China has embarked on a new journey of building a modern socialist country in all respects. It is of great theoretical and practical significance to discuss how to achieve the goals of reaching peak carbon emissions and basically realizing modernization together. Based on the statistical data of provincial carbon emissions and economic development characteristics from 1997 to 2019, this paper proposed an empirical model of systematic analysis using the improved Kaya‑GDIM model and the expanded economic growth model, with total energy consumption as the transmission variable. This paper also used the Mann Kendall trend test, the Tapiocarbon decoupling index, and other methods to study and judge provincial carbon emissions and economic development status. On this basis, we divided the provinces with similar characteristics into groups. Based on the comprehensive investigation of the characteristics of the driving factors of combined carbon emissions and economic growth among provinces, we proposed a matching coordinated realization scheme for the goals. The results showed that: ① According to the comprehensive judgment based on the multivariate index, 30 provinces could be divided into four categories. ② Provinces should choose the coordinated realization scheme according to the characteristics of their carbon emissions and economic development driving mechanisms. The leading demonstration group should focus on the deployment and R&D of high energy efficiency technology and the improvement of total factor productivity. The quality improvement group should focus on promoting the transformation of production factors from quantity to quality improvement. The quantity growth group should focus on improving the dilemma of insufficient quantities of physical and human capital. The structural transformation group should adhere to the energy transformation and ensure a fair transformation. ③ In recent years, the slowdown of economic growth has effectively alleviated the rapid increase of carbon emissions. However, there is still much room for improvement in relevant work. In the future, we must speed up the low carbon regulation capacity and promote the decoupling of economic growth from carbon emissions, which are key to the smooth realization of the goals of reaching peak carbon emissions and basically realizing modernization.

Taking 111 prefecture- level resource- based cities in China from 2003 to 2015 as objects, this paper employed the dynamic principal components analysis to discuss the measurement of smart development and environmental quality and used coupling coordination model and panel VAR model to measure the coupling relationship and its interactive response mechanism between smart development and environmental quality in different types of Chinese resource- based cities. The results show that: (1) The smart development in Chinese resource-based cities has relatively low level, and the differences in its regional areas have been weakened. The environmental quality needs to be improved and its regional differences has widened in fluctuations. (2) The coupling and coordination relationship between smart development and environmental quality needs to be improved. The order of coordination from high to low is growth type, recession type, regeneration type and maturity type. (3) There are self- enhancement effects and inertial development trends in response mechanism between smart development and environmental quality in different types of Chinese resource- based cities. Besides, the smart development in Chinese resource- based cities has a significant negative effect on the environmental quality after a positive effect. And that, the smart development has a significant positive enhancement effect on the environmental quality in mature type of resource-based cities. However, the environmental quality in recession type of resource-based cities has a significant positive effect on the smart development after a negative effect and the smart development in regeneration type of resource-based cities has a significant positive effect on the environmental quality after a negative effect. In the next 15 years, the smart development in regeneration and maturity types of resource- based cities will improve environmental quality. Finally, this paper proposes different strategies and suggestions for transformation progress in different types of Chinese resource-based cities. [ABSTRACT FROM AUTHOR]

The study of the coupling relationship and coupling path of carbon emission efficiency and industrial structure upgrade is of great practical significance to the green development of China in the new era and for the construction of a beautiful China. Firstly, the carbon emission efficiency is calculated by the super- efficient SBM model containing undesired output. Then, the coupling degree between the efficiency of regional carbon emission and the industrial structure upgrade is calculated and analyzed by the extended coupling model, and the provinces are divided into multiple layers according to their coupling degrees and coupling characteristics. Finally, the coupling path of the two factors is designed under the framework of dynamic distribution. The research found that: (1) There lies an obvious difference between the spatial and temporal pattern of carbon emission efficiency and high-grade industrial structure level. In terms of their coupling degrees, nearly half of the provinces are between 0.2 and 0.4, which can be considered as moderately and mildly imbalanced recession. Besides, according to the coupling characteristics, nearly half of the provinces belong to the coupling type of "low level coordination" with low development degree and high coordination degree. (2) There is an obvious inconsistency between carbon emission efficiency and the industrial structure upgrade in China from the aspect of reginal dynamic distribution. The former has a severer degree of cure than the latter. Therefore, China should improve the degree of coupling between regional carbon emission efficiency and industrial structure on the basis of mitigating the solidification of interregional carbon emission efficiency. (3) The paper designs the coupling path of carbon emission efficiency and the industrial structure upgrade in China on the basis of the coupling classification diagram, which can not only alleviate the dynamic incoordination of the two factors, but also effectively enhance their coupling degree among regions of China.
