| Summary/Abstract |
New energy development strategies play a crucial role in achieving urban green economic growth. Among these policies, new energy demonstration programs are a popular and effective strategy widely adopted among local governments in China. Despite the practical significance of these new energy demonstration programs, very few studies examined their implementation and actual effectiveness. This study aims to examine the development of China's new energy demonstration programs and further investigate their actual effectiveness from the perspective of urban green economic growth. Using a super-efficient Slacks-based measure model and the Propensity Score Matching plus Difference-in-Difference method, we found that, from the perspective of technological innovation, industrial structure and environmental constraint, the new energy demonstration programs have a positive effect on urban green economic growth, with a net policy effect of around 7.4%. Furthermore, due to the discrepancy in regional characteristics, the policy effect is relatively complicated with heterogeneity. We see a higher policy influence in eastern cities, sub-provincial capital cities and larger cities, as well as in cities with conducive institutional environment. This study has policy implications for the implementation of new energy demonstration programs in China.

| Summary/Abstract |
This paper aims to examine the role of the subway network, a typical form of transportation within urban areas, on innovation and knowledge diffusion. Applying the difference-in-differences strategy and spatial analysis, we used 1,332 newly opened stations in China from 2000 to 2013 as a quasi-experiment to identify the local effects of subway expansions. Results suggested that by reducing communication costs and increasing opportunities for interaction, subway construction would bring growth at the district level. Knowledge dissemination would become more active after new stations open. Micro-level results showed that these positive impacts were highly localized; that is, only those firms located within 1km around stations benefited from the new subway. Moreover, new subways facilitated the flow of knowledge from station to station and assisted firms in acquiring knowledge from more distant technology clusters conveniently.
