政府支持是新兴经济体企业“走出去”的重要推动力，但对于其是否有助于新兴经济体企业“走进去”这一问题，理论观点存在争议。为此，本研究探讨母国政府支持是否有助于以及何时有助于新兴经济体企业获得东道国合作伙伴的信任。本研究以中国为研究情境，通过匹配来自中国国有跨国企业海外子公司的高级经理的一手数据和公开的二手数据，进行实证检验。研究结果表明，母国政府支持有助于新兴经济体企业获得东道国合作伙伴的信任。当东道国的管制制度越优于母国的管制制度时，母国政府支持的促进作用增强；当两国的外交关系拉近、文化交流增强时，母国政府支持的促进作用减弱。本研究既拓展了新兴经济体企业国际化的研究，也揭示了外交关系和文化交流对微观跨组织关系治理的影响。

Government support has been recognized as a main impetus behind the internationalization of emerging multinational enterprises ( hereafter EMNEs) , but conceptual views are inconclusive regarding government support's impacts on EMNEs， post-entry operations. This research explores whether and when home country government support enables EMNEs to obtain foreign partners’ trust in the host markets. To test hypotheses, this research constructed a dataset that comprises of primary survey data collected from senior Chinese managers working for Chinese multinational companies' overseas subsidiaries and archival data. The findings indicate that home country government support is conducive for EMNEs to obtaining their foreign partners' trust. The positive impact becomes stronger when EMNEs operate in host countries that have more advanced regulatory institutions. However, in host countries that have tight diplomatic relationship and intensive cultural communication with the home countries, the impact of home country government support becomes weaker. This research extends the research on the internationalization of EMNEs and uncovers how diplomatic relationship and cultural communication at the macro-level affect interorganizational relationship management at the micro-level.
