China’s government has enforced a series of renewable energy policies to promote renewable energy development and achieve the dual decarbonization goals. However, there exists great disparity in previous studies on the effectiveness and suitability of renewable energy policies in abating carbon emissions. This study employs a dynamic general equilibrium model and assesses the effectiveness and trade-offs of renewable energy policies in achieving the dual decarbonization goals by 2060 in China. These policies include carbon market (CRP), the reduction of feed-in tariffs (FIT), the reduction of fossil fuel subsidies (FSB), the reduction of renewable energy costs (REC), resource taxes (RTX), and renewable portfolio standards (REP) as well as the mix of these policies. We find that renewable energy policies together could abate China’s CO2 emissions in 2060 by 2.57 billion tons, but their effectiveness is very different. The REC would have the greatest effectiveness in abating CO2 emissions, followed by REP and CRP. Renewable energy policies would cause relatively slight damage to China’s GDP, with the exception of the REC (raising GDP by 1.1713%). Regarding trade-offs, most policies will sacrifice China’s internal and external demand but benefit employment. Renewable energy policies will effectively promote the low-carbon transformation of China’s energy structure.

“…Penelitian atas penerapan pajak karbon di China juga pernah dilakukan. Penelitian ini dilakukan dengan tujuan untuk melihat bagaimana pengaruh terhadap emisi karbon dan terhadap PDB China jika semisal pajak karbon diterapkan di China oleh Cao et.al (Cao et al, 2021). Penelitian tersebut dilakukan dengan menggunakan 8 (delapan) skema tarif pajak karbon yang diterapkan oleh peneliti.…”
Penelitian ini dilakukan dengan tujuan untuk melihat bagaimana tarif dan mekanisme penerapan pajak karbon di Swedia dan Finlandia untuk kemudian dibandingkan dengan rencana penerapannya di Indonesia berdasarkan Undang-Undang Nomor 7 Tahun 2021. Metode penelitian yang digunakan berupa kualitatif deskriptif dengan metode pengumpulan data berupa wawancara dan studi literatur. Hasil penelitian ini menyimpulkan bahwa Swedia, yang memiliki tarif pajak karbon tertinggi di dunia, berhasil menekan emisi karbonnya dan tanpa memberikan dampak negatif bagi perekonomian negaranya. Serupa dengan Finlandia, yang merupakan negara pertama yang menerapkan pajak karbon di dunia, berhasil menekan emisi karbonnya dan tanpa memberikan dampak negatif bagi perekonomian negaranya. Indonesia akan mulai menerapkan pajak karbon sejak April 2022 atas sektor Pembangkit Listrik Tenaga Uap-batu bara, dimana mekanisme yang diterapkan adalah Cap-and-Tax yakni gabungan dari perdagangan karbon dan emisi karbon. Tarif pajak karbon yang diterapkan adalah sama dengan harga karbon di pasar karbon namun tidak boleh kurang dari Rp30 per kilogram CO₂ ekuivalen.
“…The carbon tax rate can significantly affect emission reductions, and governments must set a higher rate to further abate emissions at the national level. However, policymakers favor a moderate tax rate [41].…”
Section: Traditional Policy Effect Of Carbon Taxesmentioning
The major global economies are facing increasing pressure to reduce their carbon emissions. Introducing environmental policy instruments to stimulate green innovation is key to mitigating global warming. We propose a carbon tax design with a typical green innovation orientation that links carbon taxes with the low-carbon technology (LCT) of enterprises and imposes a progressive tax on heterogeneous enterprises with LCT stock to encourage green innovation. This study used a dynamic evolution game model based on the Stackelberg model of heterogeneous enterprises with LCT stock to analyze the green-innovation-inducing effect of unit progressive carbon taxes. A unit progressive carbon tax could encourage enterprises to participate in green innovation, regardless of their initial green innovation willingness. The progressive tax rate was more effective than a fixed rate for stimulating green innovation by all enterprises. There was a marginal diminishing effect of increases in the tax rate. An increase in the innovation cost coefficient of enterprises reduced the green-innovation-inducing effect of the unit progressive carbon tax. Increasing the tax rate was effective only under normal circumstances. A decline in the carbon reduction in enterprises also reduced the green-innovation-inducing effect of the unit progressive carbon tax. Furthermore, increasing the tax rate when the carbon reduction amount was extremely low caused enterprises to abandon green innovation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
