【摘要】 [目的/意义]近年来,中国内地学者的国际合著现象引起学术界的广泛关注。探讨参与国际合著的内地学者是否有助于提高科研产出,对于其建立国际合著关系以及提升科研影响力具有重要的参考意义。[方法/过程]以"技术创新管理"领域的139位内地学者为研究对象,采用倾向得分分层法考察了国际合著对内地学者科研产出的影响。[结果/结论]实证结果表明:"参与国际合著"的内地学者和"未参与国际合著"的内地学者在科研产出数量方面并未表现出明显差异;和"未参与国际合著"的内地学者相比,"参与国际合著"的内地学者具有更高的科研产出质量;由于国际合著隐含的沟通、协调和交通成本,"参与国际合著"高概率的内地学者反而降低了科研产出数量;"参与国际合著"中等概率和高概率的内地学者,比"参与国际合著"低概率的内地学者的科研产出质量更高。然而,"参与国际合著"中等概率的内地学者,比"参与国际合著"高概率的内地学者科研产出质量更高。更多还原

【Abstract】 [Purpose/Significance]In recent years,the phenomena of Chinese inland scholars with international co-authorships have received great attention in academia. By investigating whether international co-authorships contribute to improving research performance,the article provides important implications for inland scholars who wish to establish international co-authorships and improve research impact.[Method/Process]The article focuses on 139 inland scholars of China in the field of technology innovation management and investigates the impact of international co-authorships on research output with propensity score stratification method. [Result/conclusion]The empirical analyses indicate that,there are no obvious differences in research quantity between scholars who are involved in international co-authorships and those who are not; compared with scholars without international co-authorships,scholars who are involved in international co-authorships have higher research quality; however,because of the communication costs,coordination costs and traveling costs involved in international co-authorships,scholars with high probability of international co-authorships have lower research quantity; scholars with medium and high probability of international co-authorships have higher research quality than those with lowprobability of international co-authorships. However,scholars with medium probability of international co-authorships have higher research quality than those with high probability of international co-authorships.更多还原
