本文研究了内生技术变化和国际技术溢出对碳泄漏的影响。众所周知，一个地区单方面的二氧化碳减排政策可能会导致非减排地区的二氧化碳排放量增加，原因是二氧化碳密集型企业的搬迁和能源市场的影响。然而，如果二氧化碳减排政策在本国地区引发节能技术创新，并且这种创新可以自由地溢出到国外的能源用户，那么碳泄漏可能会被外国公司诱导的能效提高所抵消。在本文中，我们建立了一个简单的碳泄漏和技术溢出的数学模型，并用调整后的CGE模型进行了数值模拟，以说明国际技术溢出的潜在重要性。我们的研究表明，在适度的技术溢出水平下，碳泄漏可以变为负值。(C)2014爱思唯尔B.V.保留所有权利。
This paper studies the effect of endogenous technical change and international technology spillovers on carbon leakage. It is well known that a unilateral CO2 abatement policy in one region may cause CO2 emissions to increase in non-abating regions because of the relocation of CO2-intensive firms and because of energy market effects. If, however, the CO2 mitigation policy induces energy-saving technological innovation in the home region and this innovation can freely spill-over to energy users abroad, carbon leakage may be offset by induced efficiency gains in foreign firms. In this paper we develop a simple mathematical model of carbon leakage and technological spillovers and perform numerical simulations with an adjusted CGE model to illustrate the potential importance of international technology spillovers. We show that carbon leakage can become negative at moderate levels of technology spillover. (C) 2014 Elsevier B.V. All rights reserved.
