技术对外依赖的测度、效应及影响因素研究

近年来，随着关键核心技术“卡脖子”对我国经济和产业稳定发展产生的影响越来越明显，技术对外依赖成为亟待研究的重要问题。基于对现实问题的分析，结合现有关于技术对外依存度研究中指标定位、测算范围和层次等方面存在的局限，项目从精准测算对外技术依存度指标入手，提出基于微观技术和基于多指标数据的两种计算方法，明确7种技术对外依赖的类型。以此为基础，构建空间计量模型，探索不同类型技术对外依赖对技术进步和经济增长带来的不同影响，识别对因变量存在显著影响关系的自变量及其定量关系。针对能够显著影响技术进步和经济增长的技术对外依赖类型，继续构建模型探索影响技术对外依赖的因素及定量关系，从而为提出解决技术对外依赖问题的政策建议提供理论和实证依据。

In recent years, with its increasing impact of science and technology “bottlenecks” on the stable development of China's economy and industry development, technological dependence on foreign countries has become an important issue to be addressed. Bearing in mind of the limitations of the existing research on technological dependence index in terms of its position, measurement scope and level, based on the analysis of the practical problems, this project starts with the accurate measurement of technological dependence index, proposing two calculation methods based on micro technology and multi index data, and categorizing seven types of technological dependence. To identify the problem of external dependence, we first build a spatial econometric model to explore how the different types of technological dependence are affecting on technological progress and economic growth. In order to do so, it investigates the independent variables and their quantitative relationships that have significant impact on the dependent variables. In order to provide theoretical and empirical foundation for policy recommendations, this project further develops a model to explore the factors and quantitative relationships of technological dependence and its impact on technological progress and economic growth.
