我国高技术制造业竞争力及影响因素研究--基于BP-DEMATEL模型

Research on the Competitiveness of China's High-tech Manufacturing Industry and its Influencing Factors

国际间的竞争,归根到底是高端核心技术的竞争。高技术制造业是制造业中技术创新最活跃的部分,是驱动国民经济高质量发展的重要动力。基于近10年各省份的面板数据,从发展规模、产业扩张能力、创新投入及产出效益四方面构建高技术制造业竞争力的评价指标体系,运用因子分析方法,并结合BP神经网络建立的BP-DEMATEL模型,对我国四大区域及各省份高技术制造业竞争力水平进行综合分析与评价,探析高技术制造业竞争力的影响因素。研究发现,我国各地区高技术制造业发展不平衡,竞争力差异较大,东部地区竞争力较强;在影响高技术制造业竞争力的众多因素中,有效专利数是关键的原因型因素,出口是关键的结果型因素。

International competition,in the final analysis,is the competition of high-end core technology.High-tech manufacturing industry is the most active part of technological innovation in the manufacturing industry,and it is an important driving force to drive the high-quality development of the national economy.Based on the panel data of provinces,cities and autonomous regions in the last ten years,this paper constructs an evaluation index system for the competitiveness of high-tech manufacturing industry from four aspects:development scale,industrial expansion capacity,innovation input and output benefit.By using the method of factor analysis and the BP-DEMATEL model established by BP neural network,this paper comprehensively analyzes and evaluates the competitiveness level of high-tech manufacturing industry in four regions and provinces and urban areas in China.This paper makes an in-depth analysis of the factors affecting the competitiveness of high-tech manufacturing industry.It is found that the development of high-tech manufacturing industry in different regions of China is unbalanced,the competitiveness is quite different,and the competitiveness of the eastern region is strong;among the many factors affecting the competitiveness of high-tech manufacturing,the number of effective patents is the key cause-type factor.Export is the key outcome factor.
