摘要
本文先通过一个两人合作模型,刻画了研究质量与合作者技能差异之间的倒"U"形关系。然后,本文基于中国知网2001—2017年12家中文经济学期刊论文数据对此命题进行了经验检验。结果表明,对应于研究质量和技能差异不同的测度方式,上述倒"U"形关系均显著;而且,由于技能差异指标的实际统计均值都小于由倒"U"形关系确定的"最优值",说明中国经济学领域跨界合作仍有待提高。
We first develop a model to analyze the inverted-U-shape relationship between coauthor skill differentiation and research quality. We then test this result empirically using the data of all articles published on twelve selected Chinese economics journals from 2001 to 2017. We show that the "inverted-U-shape " relationship does exist significantly and is very robust to different measures of skill differentiation and research quality, and "cross-field" cooperation is still insufficient at least for Chinese economic research insofar as the observed average skill differentiation is smaller than the optimal differentiation derived from the inverted-U-shape relationship.
