The uniform enterprise income tax reform in China

In China, the income tax of enterprise is very different between foreign funded enterprises and other domestic enterprises. It is believed that this discrimination is harmful to the entire economy. So there is a reform in the tax system to build a uniform enterprise income tax. This is a significant reform in China＇s tax system, so every decision about this have to count the cost and the benefit carefully. The author has introduced the Computable General Equilibrium （CGE） to simulate this new tax system and value its benefit and cost. There are two different models in the paper; they are of different assumptions and for different purposes. Model I is a static CGE model and model II is a Ramsey Dynamic model. The static model is mainly used for comparative static approach to examine how the tax reform will change the endogenous variables. According to the results of the model, more goods will be produced by both of the DFEs and FIEs after the tax reform in the medium and low tax effective tax rate situations. If the nominal tax rates decrease 24.24% （from 33% to 25%）, the enterprise income tax will only reduce 19.36% and the total tax revenue will only reduce 1.911%. The dynamic model will concentrate on the costs and benefits during the transition. From the results of the model, a lower tax rate will increase the level of investment, capital stock, capital prices, wage rate and also the growth rates through transition. If the capital tax rates are changed gradually, the fluctuating of transition will be smoothed a little.     

On the mechanism of international technology diffusion for energy technological progress

As a needed methodological complement to the existing large-scale complex policy modelling for energy technology diffusion, this paper contributes to an analytical exposition of the fundamental mechanism of international technology diffusion (ITD) for energy technological progress. We offer two different and complementary perspectives to explore the dynamics of energy technology diffusion and progress. We first develop a Solow-type efficiency-improving model of energy technological progress which is described by improvements in primary energy-augmenting efficiency. We further provide a Romer-type variety-expanding model of energy technological progress which is represented by the expansion of differentiated varieties of primary energy technology blueprints. Analysis based on two different models reaches consistent results: there are potential forces in the world economy – working through ITD – that pull individual countries to advance energy technology, ensuring a cross-country convergence in the growth rates of energy technology in the balanced growth path. While ITD plays a role in a cross-country convergence in technological growth rates, cross-country differences in the efficiency of undertaking indigenous research and the capacity of absorbing foreign technology spillovers would lead to a cross-country divergence in the absolute levels of energy technology.     

Scenario of China Reaching Carbon Peaking ahead of Schedule and Its Effect on Macro Economy

At the 75th session of the United Nations General Assembly (UNGA) in 2020, China put forward the goal of peaking carbon dioxide emissions by 2030 and achieving carbon neutrality by 2060, a move to lead global response to climate change that has attracted wide attention and hot comments at home and abroad. Therefore, it is of great practical significance and academic value to explore ways of achieving carbon peaking ahead of schedule and study the macroeconomic effect. This paper, based on Energy, Environment and Economy recursive dynamic computable general equilibrium model (TECGE), a dynamic computable general equilibrium model, carries out a quantitative analysis of the effect of strengthening carbon peaking commitment on China’s future macro economy. By setting up four scenarios, namely carbon peaking of 10.8 billion tons, 10.7 billion tons, 10.58 billion tons and 10.36 billion tons in 2030, 2027, 2025, and 2023, it examines the effects of carbon peaking ahead of schedule and carbon peaking in 2030 on macro economy. The findings show that, compared with the 2030 benchmark, the more ahead of schedule carbon peaking is achieved, the higher the carbon tax prices, and that though GDP and other macroeconomic variables, such as aggregate consumption, aggregate imports and exports decline, the share of the tertiary industry increases. That is, the more ahead of schedule carbon peaking is achieved, the more macroeconomic variables decline, and the more the share of the tertiary industry rises. This paper, using computable general equilibrium (CGE) model to conduct a quantitative analysis of the macroeconomic effect, makes policy recommendations for carbon peaking ahead of schedule and high-quality economic development.     

ICT-specific technological progress in the United Kingdom

This paper analyses the impact of rapid technological change in the information and communications technology (ICT) sector on economic growth in the United Kingdom. We find that technological progress specific to the ICT sector accounts for around 20–30% of long-run labor productivity growth. We demonstrate that a permanent increase in the growth rate of ICT-specific technological progress will increase the investment expenditure share of GDP but lower the aggregate depreciation rate, while an increase in the return to investment in ICT will increase both the expenditure share and the depreciation rate.     

