Abstract: By making use of the panel data of 31 provinces in China from 2004 to 2013, this paper investigates the impact of ecological capital on the accumulation and innovation of human capital from the perspective of the externality of ecological capital. The results of this empirical study show that the ecological capital can improve the accumulation of human capital. Ecological capital cannot directly lead to the improvement of the innovation efficiency, its innovative effect is mainly reflected on its externality; human capital accumulation is the major channel of the innovative effect of ecological capital. The mechanisms of the innovative effect of ecological capital mainly include three aspects: firstly, ecological capital can improve the health human capital, so as to improve the innovation level; secondly, ecological capital can help to aggregate human capital and improve the social capital with the characteristics of social network and intercommunication, so as to promote the innovative inspiration of the whole society; thirdly, ecological capital can also improve people’s awareness of happiness, so as to improve the innovation and the innovative ability of individuals in their work. It is necessary to invest more in ecological capital and human capital so as to promote the green development and the innovative development.
