In the era of the rapid development of knowledge economy and science, all countries have thought highly of technical innovation and greatly increased the R&D input for it. However, the research on the impact of R&D input on technical innovation lacks specialized, cross-country, and cross-time investigations, and especially, the research on small countries such as South Asia and Southeast Asia where technical innovation is relatively backward. So, does R&D input in South Asia and Southeast Asia have an impact on technical innovation and to what extent? Let us analyze the panel data of 18 countries in South Asia and Southeast Asia from 2001 to 2018, use three methods of unit root test to test the stationarity of variables, adopt the Kao cointegration test to test a stable long-term relationship between the variables, and then, respectively, carry out the transnational regression analysis of the difference between patent applications, scientific journal articles, and the R&D input with multiple models. Finally, the heteroscedasticity robust fixed-effect model is found to be the most suitable for this study after the comparative analysis of multiple models. Through the fixed-effect intercepts of each country in the heteroscedasticity robust fixed-effect models, South Asian and Southeast Asian countries are divided into three levels, and each level lists a set of equations. So, the following conclusions are drawn: both R&D expenditure and manpower input in South Asia and Southeast Asia significantly promote technological innovation; the efficiency of both R&D expenditure and manpower input promoting technological innovation in South Asia and Southeast Asia is low and needs to be improved. These conclusions provide references for policymakers in some countries where technological innovation is relatively backward, especially in Cambodia, Lao PDR, Myanmar, Timor-Leste, Bangladesh, Bhutan, Maldives, and Nepal.

研发投入对技术创新的影响：来自南亚和东南亚国家的证据

在知识经济和科学飞速发展的时代，各国都对技术创新寄予厚望，并大大增加了其研发投入。但是，关于R＆D投入对技术创新的影响的研究缺乏专门的，跨国的和跨时间的研究，尤其是对南亚和东南亚等技术创新相对落后的小国的研究。那么，南亚和东南亚的研发投入会对技术创新产生影响吗？让我们分析2001年至2018年南亚和东南亚18个国家的面板数据，使用单位根检验的三种方法检验变量的平稳性，采用Kao协整检验检验变量之间的稳定长期关系， 然后，分别使用多种模型对专利申请，科学期刊文章以及研发投入之间的差异进行跨国回归分析。最后，在对多个模型进行比较分析之后，发现异方差稳健的固定效应模型最适合本研究。通过异方差强健固定效应模型中每个国家的固定效应截距，将南亚和东南亚国家分为三个级别，每个级别列出了一组方程。因此，可以得出以下结论：南亚和东南亚的研发支出和人力投入均显着促进了技术创新。研发效率 促进南亚和东南亚的技术创新的D支出和人力投入很低，需要改进。这些结论为一些技术创新相对落后的国家的决策者提供了参考，尤其是在柬埔寨，老挝，缅甸，东帝汶，孟加拉国，不丹，马尔代夫和尼泊尔。
