基于我国沪深两市A股上市公司2008-2014年的财务数据，实证检验了企业研发投入对盈余管理的刺激作用及触发机制，并尝试从盈余管理的视角探讨微观企业对宏观产业政策的适应性行为。实证结果发现,企业研发投入刺激盈余管理行为的发生；盈余管理程度越大，企业获得的财税支持越多，且高研发组的敏感性更强；进一步研究发现，企业的这种盈余管理行为没有影响研发对企业价值的促进作用。

Using the data of A-share listed companies in SSE and SZSE from 2008 to 2014, this paper verified the stimulation and trigger mechanism from the earnings management by enterprise R&D, and tried to discuss the adaptive behavior of micro-enterprises to macroeconomic policies in the view of earnings management. We find that the enterprise R&D investment stimulates the enterprise earning management, and the bigger the enterprise earning management is made, the more financial and tax support the enterprises will obtain, and the enterprise with higher R&D investment will have higher degree of sensitivity. We also find that greater R&D intensity has a stronger positive effect on earnings management on governmental subsidy (tax preference). However, the earnings management does not affect the promoting role to the value of the enterprise.
