Industrial structure upgrading is a huge driving force for China’s green economic development. The Yangtze River Economic Belt (YREB), a crucial component of China’s spatial economic pattern, is facing the dual pressure of economic development and environmental protection. Therefore, it needs to have its industrial structure upgraded immediately. This article measures the development levels of green finance using the entropy method and bases its analysis on the panel data of 11 provinces (municipalities) in the YREB from 2005 to 2019. A moderated mediating effect model is then built to thoroughly examine the influence paths of green finance and green technology innovation on industrial structure upgrading. According to the empirical findings, green finance and green technology innovation have a significant direct role in promoting the upgrading of industrial structures. They reflect significant regional disparities across the East, Midland, and West. Second, green technology innovation has an effective transmission mechanism in green finance, boosting industrial structure upgrading. Third, environmental regulations positively regulate green finance’s direct and indirect routes to support industrial structure upgrading. This study is the first to combine green finance, green technology innovation, environmental regulation, and industrial structure upgrading under one research framework, broadening the research scope of industrial transformation. These research findings provide theoretical and practical guidance for upgrading China’s Yangtze River Economic Belt’s industrial structure.

With the continuous practice of the “Belt and Road” initiative, the countries along the “Belt and Road” have achieved rapid social and economic development. However, environmental problems have become increasingly prominent. Around the world, there are comments that China’s “Belt and Road” initiative is a result of resource plundering, transfer of backward production capacity, and environmental degradation of countries along the line. This study quantitatively evaluated the static, dynamic, linear, and non-linear effects of China’s foreign direct investment on the carbon emissions of countries along the line. The results showed that: (1) The direct effect of China’s foreign direct investment on the carbon emissions of countries along the route was significantly negative. (2) The economic scale and industrial structure effects of China’s foreign direct investment increased the carbon emissions of countries along the route. The production technology effect suppressed the carbon emissions of countries along the route and played a leading role. (3) The estimation results of the system generalized method of moments showed that the carbon emissions of countries along the route were significantly affected by the lag period, but the impact was small. (4) The results of the threshold regressive model showed that the GDP and proportion of industrial added value had significant threshold effects on the carbon emissions effect of China’s outward foreign direct investment. When the GDP of countries along the route exceeded 7.2696, China’s outward foreign direct investment carbon emissions reduction effect could not be realized; when the proportion of the industrial added value of countries along the route was lower than 4.0106, China’s outward foreign direct investment carbon emission reduction effect could not be realized. Based on the research conclusion, we concluded that China and countries along the “Belt and Road” should strengthen cooperation on carbon emissions reduction, jointly promote low-carbon construction of industrial parks, accelerate cooperation on green energy projects, and establish a green development fund to achieve sustainable development of the countries along the “Belt and Road”.

The Chinese government has continuously stressed the Chinese model and its characteristics for national economic governance. As a result, it is worth studying the effect of China’s rule of law on the government’s sustainable economic management, and the rule of law regarding this model can also provide a reference for governing other countries. This paper adopts the multiple linear regression analysis method using time-series data from 2007 to 2017 and from 2002 to 2019. This reflects the rule of law in the government’s sustainable economic management via the impact on government institutions, people’s courts, people’s procuratorates, and social organizations on the economy. The results show that the economic effect of the rule of law on government sustainable economic management is not significant. The rule of law in fiscal revenue and social organizations, rather than being arbitrarily dictated by powerful people, positively affects the economy. This effect was seen only in the 2002–2019 time series, but not in the 2007–2017 time series. Based on these results, it is suggested that China should strengthen the rule of law in managing its courts and procuratorates to enhance their roles in ensuring and accelerating sustainable economic development and regulating government activities. That is, the economic management effect of the public sectors, which indirectly participate in economic governance, is insufficient. This and other insightful policy recommendations are suggested to assist the government and policymakers in more effective and efficient sustainable economic management. Therefore, the system and regulations regarding their governance should not only focus on economic effects but also pay attention to the sustainable effects of economic development.
