Abstract :
In the context of high-quality development and regional integration, understanding the impact of spatial correlation network structure (SCNS) of urban agglomerations on high-quality economic development (HQED) is crucial for achieving regional high-quality integrated development. However, previous studies have primarily focused on "attribute data," neglecting the advantages of "relationship data" in identifying spatial correlations and the value of network structure in influencing the performance of "attribute data." To address this gap, this study utilizes panel data from 41 cities in the Yangtze River Delta urban agglomeration (YRDUA) from 2010 to 2021 to examine the overall network structure (ONS) and individual network structure (INS) characteristics of HQED. Building on this foundation, it further explores the impact of SCNS on HQED and its heterogeneity. To achieve this objective, we employ social network analysis (SNA), panel data regression models, and spatial panel quantile regression (SQR) models to analyze these relationships. The results show that: (1) The overall network structure for HQED of the YRDUA remains relatively stable, the extent of correlation closeness requires enhancement. (2) The cities of Wuxi, Suzhou-S, Shanghai, Changzhou, and Nanjing occupy central network positions, functioning as "intermediaries" and "bridges." (3) An increase in network density and a decrease in network efficiency significantly improve the overall HQED level of the YRDUA and reduce internal differences within the urban agglomeration. Furthermore, degree centrality, closeness centrality, betweenness centrality, in-degree, and out-degree all significantly promote urban HQED, with evident urban heterogeneity in the effects of individual network centrality. This finding enriches the theoretical framework for spatial analysis for the HQED of urban agglomerations and provides valuable policy recommendations to promote the high-quality integrated development of urban agglomerations.

Abstract :
新质生产力是契合新发展要求的先进生产力,也是推进经济高质量发展的关键驱动.本文从物质生产力、精神生产力、生态生产力和社会生产力构建新质生产力评价指标体系,利用CRITIC法对2011~2022 年中国284 个城市的新质生产力水平进行测度,采用Kernel密度估计、Dagum基尼系数、方差分解和障碍因子诊断等方法探究其动态演进、区域差异和障碍因子.研究发现:新质生产力总体水平呈持续增长态势,四大区域呈"东部-中部-东北-西部"递减状态;新质生产力水平的总体差异呈现波动下降的趋势,区域间差异是最主要空间来源,物质生产力差异是最主要结构来源;科技存量、能源结构和工业数字化是制约中国新质生产力发展的主要障碍因子.

Abstract :
Under the requirement of the high-quality development of the Chinese economy, how promoting the transformation of industrial structure toward a cleaner path has become an urgent task. Most studies have examined the role of technological advancement in industrial transformation, but few have considered the impact of carbon-saving technological advancement. To address this gap, this paper utilizes provincial-level data from China covering the period 2004 to 2021 and employs a stochastic frontier model to calculate a carbon-saving technological progress index. Based on this, the spatial Dubin model was employed to investigate its effects on the cleanliness of industrial structures. The findings reveal that: (1) Carbon-saving technological advancements significantly promote the cleanliness of industrial structure in China through pathways of energy efficiency and consumption upgrading, with positive spatial spillover effects. (2) As the level of the cleanliness in industrial structure improves, the impact of carbon-saving technological advancements follows a "U"-shaped trajectory, initially declining before rising. Additionally, the influence of heterogeneous environmental regulation levels is determined to be complex. (3) The impact of carbon-saving technological advancement is most pronounced in the northeast region, followed by the central and eastern regions, with the western region exhibiting the weakest effect. These findings provide crucial policy implications for advancing technological innovation and sustainable development under China's "new normal" economic context.

Abstract :
低碳城市试点政策具有先行先试和由点及面的特点,对于我国实现碳达峰碳中和目标和推动绿色发展具有重要意义.本文基于空间二元选择模型探究影响低碳城市试点选址的空间因素,利用两机制空间杜宾模型区分试点城市和非试点城市之间绿色增长的双向非对称空间依赖关系.研究发现,研发创新能力强、经济发展水平高和第二产业增加值占比较低的城市更有可能入选低碳城市试点,且省(区、市)内城市入选试点有助于提高邻近城市下一轮入选低碳城市试点的概率.进一步研究发现,试点政策的绿色增长空间溢出效应显著,我国试点城市与非试点城市之间属于互惠互利的良性竞争.此外,城市第二产业增加值占比较高对城市绿色增长产生影响,因此试点城市存在如何解决第二产业碳排放高的现实问题.空间溢出机制分析结果表明,试点城市和非试点城市之间污染密集型产业和绿色创新资源的空间转移机制具有非对称性.本文研究为我国进一步完善低碳城市试点政策和促进绿色经济增长提供了实证依据和有益参考.

Abstract :
Digitalization provides a new impetus for technological innovation in manufacturing enterprises. However, research on the influence of digitalization on technological innovation is still in an exploratory phase, lacking a systematic theoretical framework and unified conclusions. It is crucial to clarify the mechanisms by which enterprise digitalization impacts technological innovation and to confirm the role of digitalization in promoting technological innovation in the digital era. The listed A-share manufacturing enterprises in China from 2010 to 2019 serve as the research samples in this study. Moreover, the influence mechanism and effect of enterprise digitalization on technology innovation are studied at the micro level. The improvement of enterprise's digital level can facilitate technology innovation, and this effect continues to be significant after a series of endogenous and robustness tests are performed, as indicated by the results of this study. In the above research, a more comprehensive and in-depth discussion at the micro level has been conducted to gain more insights into the correlation between enterprise digitalization and technology innovation, such that the black box of digitalization affecting technology innovation can be revealed more effectively.
