“…According to the National Economic Industry Classification (GB-T4754-2017) [71], "scientific research, technical services and geological exploration industry and information transmission, computer services, and software industry employees" are defined as scientific and technological talents, and Tg is measured by the proportion of the number of scientific and technological talents in the total population of the region at the end of the year. 2 ⃝ Industrial agglomeration (Ig). The formula is shown in Equation ( 6):…”

“…Referring to the existing related research on Pc [72][73][74][75][76], the following five variables were finally selected as control variables: 1 ⃝ Degree of government intervention (Gov), measured by the ratio of local general public budget expenditure to regional GDP. 2 ⃝ Internet level (Inter), expressed as the logarithm of the number of Internet access users. 3 ⃝ Industrial structure (Str), measured by the ratio of value added of secondary and tertiary industries to regional GDP.…”

“…First, the effects of HSR and BCS on Pc were examined separately. Excluding the sample of BCS cities, only the sample of HSR cities and the sample of cities with neither HSR nor with BCS cities are retained, and the coefficients of the DID HSR variable reflect the net effect of HSR on Pc, and the estimation results are illustrated in columns (1), (2), and (3) of Table 7. The coefficient estimates of HSR on Pc, Ci, and Pi are −0.890, −0.055, and −0.834, respectively, which pass the test of significance at the level of 1%, indicating that the implementation of HSR will lead to an average annual PC increase of 0.890 percentage points, and also lead to the average annual Ci and Pi of the city to decrease by 0.055 and 0.834 percentage points, and the HSR has a more obvious impact on reducing the pollution intensity.…”

“…Climate warming and environmental pollution are the two major environmental problems facing the world today, and not only hinder economic growth but also affect people's health [1,2]. According to the Global Carbon Project (2023), in 2022, China, the United States, India, and the EU27 accounted for 31%, 14%, 8%, and 7% of global fossil CO 2 emissions, respectively.…”

“…(1) In terms of research topics, unlike existing studies that analyze the environmental effects of single infrastructure construction, the effect of infrastructure upgrading on Pc is explored, and the possible synergistic effect between transportation infrastructure and digital infrastructure is taken into account, which is a reasonable addition to the existing research results. (2) In terms of identification strategy, based on the exogenous shock of the establishment of the dual pilot, the multiple-period difference-in-differences method was used to systematically assess the magnitude of the effect of infrastructure upgrading on Pc, as well as the specific mechanism of the effect. (3) The "net effect" of the dual pilot policy on Pc, which is different from that of the single pilot policy, was captured, and the heterogeneous impacts of the differences in the characteristics of the cities themselves and the order of policy implementation on Pc were further analyzed.…”

Infrastructure upgrading has an important impact on environmental protection and low-carbon development. Based on the panel data of 277 prefecture-level cities in China from 2005 to 2021, we examined the impact of infrastructure upgrading on the synergistic effect of pollution reduction and carbon reduction (Pc) by using the multiple-period difference-in-differences method. The results show that infrastructure upgrading can achieve Pc. Additionally, compared with resource-based cities, peripheral cities, and central and western cities, the impact of infrastructure upgrading on Pc is more significant in non-resource-based cities, central cities, and eastern cities. Meanwhile, infrastructure upgrading can promote Pc by promoting scientific and technological talent agglomeration (Tg) and industrial agglomeration (Ig). Finally, the policy of synergy analysis shows that compared with the single pilot cities, the dual pilot cities have a more obvious effect on Pc, and becoming first high-speed rail (HSR) cities and then becoming “Broadband China” strategy (BCS) cities has a stronger effect on Pc. Therefore, to effectively alleviate the dual environmental pressures of pollution reduction and carbon reduction, emphasis should be placed on promoting the common development of transportation infrastructure and digital infrastructure.
