随着新一轮科技产业革命的兴起,知识产权制度设计在推动技术创新方面的重要性日益凸显。本文采用自然语言文本处理分析方法,量化了69个经济体间签订的140份区域贸易协定文本中的知识产权保护深度,基于两个经济体之间共同发明的PCT国际专利数据,探讨知识产权保护的区域合作对跨境合作创新的影响及作用机制。研究发现,知识产权保护的区域合作与跨境合作专利间存在非线性的倒U型关系,但有78%的观测点并未超过曲线拐点,即对大多数经济体来说,加强知识产权保护的区域合作有助于其跨境合作创新产出提升。进一步研究发现,高制度质量能缓解知识产权保护区域合作对跨境合作创新的边际递减效应。同时,在低水平知识产权保护区域合作情况下,双边投资协定能够增强其对跨境合作创新的边际递增效应。由此提出我国进一步深度参与全球知识产权治理,优化国内制度环境,相机执择参与双边投资协定,以促进技术创新的对策建议。

无人机载雷达具有高机动灵活的特点,可解决传统非接触式生命体征感知中存在的探测范围小和探测场景受限等问题。该项研究工作将4D成像雷达搭载于多旋翼无人机上,提出一种基于点云配准的无人机载4D雷达生命体征感知方法。该方法通过对雷达点云进行配准和运动补偿,消除无人机在悬停状态时的运动误差干扰,进而对齐人体目标后实现生命体征信号的获取。仿真实验结果表明该方法能够对齐4D成像雷达点云序列,有效抑制无人机的运动干扰,从而准确提取人体目标的呼吸和心跳信号,为无人机载非接触式生命体征感知提供了一种新的技术途径。
