知识溢出与区域经济增长的关系研究综述

在知识溢出与区域经济增长的关系上，存在MAR溢出、雅各布斯溢出、波特溢出三种不同的观点。MAR假说偏爱低竞争与产业专业化；波特也偏爱专业化，但赞成高竞争；而雅各布斯赞同高竞争与产业多样化。这三种假说都得到了实证经验的支持，结论差异的原因在于使用的方法、样本的时间和变量选取、研究的国家或地区的特征与产业不同。

Evaluation of investment subsidies: when is deadweight zero?

In the evaluation of investment subsidies one of the critical issues concerns the assessment of deadweight, that is, the degree to which projects would have been carried out without grant assistance. With the increasing restrictions on and cuts in subsidies for investment projects in the EU countries maximisation of the impact of the public resources that remain can be achieved through their allocation for projects with minimum deadweight. This paper studies the profile of subsidised zero deadweight investment projects – projects that would be abandoned without public subsidies – in Finland. The empirical analysis is conducted using micro level data on investment projects by private sector firms. The data set comprises 3,423 projects that were granted public investment subsidies between 2001 and 2003. Our results show that the likelihood of zero deadweight is significantly dependent on the characteristics of the subsidised firm, the characteristics of the investment project and the location of the subsidised firm.     

Unravelling the link between knowledge integration and new product timeliness

This paper examines the impact of knowledge integration on new product timeliness in Chinese high technology firms. The results show that the knowledge integration-new product timeliness connection is contingent on managerial factors (reward system and top management support) and product-based competencies (technical skills adequacy and marketing fit). The findings suggest that reward system, top management support and technical skills moderate the relationship between knowledge integration and new product timeliness. The implications for Chinese high technology firms and further research have been discussed.     

论高科技条件下的劳动价值创造与价值分配

高科技条件下创造价值的源泉仍然是劳动者的活劳动,其中,劳动者的知识创新活动是能够更有效地进行价值创造的活劳动,它在创造价值的活劳动中居于主体地位.因此,知识经济时代的价值分配应以劳动者的知识创新活动为中心,建立符合知识经济时代的价值分配导向体系.     

Consumers’ Appreciation of Regional Certification Labels: A Pan‐European Study

Successful regional products, such as Florida oranges, Idaho potatoes and Parma ham, often have to compete against products passing themselves off as the authentic product using the exact same name. This unfair competition misleads consumers, discourages small‐ and medium‐sized enterprises (SMEs) from marketing products based on their region of origin, and may end up hurting rural economies. To protect consumers, and support SMEs and rural economies, many countries around the world have introduced regulations enabling SMEs to legally protect the names of their regional products. The success of these regulations largely depends on consumers’ appreciation of regional certification labels that inform consumers that the name of the regional product is protected and that it denotes the authentic product. To gain an understanding about consumers’ appreciation of regional certification labels, this paper investigates consumers’ image of these labels and proposes a model that relates this image to consumers’ willingness to buy and pay for protected regional products. The model is tested based on Regulation No. 2081/92 that was introduced by the EEC allowing European SMEs to protect their regional products and market their products with a protected‐designation‐of‐origin (PDO) label. Structural equation modelling results suggest that consumers’ image of regional certification labels consists of a quality warranty dimension and an economic support dimension, which positively relate to consumers’ willingness to buy and pay for the protected regional product. Protecting regional products and marketing them with regional certification labels may be beneficial for SMEs producing and marketing regional products. Policy and managerial implications are discussed.
