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.

“…In terms of the research area, Zhang Hong et al [ 16 ] evaluated the land ecological security in Dali City, and Liu Jiao et al [ 17 ] measured the comprehensive value of land ecological security in 129 counties (cities, districts) in Yunnan Province; Lu Guangbin et al [ 18 ] analyzed the overall change and spatial differentiation of land ecological security in Chongqing; Wang Yang et al [ 19 ] conducted a dynamic evaluation of the land ecological security in Zhengzhou from 2003 to 2017, and quantitatively analyzed and identified the main obstacle factors; Li Xuemei et al [ 20 ] investigated the spatial correlation and internal heterogeneity of land ecological security among various districts in Tianjin; Zhang Tao et al [ 21 ] predicted the comprehensive evaluation index and coupling coordination degree between urbanization development and land ecological security in Anhui Province; Hu Dongbin et al [ 22 ] analyzed the factors affecting land ecological security in Hunan Province; Zheng Lan et al [ 23 ] analyzed the dynamic change of land ecological security in Jiayuguan City and the primary influencing factors; Zhang Yanwen et al [ 24 ] explored the economic development and the level of coupling and coordination between its various subsystems and land ecological security in Guangdong. From the perspective of rural revitalization planning and development, Yang Jun et al [ 25 ] demonstrated that with the increase of construction land in China’s Liaodong Peninsula, the development of tourism can promote the economic development and growth of China’s non-urban communities; from the perspective of simulated urban landscape characteristics, Yang et al [ 26 ] systematically demonstrated that the mixed cellular automata model of urban landscape plays an active role in revealing urban land resource planning and land use change.…”

Land ecological security is the core of regional coordinated economic development and land ecological security planning. In this paper, with Shenzhen as the research area, 28 evaluation indicators were selected from 5 dimensions based on the DPSIR model to construct an indicator system for land ecological security evaluation, so as to evaluate the land ecological security status in the research area from 2009 to 2019. Based on the TOPSIS evaluation model, regional levels were determined, and finally the GM (1,1) model was adopted to scientifically predict the land ecological security system of Shenzhen from 2020 to 2025. The results showed that: (1) from the perspective of the main influencing factors, the weight of 16 indicators of Shenzhen’s land ecological security exceeds 0.03, including the total output value of agriculture, forestry, animal husbandry and fishery (D5) and Engel coefficient (I4). These factors are the main factors that have led to the deterioration of land ecological security in Shenzhen in the past decade; (2) comprehensive situation analysis revealed that from 2009 to 2019, the level of land ecological security in Shenzhen exhibited an increasing trend overall, but the land ecological security in Shenzhen still needs to be greatly improved; (3) regarding various subsystems, from 2009 to 2019, except the pressure subsystem which was in a downward trend, other subsystems showed a fluctuating and upward trend; (4) after modeling and calculation using the GM (1,1) model, it was concluded that most of the indicator factors are in a slow growing trend with the social and economic development of Shenzhen, but severe land ecological problem still exists. The research result is expected to provide a reference for the stable and sustainable development of society and economy and regional land ecosystem protection.
