Abstract

Based on the data of joint invention patents in Heilongjiang Province, the evolution process and spatial characteristics of collaborative innovation network in Heilongjiang Province are analyzed by using social network analysis and spatial analysis. The results show that the scale of collaborative innovation network in Heilongjiang Province continues to expand, the density continues to decline, and it has the characteristics of a small world. The core nodes of the network are mostly universities , followed by state-owned enterprises. "The number of private enterprises in the network is the largest, but their innovation ability is insufficient, and their innovation ability and innovation enthusiasm need to be further improved. The main forms of innovation cooperation are cooperation between enterprises , universities and scientific research institutions, and the number and strength of innovation connections in inter-provincial cooperation are higher than those in intra-provincial cooperation. The science and education re.sources in the province are not fully utilized, and industry-university-research cooperation needs to be strengthened At the same time , there are obvious spatial differences in the network. Domestic cooperation and intra-city cooperation are the main spatial scales, and the influence of geographical proximity gradually decreases. Harbin is the city with the highest innovation level in Heilongjiang Province, with close and extensive innovation links. Daqing, Mudanjiang and 0iqihar are in the second column of innovation capacity. Beijing, Jiangsu, Guangdong, Shanghai and Shandong are important external sources of knowledge in Heilongjiang province.
