【摘要】 在各要素全球流通的经济全球化时代，能够借助外国智力促进中国科研产出进而提升中国的科技创新能力至关重要。基于2002—2015年的省级面板数据，本研究实证检验了外国专家对各省份科研产出的影响效应。研究发现：(1)外国专家能显著提升各省份的科研产出水平，且在一定程度上克服潜在内生性问题后，其影响效应得到进一步增强；(2)外国专家对中西部地区省份和东部地区省份的科研产出的促进效应表现出明显的异质性特征；(3)基于门限模型，外国专家对各省份科研产出的影响具有非线性效应，表现为受到外国专家规模的约束。为此，中国应持续创新外国专家管理制度，优化外国专家引进项目结构，形成差异性的政策牵引，为持续稳步扩大外国专家来华规模创设充分的政策条件与制度环境。更多还原

【Abstract】 In the era of economic globalization where all elements circulate globally, it is crucial to use foreign intelligence to promote China’s scientific research output and thereby enhance China’s scientific and technological innovation capabilities.Based on provincial panel data from 2002 to 2015,this study empirically tests the impact of foreign experts on scientific research output in 30 China’s provinces.The study found that:(1)Foreign experts can significantly improve the scientific research output level of 30 China’s provinces, and after overcoming potential endogeneity problems to a certain extent, their impact is further enhanced;(2)Foreign experts’ positive impact on scientific research output shows obvious heterogeneity between central and western regions and eastern regions;(3)Based on the threshold model, the impact of foreign experts on scientific research output has a non-linear effect, which is constrained by the scale of foreign experts.To this end, China should continue to innovate the foreign expert management system, optimize the structure of foreign expert introduction projects, form differentiated policy traction and create sufficient policy conditions and institutional environment for the continued and steady expansion of the scale of foreign experts in China.更多还原
