摘　　要：利用2012年世界银行关于中国制造业企业的调查数据,从外部和内部两个维度探讨了信息共享对企业生产率的影响。结果显示,在控制其他条件不变时,外部信息共享和内部信息共享都对企业生产率具有显著且稳健的正向促进作用,其中,外部信息共享对企业生产率的促进作用强于内部信息共享。对于计量模型中可能存在的内生性问题,采用处理效应模型和上市公司面板匹配数据进行缓解和验证,较大程度地提高了研究结论的可靠性。异质性分析结果显示,区域归属、行业性质、企业规模及企业年龄不同,信息共享对企业生产率的影响也有所不同。作用机制分析发现,内外部信息共享主要通过促进企业产品创新和管理创新来提高企业生产率。考虑相应的环境因素后发现,信息化水平、法律环境和市场化程度在外部信息共享和内部信息共享的生产率效应中呈现出相反的调节作用。This paper discusses the impact of information sharing on enterprise productivity from both external and internal dimensions using 2012 World Bank survey data of Chinese manufacturing companies. The results show that both external information sharing and internal information sharing have a significant and steady positive promoting effect on enterprise productivity when other conditions are controlled to be unchanged. External information sharing has a stronger promoting effect on enterprise productivity than internal information sharing. For the endogeneity problems that possibly exist in the measurement model,this paper uses processing effect model and panel matching data of listed companies for alleviation and verification,which improves the reliability of the research conclusions to a greater degree. Heterogeneity analysis results show that the impact of information sharing on enterprise productivity are different with regional ownership,industry nature,firm size,and enterprise age. Analysis of the mechanism of effect shows that internal and external information sharing can enhance enterprise productivity mainly by promoting product innovation and management innovation. The paper finds after considering the corresponding environmental factors that the informatization level,legal environment and degree of marketization play an opposite regulating role in the productivity effect of external information sharing and internal information sharing.
