研究了杂交水稻育种技术创新网络的演化规律,完成了对无标度网络度分布的精确数学推导。结果显示:杂交水稻育种技术创新网络以S-曲线增长,遵循正态年龄分布修正的优先链接机制,是符合幂率分布的无标度网络。该研究结果补充和丰富了Barabasi无标度网络的增长机制和优先链接机制。相关创新组织和管理部门可以根据上述规律制定针对性的创新发展战略和创新指导政策,使创新组织获得领先技术创新优势,引领中国的创新行业抢占全球技术创新的制高点。
The evolution of the innovation network of hybrid rice breeding technology was studied, and the exact mathematical derivation of scale-free network distribution was completed. The results showed that the innovation network of hybrid rice breeding technology increased with S-curve and followed the preferential link mechanism modified by normal-age distribution. It was a scale-free network which accords with the power distribution. The results complement and enrich the Barabasi scale-free network growth mechanism and priority link mechanism. Relevant innovation organizations and management departments can formulate targeted innovation and development strategies and innovative guidance policies based on the above rules so that innovation organizations can gain the advantage of leading technological innovation and lead China’s innovation industries to seize the commanding height of global technological innovation.
