A Study On The Existence And Influencing Factors Of Reverse Technology Spillovers Effect

The existing research indicates that the main motive of China's OFDI is to acquire advanced technology abroad,which is due to the reverse technology spillovers effect(RTSE)may exist in the technology acquired OFDI.Based on this situation,in order to make enterprises go out better,improve the quality of OFDI and promote domestic technological progress,it is of great theoretical and practical significance to study the existence and influence factors of RTSE.Through literature research,this paper finds that most of the research is based on macro-based research,and the micro-angle research is relatively less;there are improvements of LP model which is the main framework of RTSE;Most of the existing researches are vague about the concept of RTSE.In this paper,the concept of RTSE is redefined,which is different from the net-RTSE under considering opportunity cost.By constructing a framework of mathematical analysis,it is found that when there is reverse technology spillover effect,even if there is no monopoly advantage,a positive profit can be obtained under certain conditions.There are two ways of the effect of technology gap on Reverse Technology Spillover effect,one is itself and the other is through influencing absorptive capacity.The technology gap and the reverse technology spillover effect show the "an inverted U".In the empirical analysis part of the micro level,the reverse technology spillover effect is preliminarily confirmed by the OLS and IV methods.Using the marginal treatment effect model,the total sample according to the level of technology is divided into five sections,respectively,estimated net reverse technology spillover effect of each interval value,results show that with the increase of the technical level,reduce the technology gap,net reverse technology spillover effect slowly increased at first,after the rapid decline in performance as "an inverted U which right side wider than left side".In the empirical part of the micro level,the exsist of RTSE is preliminarily confirmed by the OLS and IV methods.By using the marginal treatment effect(MTE)model,the existence of the net-RTSE is proved strictly.It is found that the relationship between technology level and net-RTSE is characterized by "reverse U" with "left width and right margin".The net-RTSE of single OFDI has been found that the first and second times are smaller,third times increased significantly,fourth times began to decline,and fifth times became negative.This may be associated with an increase in the number of OFDI accompanied by a narrowing of the technical gap.Among other factors,firm size,per capita salary,government subsidy,asset return rate and manufacturing industry's impact on reverse technology spillover effect are positive;income tax rate,financing cost,long-term asset liability ratio and ownership nature are negatively related.fn the macro-level empirical study,an improved LP model is used to find the existence of the reverse technology spillover effect on the macro perspective.Using panel quantile regression,it is found that the impact of the macro level technology gap on the reverse technology spillover effect is the superposition of multiple "inverted U".Finally,a summary of the full text analysis,give out the full text of the conclusion,and give the corresponding policy recommendations.The limitations and shortcomings of this paper are also analyzed,and the future research direction is also prospected.
