交通部门是中国最重要的碳排放源之一,交通电动化对实现双碳目标至关重要。本文以中国纯电动汽车消费为例,采集2017年1月至2020年11月中国31个省份(因数据缺失,不包含港澳台地区)充电桩数量及电动汽车销量数据构建面板固定效应模型和门槛效益模型,实证分析了不同类型公共充电基础设施对不同用途纯电动汽车购买的影响,以及不同地区温度对销量影响的门槛效应。研究发现公共充电桩数量增加1%,纯电动汽车购买量显著增加0.85%,其中出租租赁用途纯电动汽车销量显著增加1.57%。直流公共充电桩对纯电动汽车购买的影响远大于交流公共充电桩,并对不同用途的电动汽车存在异质性影响。此外,在气温更低的地方公共充电桩对纯电动汽车购买的影响更大,其显著门槛值为15摄氏度,且气温对出租租赁汽车的影响比非营业用途更大。政策制定者应合理考虑公共充电桩等基础设施的增设布局以保障电动汽车的续航能力,从而促进交通运输部门的脱碳进程。 相似文献

ABSTRACTSince the Belt and Road Initiative (BRI) has been implemented for five years, it is time to ask whether the BRI contributes to Belt and Road (BR) countries’ economic growth, and how are the five elements of connectivity implemented between China and its partner countries since the BRI was proposed. This study focuses on the development of the five elements of connectivity between China and the BR countries from 2008 to 2017 using a comprehensive connectivity index extracted from principle component analysis, and then investigating if the connectivity has contributed to the economic growth of the BR countries with quantitative analysis of the fixed effect econometrical model. It is found that Russia, South Korea, and Singapore presented the top three levels of connectivity with China with regard to the overall connectivity index, varying from 1.4 to 2.4. Madagascar and Panama have the lowest level of connectivity with China, with values of ?0.8 to ?1.1. The result of the fixed effect model shows that the connectivity of the BR countries with China contributes to their economic growth. This provides quantitative evidence that the connectivity between BR countries and China has a significant influence on the economic growth of those countries. 相似文献

This paper uses a new approach to estimate how government expenditures affect the growth rate of real GDP. They affect the growth rate through three channels ‐ total factor productivity, investment and aggregate demand. We find that apart from government investment, all government expenditures have negative marginal effects on productivity and GDP growth. In particular, a 1 percentage point increase in the share of government consumption in GDP reduces the equilibrium GDP growth rate by 0.216 percentage points, while the same increase in government investment raises the growth rate by 0.167 percentage points. This suggests that a reallocation of 1 percentage point of government consumption to government investment can raise the growth rate by 0.38 percentage points. 相似文献

In this paper I examine the effects of overpayment and form of financing on bidding firms' stock returns and the determinants of the form of financing in mergers and tender offers. First, I find that in the 1980s potential overpayments to target shareholders and the form of financing are important for explaining cross-sectional differences in bidding firms' returns upon the announcement of mergers or tender offers. Second, I find that in the 1980s cash offers were likely to be chosen by cash-rich firms relative to their industry, and stock exchange offers were likely to be chosen by normal cash-generating firms relative to their industry. The latter finding is consistent with the pecking order hypothesis and casts doubt on recent signaling explanations of the form of financing. 相似文献
