[Objective] This paper aimed to study the measurement and structure of carbon footprint and carbon capacity in Zhejiang Province, to evaluate its carbon security and to analyze its influencing factors so as to provide reference and basis for the development of low-carbon economy.[Methods] We calculated the carbon footprint, carbon capacity from 2000 to 2015 in Zhejiang Province, constructed an evaluation system with respect to carbon pressure index and carbon footprint index and used it to evaluate the carbon security in Zhejiang Province. The STIRPAT model and ridge regresion methods were used to analyze the influencing factors of carbon footprint in Zhejiang Province.[Results] The carbon footprint of Zhejiang Province experienced a process of increasing firstly and then decreasing slightly, and its carbon capacity was basically stable. The efficiency of energy utilization increased year by year, and the dependence of economic development on it reduced. The carbon pressure index ranged from 1.35 to 4.19; the carbon footprint index ranged from 0.21 to 0.59, which meant that Zhejiang's carbon footprint was above the average level in the world. Regression results showed that the drivers of carbon footprint in Zhejiang Province included population factors(population, urbanization rate), wealth factors(GDP), technical factors(secondary industry share, coal carbon footprint).[Conclusion] The level of carbon security in Zhejiang Province was relatively low. In order to achieve the goal of low-carbon economy, measures like controlling the population, improving the quality of urbanization, developing low-carbon industries, promoting the use of clean energy, protecting forests and increasing urban greening area, should be taken.
