Global Value Chain Embeddedness,Knowledge Spillovers,and Clustered Firms' Innovation Performance

Empirical evidence of the effects of global value chain( GVC) embeddedness on clustered firms' innovation is presented in this paper. The intermediary roles of the two types of knowledge spillover( explicit and implicit) in GVC embeddedness and clustered firms' innovation are considered, and the effects of structure embeddedness,relationship embeddedness,and acknowledgement embeddedness on clustered firms' innovation are examined. Analysis is based on the sample of 134 export-oriented firms from the Shaoxing industrial cluster in Zhejiang province of China. Results show that although GVC embeddedness is associated with high use of external knowledge sources,clustered firms' innovation is promoted indirectly through explicit knowledge spillover. Intrinsic connections exist among the different dimensions of GVC embeddedness,that is,structure embeddedness not only directly improves relationship embeddedness but also indirectly improves acknowledgement embeddedness through relationship embeddedness.

对相关市场条件下贸易竞争的博弈机制及福利效应的研究

在古诺双头模型的框架内分析了市场风险和相关因素对贸易竞争均衡和福利水平的影响.与传统模型不同,假设各国市场具有潜在相关的随机需求,且出口企业具有风险规避的态度,并利用博弈模型研究了市场风险和相关因子对竞争力和成本优势形成的产出效应及定价行为的影响.推论表明国际市场的不确定性和相关性削弱了企业在完全信息条件下参与贸易竞争的动机,而各国的福利水平则取决于企业风险态度、市场风险和相关系数的特定组合.
