Regional green technological progress is an important driver of regional green technology innovations. To explore in depth the impact of green finance and international technology spillover on regional green technology innovation, this study incorporates green finance, international technology spillover, and green technology innovation into the same analytical framework. In addition, based on a new perspective of regional innovation capabilities, this study analyzes the impact of green finance and international green technology spillovers on green technology innovation. The data were collected in 30 Chinese provinces from 2003 to 2019 and analyzed by a panel fixed-effects model. The interaction between green finance, international technology spillover, and regional innovation capability was investigated to understand the impact of each interaction on green technology innovation. Second, regional innovation capability was used as an intermediary variable to identify its underlying mechanism. Finally, the spatial spillover effect of green technology innovation was analyzed using the spatial Durbin model. We found that: (1) green finance, import trade, outward foreign direct investment (OFDI), and regional innovation capability can promote regional green technology innovation, while inward foreign direct investment (IFDI) has an inhibitory effect on the innovation; (2) the interaction of green finance, international technology spillovers, and regional innovation capacity positively impacts green technology innovation; (3) green finance and international technology spillovers can promote green technology innovation by promoting regional innovation capabilities; (4) and green technology innovations have spatial spillover effects, and innovations in one region can promote the growth of green technologies in adjacent regions. This study provides a reference not only for China but also for other developing countries to promote green technology advancement and achieve sustainable development goals.

Using data on green patents filed at the European Patent Office from 1980 to 1984, this paper investigates the effect of increasing government R&D budget on green technology spillovers. Spillovers are measured with patent forward citations over the period 1981–1988. The level of government R&D budget is instrumented leveraging the unexpected occurrence of the Chernobyl nuclear accident—that exogenously pushed governments to reduce their energy-related R&D budgets—in a difference in differences setting. 2SLS results show that a 10% increase in government R&D increases by some 0.7% the number of citations received by green patents. Although positive and significant, the small magnitude of the estimated elasticity suggests that government R&D takes time to let innovation spillovers from green technologies to materialize with some relevance. Interestingly, increasing government R&D expenditures fosters green technology spillovers across traditional (non-green) fields and enlarges the technological breadth of inventions citing green patents. Overall, I conclude that government R&D fosters green knowledge spillovers, accelerates hybridization processes and favors technological diversification around green technologies. However, these positive effects seem to materialize at a slow pace.

Over the years, foreign direct investment (FDI) has not only promoted rapid economic growth in China, but also affected the country’s environmental quality through technology spillover. This paper tests the variables that may affect the ability of green innovation by using the Granger causality test. It extracts the variables passed the test as input variables, selects the number of patents as output variable, and evaluates the efficiency of various provinces in mainland China by examining their yearly technological progress variables. At the same time, technological progress is defined and divided into capital and environmental factors, and then panel data using the variable coefficients model was used to fit influencing factors to obtain impact coefficients of capital and environment. On this basis, this paper makes the determination of membership to replace the general sense of ‘threshold’ value by using fuzzy theory and proposes the concept of the ‘comprehensive threshold’ of economic development and environmental protection. The results show that less than a quarter of China’s provinces have crossed the comprehensive threshold. Finally, based on the conclusions of quantitative analysis, some suggestions are proposed that the Chinese government ought to enact different strategies for the introduction of FDI according to different development situations of different provinces.

We analyse the international impact on carbon emissions from national climate legislation in 111 countries over 1996–2018. We estimate trade-related carbon leakage, or net carbon imports, as the difference between consumption and production emissions. Legislation has had a significant negative and roughly similar impact on both consumption and production emissions. The net impact on trade-related emissions is therefore not statistically significant, neither in the short term (laws passed in the last 3 years) nor the long term (laws older than 3 years). We find a significant negative long-term impact on domestic emissions from laws passed by trade partners. This latter specification corresponds to the traditional definition of carbon leakage. Overall, we conclude that there has been no detrimental effect of climate legislation on international emissions.

Global warming is a key issue that is related to the sustainable development of various countries, and agricultural sectors are particularly vulnerable to the effects of climate change and increasing climate variability. To obtain a better understanding of agricultural greenhouse gas (GHG) emissions, the estimation method proposed by the Intergovernmental Panel on Climate Change was used to estimate agricultural GHG emissions in 31 provinces in China with respect to five factors: agricultural energy consumption, agricultural farmland utilization, crop cultivation, ruminant feeding, and straw burning. To analyze emission reduction strategy interactions as well as the spillover of agricultural technical information between regions, we used the spatial Durbin model and further explored the different channels of technology spillover. The results obtained were as follows: (1) ruminant feeding and straw burning are the major sources of agricultural GHG emissions in China; (2) emission reduction strategies interact in the various regions, and imitation behaviors are increasing; (3) the correlation of agricultural GHG emission reduction in the different regions in China is not only limited to direct imitation behaviors, and it also reflects the spillover of technical information, i.e., agricultural technological progress plays an important role in the regional linkages of agricultural GHG emissions; (4) a shortening of the economic distance facilitates agricultural technology exchanges between regions. Therefore, to reduce agricultural GHG emissions, it is recommended that all regions should establish regional cooperative emission reduction mechanisms via agricultural technical cooperation.

