As the global climate warming, "haze" weather frequent, low-carbon economy research caused extensive concern of the academia, In this paper, we use panel data of 5 cites in China Guangxi province over the period 2000 to 2008, and construct a systematic model which concludes the factors of FDI technology of carbon emissions and carbon emission intensity. In addition, we refinement the relevant data of sub-regional study in order to receive an in-depth analysis of FDI impact on China’s carbon emissions under the influence of technology. As a result, there exists hysteresis in the impact of FDI on carbon emission in china, and lad FDI (lag 1 period) has significant positive effects on carbon emission. This article first analyses the background and connotation of low-carbon economy, low-carbon economy industrial park is analysed the related theoretical basis, and then analysed the necessity of the construction of low-carbon economy industrial park of Guangxi Beibu Gulf economic zone, finally we propose the construction of development model of low-carbon economy industrial park of economic zone of Guangxi Beibu Gulf.
