【摘要】：在开放的经济系统中,决定一国技术进步的力量不仅仅是本国对研究开发的投入所带来的研发资本存量的累积,也来自于通过各种渠道溢出的国外研发投入所带来的研发资本存量的累积。溢出的国外研发资本对于经济水平和研究开发实力较弱的发展中国家显得更为重要：首先,发展中国家的研究开发受到本国经济发展水平的限制；其次,对外界已有知识和技术的重复研究与开发本身就是对资源的浪费。进口贸易为国外对本国的技术溢出提供了一个渠道。通过引进国外先进的最终产品和高品质的中间产品,可以直接或间接地提高一国的生产率水平。更重要的是,通过“干中学”效应、演示和培训效应等,一国可以了解与学习到进口产品中所蕴含的国外的先进技术,并经过吸收、模仿与二次创新,实现本国的技术进步和经济增长。理论界对进口贸易技术溢出效应的研究自20世纪90年代后逐步深入,研究基本上都是从国家层面上展开的。本文则从省际的角度出发,以安徽省为视角研究进口贸易的技术溢出效应促进安徽省经济增长的问题。本文从理论结合实际的角度阐述了进口贸易技术溢出效应促进经济增长的传导机制及其影响因素,并对安徽省进口贸易与技术进步的现状进行了深入的分析。在此基础上,本文利用扩展的CH模型,从不考虑人力资本因素和考虑到人力资本因素两个方面对安徽省进口贸易的技术溢出效应促进经济增长进行了检验,得到以下三方面结论：(1)安徽省进口贸易技术溢出效应存在：在不考虑人力资本因素的情况下,经进口贸易渠道溢出的国外研发资本存量每增长一个百分点,安徽省全要素生产率将增加0.244个百分点；在将人力资本因素纳入考察后,经进口贸易渠道溢出的国外研发资本存量每增长一个百分点,安徽省全要素生产率将增加0.026个百分点。(2)省内研发资本对安徽省全要素生产率的增长具有正向促进作用：在不考虑人力资本因素的情况下,省内研发资本存量每增长一个百分点,全要素生产率增加0.064个百分点；而加入人力资本因素后,省内研发资本存量每增长一个百分点,全要素生产率增加0.071个百分点。(3)安徽省人力资本不足限制了进口贸易技术溢出效应对全要素生产率的促进作用：在考虑到人力资本因素后,省内研发资本存量对安徽省全要素生产率的促进作用有所增强,而经进口贸易渠道溢出的国外研发资本存量对安徽省全要素生产率的促进作用显著减弱。基于前文分析的结果,本文提出了相关的对策建议：扩大安徽省进口贸易规模,优化进口贸易结构；提升省内人力资本水平,从而加强对进口贸易外溢技术的吸收能力；加大省内研发资本投入,加快自主创新的步伐。最后对全文进行了总结,并提出了一些不足之处,针对这些不足之处提出了后续研究的方向,即研究展望：(1)可将安徽省进口贸易的技术溢出效应与周边发达省份进行对比,使我们更加清晰地认识到安徽省进口贸易技术溢出效应的水平及与发达省份之间的差距；(2)实证考察安徽省某行业或产业进口贸易的技术溢出效应,使我们了解到不同行业或产业进口贸易技术溢出效应的强弱情况；(3)综合考察人力资本、进口渗透率、贸易开放度等多变量对安徽省进口贸易技术溢出效应的影响,以获得更加全面和客观的结果。
[Abstract]:In an open economy system , the power to determine the technological progress of a country is not only the accumulation of R & D capital stock brought by domestic investment in research development , but also the accumulation of R & D capital stock brought by the overseas R & D investment overflowing through various channels . The foreign R & D capital overflowing is more important to the developing countries with weaker economic level and research and development power : firstly , the research and development of developing countries are limited by their level of economic development ;
Secondly , the repeated research and development of external knowledge and technology is the waste of resources .

Import trade provides a channel for foreign technology spillover abroad . By introducing foreign advanced final products and high - quality intermediate products , the productivity level of a country can be improved directly or indirectly . More importantly , through the " dry middle school " effect , demonstration and training effect , a country can understand and learn the advanced technology of foreign countries contained in the import product , and through absorption , imitation and secondary innovation , realize national technological progress and economic growth .

This paper studies the spillover effect of import trade in Anhui Province from the perspective of inter - provincial perspective , and analyzes the current situation of import trade in Anhui province .
After the human capital factor is included in the investigation , the foreign R & D capital stock overflowing through the import trading channel increases by one percentage point , and the whole factor production rate of Anhui province will be increased by 0.026 percentage points . ( 2 ) The capital inventory in the province increases by one percentage point per growth without considering the human capital factor , and the total factor productivity is increased by 0.064 percentage points ;
After the human capital factor is added , the capital stock in the province is increased by one percentage point , the total factor productivity is increased by 0.071 percentage points . ( 3 ) The shortage of human capital in Anhui province limits the promotion of the whole factor productivity of Anhui province .
To improve the level of human capital in the province , thus enhancing the absorptive capacity of the imported trade spillover technology ;
The paper summarizes the full text and puts forward some shortcomings , and puts forward some shortcomings , and puts forward some shortcomings , which is the research prospect : ( 1 ) The technology spillover effect of import trade in Anhui province is compared with the peripheral developed provinces , which makes us more clearly aware of the level of the spillover effect of import trade in Anhui province and the gap between developed provinces ;
( 2 ) To investigate the technical spillover effect of import trade in some industries or industries in Anhui province , and make us know the intensity and weakness of the spillover effects of import trade in different industries or industries ;
( 3 ) To comprehensively study the effects of many variables such as human capital , import permeability and trade openness on the spillover effects of import trade in Anhui Province , so as to obtain more comprehensive and objective results .
