The Impact of Technology Innovation on Urban Land Intensive Use in China: Evidence from 284 Cities in China

Abstract

How to improve the level of urban land intensive use (ULIU) has been of wide concern to academic circles. Technology innovation, as the internal driving force of economic development, has an important impact on ULIU. To clarify the impacts of technology innovation on ULIU, this study measures the ULIU level index of China from 2006 to 2019 from four dimensions: the input-output level of economic efficiency, the carrying capacity of ecological environment, the harmony of the man-land relationship and the rationality of relationships between regions. On this basis, as there are different production technologies and land use technologies between cities, the differences of ULIU in different regions are analysed. Using the spatial econometric model, this study empirically analyzes the impact of technology innovation on ULIU. In addition, considering the differences in geographical distribution, natural resource endowment and technological type, this study analyzes the heterogeneous impact of technology innovation on ULIU. The main conclusions are as follows: (1) The level of ULIU and technology innovation in China is increasing year by year. The level of ULIU and technology innovation in the eastern region is higher than that in the central and western regions. (2) From the spatial perspective, ULIU has a significant positive spatial spillover effect. (3) On the whole, technology innovation significantly improves the level of ULIU. (4) The impact of technology innovation in different regions, different types of cities and different types of technologies on ULIU is heterogeneous. Our results not only enrich the research on the relationship between technology innovation and ULIU, but also provide a reference for the formulation of relevant policies.

Phased Research on Effective School-Enterprise Cooperation

“…From the students' point of view, according to the talent cultivation programme formulated by the school and enterprise together, the students are equipped with the professional ethics, technical skills and comprehensive quality required by the enterprise and the society, and have comprehensive growth and development; from the teachers' point of view, the teachers of the school go to the enterprise for attachment and exercise, and the enterprise arranges part-time teachers to teach in the school, so that the full-time teachers and the part-time teachers have grown and progressed, and their teaching ability and practical ability have been improved (Guo & Du, 2022). Specifically, this is mainly manifested in the two aspects of each subject giving full play to their respective functions and effectively utilising other external resources (Zhang & Wang, 2021).…”

The impact of industrial collaborative agglomeration on total factor carbon emission efficiency in China

“…Since panel data are spatially correlated, ignoring spatial correlation may make the estimation results inaccurate 83 . Therefore, the spatial econometric model is further used.…”

Mega-cities dominate China’s urban greening

“…While the high levels of tree cover increase in China's mega-cities seems to be a success-story at the first glance, the high maintenance costs 13 associated with irrigation 44 needs to be factored in when evaluating the sustainability of such projects. To reduce costs and ensure a sustainable development, a natural-based planning in early urbanization stages is required 45 , including the use of local tree species that are adopted to the local climate and the preservation of existing trees.…”
