【摘要】：本文主要针对研发投资影响因素的稳健性进行实证研究,分别选取了中国省际数据2006-2010年的数据和金砖国家数据1999-2009年的数据作为研究样本。首先,分析国内外关于研发投资及其影响因素的研究现状,并系统地学习相关的理论和方法。其次,运用极值边界分析方法,以研发投资强度为被解释变量,以人力资本积累和科学研究人员数量为核心解释变量,以通过外商直接投资实现的国际技术转移、专利保护强度和经济增长为关注解释变量,同时引入人口密度、政府执行研发占总研发的份额,以及其他宏观经济变量,如固定资本形成增长率、固定资本形成占地区生产总值的比例、工业生产在地区生产总值中所占的份额、通货膨胀率、利率等为控制变量,建立极值边界分析模型,对研发投资影响因素的稳健性进行分析。在此基础上,针对三个关注的影响因素,提出三个假说,首先是国际技术转移假说,从国外研发活动的受益可以通过外商直接投资传输并影响国内研发投资的决策；二是专利权保护假说,研发投资率与知识产权和专利权的保护强度呈正相关；最后是收入增长假说,研发投资强度与收入变化密切相关。分析结果表明,一省或一国的高等教育和科研人员数量是对研发投资强度具有积极影响的稳健的决定因素,而通过外商直接投资实现的外国技术流入和收入增长率对一省或一国的研发投资无显著影响,专利保护强度对决定一省或一国研发投资具有稳健的积极影响。这一分析结果部分验证了假说一,即通过外商直接投资实现的国际技术转移对国内研发投资既有抑制作用,也有溢出效应。同时验证了假说二,即研发投资强度与专利保护强度呈显著正相关。最后否定了假说三的说法,实证结果说明研发投资强度与经济增长没有显著的正向或者负向关系。
[Abstract]:This paper mainly focuses on the robustness of R & D investment factors and selects the data of China inter-provincial data from 2006 to 2010 and BRICS data from 1999 to 2009 as the research samples. Firstly, the research status of R & D investment and its influencing factors at home and abroad is analyzed, and relevant theories and methods are systematically studied. Secondly, using the method of extreme value boundary analysis, taking the intensity of R & D investment as the explanatory variable, the accumulation of human capital and the number of scientific researchers as the core explanatory variables, the transfer of international technology through foreign direct investment (FDI). The intensity of patent protection and economic growth are explanatory variables of concern, along with the introduction of population density, the share of government R & D as a share of total R & D, and other macroeconomic variables, such as the growth rate of fixed capital formation, The ratio of fixed capital formation to regional gross domestic product (GDP), the share of industrial production in regional GDP, inflation rate, interest rate and so on are the controlling variables, and the extreme value boundary analysis model is established. The robustness of the factors affecting R & D investment is analyzed. On the basis of this, three hypotheses are put forward in view of the three influential factors. Firstly, the international technology transfer hypothesis. The benefits of foreign R & D can be transmitted through FDI and influence the decision of domestic R & D investment. The second is patent protection hypothesis, R & D investment rate is positively correlated with intellectual property rights and patent protection intensity, and finally is income growth hypothesis, R & D investment intensity is closely related to income change. The results show that the number of higher education and scientific research personnel in a province or a country is a robust determinant of the positive impact on R & D investment intensity. However, the inflow of foreign technology and the growth rate of income through FDI have no significant influence on the R & D investment of a province or a country, and the intensity of patent protection has a steady and positive impact on the R & D investment of a province or a country. The result of this analysis partly verifies the hypothesis that international technology transfer through foreign direct investment (FDI) not only inhibits domestic R & D investment but also has spillover effects. At the same time, it verifies hypothesis 2 that R & D investment intensity is significantly positively correlated with patent protection intensity. Finally, the hypothesis 3 is denied. The empirical results show that there is no significant positive or negative relationship between R & D investment intensity and economic growth.
