技术转让在全球减少温室气体排放的努力中发挥着关键作用。在本文中，我们使用1995-2007年期间来自96个国家的详细专利数据来描述促进或阻碍气候友好技术国际传播的因素。这些数据提供了强有力的证据，证明宽松的知识产权制度对专利知识的国际传播产生了强烈的负面影响。对国际贸易和外国直接投资的限制也阻碍了无害气候技术的传播。令人惊讶的是，当地的技术能力往往阻碍转让。虽然技术能力的广泛指标预计将促进转让，后一种结果源于我们对当地能力的技术特定定义，这使得有可能捕捉到当地和外国发明之间的替代效应。
Technology transfer plays a key role in global efforts to reduce greenhouse gas emissions. In this paper, we characterize the factors that promote or hinder the international diffusion of climate-friendly technologies using detailed patent data from 96 countries for the period 1995-2007. The data provide strong evidence that lax Intellectual Property regimes have a strong and negative impact on the international diffusion of patented knowledge. Restrictions on international trade and foreign direct investment also hinder the diffusion of climate-friendly technologies. Surprisingly, local technological capabilities tend to discourage transfers. While broad indicators of technology capabilities are expected to facilitate transfers, this latter result stems from our technology-specific definition of local capabilities, which makes it possible to capture a substitution effect between local and foreign inventions.