We use newly constructed state-specific data to explore the implications of common modeling choices for measures of research returns. Our results indicate that state-to-state spillover effects are important, that the research and development lag is longer than many studies have allowed, and that misspecification can give rise to significant biases. Across states, the average of the own-state benefit-cost ratios is 21:1, or 32:1 when the spillover benefits to other states are included. These ratios correspond to real internal rates of return of 9% or 10% per annum, much smaller than those typically reported in the literature, partly because we have corrected for a methodological flaw in computing rates of return.

Foreign direct investment (FDI) technology spillovers play an increasingly important role in a host country’s development. Evaluating the positive effect of FDI inflows on green innovation is essential for correct city design. Based on the panel data of 262 cities in China from 2004 to 2018, we first analyzed the impact of FDI technology spillovers on green innovation in Chinese cities and then tested the threshold effect in four absorptive capacity factors: environmental regulation, economic growth, human capital, and industry size. Finally, we compared the time and space of two types of cities crossing the threshold from the perspective of innovative and non-innovative cities. The results show that FDI can significantly promote green innovation in Chinese cities and the promoting effect of FDI on green innovation has nonlinear characteristics, namely, such effects only make sense when absorptive capacity is above the threshold points. Additionally, among the four absorptive capacity factors, the development degrees of innovative cities are ahead of non-innovative cities; in particular, there is a significant difference between them in terms of economic growth. Local governments should develop reasonable policy combination tools according to the absorptive capacity characteristics of different cities to effectively promote the technology spillover effect of FDI and achieve coordinated ecological and economic development.

This paper explores the advantages of international trade and foreign direct investment (FDI), which can be the main factors of transferring technology to economies. More specifically, it seeks the importance of international trade and FDI as the main channels of technology transfer between countries either in a region or at the international level. In this context, relevant spillovers arising from trade and FDI play important roles in achieving economic growth, capital accumulation and economic well-being, providing a path for sustainable development. The main goal of this paper is thus to investigate the possible implementation of regional economic through cooperation in trade and investment in a region such as the Economic Cooperation Organization (ECO). Accordingly, the country members can benefit from spillover effects on their economic growth, as a major factor to appoint sustainable development. The relevant methodology relies on estimation of a panel economic growth model in which we have used the obtained empirical results to assess the effects of trade and FDI spillovers on economic growth over the period 1995–2018. The empirical results have indicated significantly positive effects of the spillovers on economic growth of the ECO country members, as the case study, implying sustainable growth in the long run.

In the context of global value chains, it is becoming increasingly common for foreign‐funded enterprises to participate in local industrial chain activities through shareholding. However, as an external force, do multinational corporations play a balancing role or a collusion role in the production process of enterprises in pollution‐intensive host countries? This study explores whether the participation of foreign capitals will drive pollution‐intensive local enterprises to realize cleaner production and how it works. We employ a staggered DID model to regress the composition of the nature of equity and the degree of cleaner production of listed firms from China. The result shows that foreign ownership can significantly drive cleaner production by promoting green technology innovation and improving the environmental management capability of domestic polluting enterprises. In addition, the stronger the degree of foreign ownership and the higher the R&D investment, the more obvious the promotional effect of foreign investment on cleaner production of local firms. Moreover, the foreign shareholding serves as a more significant element to realize cleaner production when the percentage of funds from Hong Kong, Macao, and Taiwan of China is higher. This study provides new evidence for the classic “pollution halo” hypothesis from the perspective of foreign equity holdings. In the wave of globalization, it remains important for developing countries to learn advanced environmental management concepts and clean production technologies from foreign capital.

Productivity improvements generally are driven by technology innovation and its spillovers. This study explores the role of R&D investment and intermediate input trade in productivity growth using country-industry-level data for 25 advanced and emerging economies. This paper confirms that R&D investment and intermediate input import/export (both intra- and inter-industry) with technologically advanced economies play important roles in productivity growth in non-frontier countries. We further find that the productivity gains of technology spillovers via input trade channels are likely larger for countries/industries where technology converges to the frontier. These findings imply that the recent slowdown in R&D investment and intermediate input trade in some advanced economies may contribute to declining productivity growth. The potential productivity improvements from R&D investment and free trade as well as the importance of domestic capacity in facilitating technology spillovers should be recognized.
