By conducting field investigation on 200 enterprises in Shenzhen, this paper finds that currently, the low-carbon technology innovation of enterprises proceeds slowly and most enterprises adopt the incremental innovation approach in innovating low-carbon technology. One of the main reasons for the slow process of enterprise low-carbon technology innovation is that enterprises invest too much in existing equipment and lack confidence in low-carbon technology which is characterized with market uncertainty and has great market risk. To accelerate the process of enterprise low-carbon technology innovation, it is crucial for the government to provide policy support and powerful guidance. The government can encourage enterprises to introduce the low-carbon project through tax incentives, increase the fund support to enterprises under transition to low carbon and assist enterprises to introduce high-quality talents in low carbon to promote the low-carbon technology innovation of enterprises.
