比例微乎其微。从中国现行社会保障体系的实际情况出发,结合国外长期护理领域的成熟产品以及中国老年人群的特点和护理需求,对如何做好老年人群的产品规划,促进保险产品创新,提出相应建议。     

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.

Trade liberalisation,market competition and wage inequality in China's manufacturing sector

Economic reforms of the late 1980s have contributed to rapid economic growth in China. While the overall standard of living has improved, economic growth has also resulted in an increase in income inequality. Rising income inequality can increase social tensions that can impede further economic growth. By making use of firm level panel data, this paper focuses on the impact of increased market competition and trade liberalisation on skilled–unskilled wage inequality in China's manufacturing sector. A theoretical model is used to argue that trade liberalisation and market competition can affect skilled–unskilled wage inequality. Based on this result, an econometric model is specified. The empirical analysis presented in this paper shows that increased trade liberalisation has contributed to an increase in skilled–unskilled wage inequality in China's manufacturing sector. However, increase in market competition has the opposite effect.     

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.
