The Effect of Low-Carbon City Pilot Policy on Landscaping Construction Investment

Landscaping is an important component of low-carbon urban construction. In this paper, adopting the method of Differences-in-Differences, 141 prefecture-level cities in China are taken as samples to evaluate the influence of low-carbon city's pilot policies on the investment of landscaping construction, and to give a further analysis of the regional differences. The results show that, taking the demand of carbon sink and the low-carbon trend of landscaping construction as the orientation, the low-carbon city's implementation of pilot policy not only significantly increases the scale of investment in urban landscaping construction, but also has different influences on increasing investment in landscaping construction in various regions and cities. In terms of regional differences, under the influence of the policy, the investment in landscaping in the eastern and southern pilot cities increases remarkably compared with that in the non-pilot cities. From the perspective of city scale, the investment in landscaping construction has a significant increase in large and small cities, while it is not the case in medium-sized cities. Finally, some suggestions are put forward. According to the experience of low-carbon city pilot policies, local governments should be guided actively to make a series of policies on the perfect road-supporting green mechanism, and on the low-carbon investment system of landscaping in accordance with local conditions.
