中文摘要：

在新常态下，中国经济由改革开放以来年均9．7％的高增长速度下滑到中高速增长，经济增长速度下调的压力大，稳增长是当前经济工作的重中之重。R＆D作为企业的一项投资活动，虽然是企业的自主行为，但也不可能不受到“操心”政府的影响。地方政府官员的异质性使得其对企业R＆D投资有抑制和促进两方面的作用，企业R＆D投资行为的经济后果对经济增长有直接的影响，即企业R＆D投资的增加意味着技术创新成果量的增加，而技术创新成果的增加意味着平均劳动生产率的提高，进而导致人均收入水平的提高，最终促进经济增长。

英文摘要：

Under the new normality, China＇s economy has slipped into medium-high growth rate from the high growth rate of annual average 9.7% since the reform and opening up; given the high pressure of the down-regulated economic growth rate, the steady growth has become the key of the current economic work. As an investment activity of enterprises, R＆D is the independent behavior of them; however, it is likely to be affected by the ＂worried＂ governments. The heterogeneity of local government officials is playing both a role of inhibition and a role of facilitation upon the R＆D investment of the enterprises. The economic consequences of enterprise R＆D investment behavior have a direct effect on economic growth, i.e., the increase of enterprise R＆D investment means the increase of the amount of technology innovation, and the increase of technical innovation means the improvement of average labor productivity, which may result in an increase in per capita income level, eventually the economic growth will be loromoted.
