Is the digital economy a “bonus” or a “ minus” for cities to save energy and reduce emissions? This paper empirically tests the impact mechanism of the digital economy on urban energy saving and emission reduction from the perspective of technological progress and structural transformation using a panel data of 243 cities in China from 2011-2019. It is found that the digital economy is a “double-edged sword” for energy saving and emission reduction significantly increasing the scale of urban power consumption and CO 2 emissions but reduces the intensity of power consumption and CO 2 emissions. The mechanism test results show that the energy rebound effect of green technology innovation exceeds the energy-saving effect of green technology efficiency improvement. Therefore, the digital economy increases urban power consumption and CO 2 emissions by promoting green technology progress. The digital economy increases urban power consumption by promoting the transformation of industrial structure, but significantly reduces the intensity of CO 2 emissions. In detail, the structural transformation of the manufacturing industry has the effect of emission reduction, while energy saving and emission reduction effects of both agriculture and service industry are not significant due to the low-end industrial structure. In addition, a good environment of government green digital governance can strengthen the energy saving and emission reduction effects of the digital economy. The research conclusions can provide enlightenment for the digital transformation of urban economy and the formulation of energy saving and emission reduction strategies under the “dual carbon” goal.
Cities play a key role in the national scientific development and technological innovation, and we must firmly promote scientific and technological innovation around the development direction determined by the country. In order to build Chinese path to modernization and promote urbanization, innovation in basic theory, basic technology（including underlying technology） and applied technology must be put in the first place to promote the rejuvenation of the Chinese nation. It has been the unremitting pursuit of the Chinese people since modern times to help the national rejuvenation with science and technology. Building a modern country is the great awakening of the Chinese nation. We must absorb all the outstanding achievements of human civilization to promote Chinese path to modernization. In the process of urbanization, we should promote organized market-oriented applied basic research to meet the coming intelligent society, create a good ecosystem for organized market-oriented applied basic technology, and pay attention to and grasp the internal logic of the upcoming fourth industrial revolution.
Based on the questionnaire data of Qingcheng Station in Hohhot, this paper uses single-factor analysis of variance, structural equation modeling and modified IPA methods to explore and analyze the public satisfaction with urban toilets, empirically testing the effect of urban toilet revolution. The results show that the average of the public overall satisfaction with Qingcheng Station under the Likert Scale is 3.77, which is above the average level. Differences in individual characteristics significantly affect satisfaction with urban toilet renovation. Functional facilities, planning and layout, management work, and detailed design have a positive impact on overall satisfaction. The impact of architectural landscape on overall satisfaction is not significant. In the future, it is necessary to improve some aspects including humanized design and service, facility management and maintenance, civilized publicity.
High-quality development in the Yellow River Basin is predicated primarily on the development of urban agglomerations. This paper follows the fundamental characteristics of the spatial attributes of urban agglomerations, constructs the index system of urban agglomerations’ high-quality development based on the logic of element-structure-conditions-function, takes eight urban agglomerations, including the urban agglomerations of the Yellow River Basin and other urban agglomerations as case studies and measures the level of urban agglomerations’ high-quality development based on the regional comparison. The absence of high-level urban agglomerations highlights the variable development of urban agglomerations in the Yellow River Basin, according to the study. By measuring and identifying the industrial division of labor and spatial stratification of each city cluster and empirically examining their effects on high-quality urban development, we find that the dual constraints of the industrial division of labor and spatial stratification are the primary reasons for the lack of high-quality urban clusters in the Yellow River basin. Based on the theoretical analysis, we propose a viable strategy for the high-quality development of the Yellow River Basin to construct a high-level urban agglomeration by overcoming the dual constraints of industry and space.
By using questionnaire data and POI data, this paper analyzes the difference between residents’ demand and supply of public service functional facilities in Shanghai, and calculates the matching efficiency of supply and demand of functional facilities in each street and district of Shanghai. The results found that there are significant differences in the demand preferences of residents with different characteristics for public service functional facilities. The supply mismatch of public service functional facilities in Shanghai is widespread, showing the phenomenon of excess and insufficient supply of service resources. According to the mismatch of resources, streets and districts in Shanghai can be divided into 15 types of public service facilities. The paper puts forward strategies for governance from three aspects which are supply layout, supply information and supply subject. And provides reference frame for the renewal of community life circle and the improvement of the supply efficiency of functional facilities space.