基于可计算的一般均衡模型的我国碳税政策“双重红利”研究

建立了分析我国减少二氧化碳排放而征收碳税的可计算的一般均衡模型,分析碳税政策的双重红利。结果显示:为减少二氧化碳排放而征收碳税,对社会经济变量将造成一定的负面影响。保持财政中性,在征收碳税的时候,减少居民或者企业间接税,都可以在减少二氧化碳排放量的同时提高社会福利或者保持社会福利变化不大,实现碳税的双重红利。但是在保持财政中性,在征收碳税的同时减少企业所得税,虽然减少了二氧化碳排放量,居民的社会福利却有了更大程度的下降。

Green technological progress,agricultural modernization,and wage inequality: Lessons from China

Green technological progress (GTP) is crucial for environmental protection and economic growth in China. Over the past decades, China made huge GTP which exerts a far-reaching consequence on economic and social development. However, a paucity of research investigates the distributional effect of GTP. Meanwhile, we incorporate agricultural producer service sector into a three-sector general equilibrium model to reflect the modernization of small-scale agriculture. The agricultural producer service sector that acts as an intermediate sector can facilitate the utilization of intermediate inputs indirectly. To desalinate this process, a two-layer vertical production structure is established: parts of manufacturing goods are utilized by the service sector, outputs of which are intermediate inputs that could substitute labor in agriculture. Theoretical analysis shows that GTP increases both wage of skilled labor and unskilled labor. Nevertheless, GTP generates a greater impact on the wage of skilled labor than unskilled labor, leading to widening income disparity. Then, we examine the impact of GTP on wage inequality using a balanced panel data covering 30 provincial units in China during 2000–2019. In line with our theoretical conjecture, we find strong supportive evidences that GTP significantly widens the wage inequality.     

中国农业发展方式的评价

本文运用非参数的莫氏（Malmquist）指数法,研究了1978-2009年期间中国农业全要素生产率增长、构成的时序特征及其农业增长方式转变的绩效。结果表明,中国农业全要素生产率在1978-2009年的31年间,年均增长率为26%,农业全要素生产率的增长主要来自技术进步,中国农业仍然保持粗放型发展方式,目前主要处于低度粗放型阶段。在未来农业生产方式转变中,通过技术进步、劳动者素质和生态环境保护来提高生产要素的使用效率,实现农业发展方式的转变。     

碳税对我国区域经济发展的影响

从基本的投入-产出模型出发,运用2007年地区投入产出表以及各省统计数据,按照消费者责任原则,在考虑地区间贸易因素的情况下,对我国东、中、西部样本地区的碳排放量进行了估算,得出不同碳税水平下样本地区的税负水平。结果表明:与中、西部地区相比,东部发达地区大部分产业部门的碳排放强度较低,生产技术水平相对较高;不同碳税水平下各地区税负有较大差别;随着碳税水平的提高,地区(如西部)越不发达,税负增幅越大,所承受的税负越重,进而导致区域经济发展不平衡。为此,合理选择碳税水平对统筹我国区域经济协调发展非常必要。     

中国碳减排政策的模拟分析——基于中国能源CGE模型的研究

通过构建中国能源CGE模型,在模型中引入碳税和碳排放变量,细化出能源部门,并将煤炭、石油和天然气三种主要能源作为生产要素,设定节能减排基准情景,针对碳减排、碳税和能源结构调整这三个不同的能源政策对经济发展以及碳排放的冲击效果进行了模拟分析.模拟结果表明,单一的能源政策总有不足之处,要么减排效果欠佳,要么严重制约经济发展,因此国家应该将减排政策系统化,构造一个适应现实需要的低碳经济政策体系.

Recycling of carbon/energy taxes and the labor market

This paper provides a quantitative assessmet of a cost shift from labor to energy by means of a carbon/energy tax. The analysis utilizes a general equilibrium model for the European Community, placing the emphasis on the modeling of labor supply. The paper highlights the importance of the feedback from an induced increase in labor demand to wage formation. It shows that the goals of CO₂ reduction and improved employment are complementary, provided the reduction in labor costs financed by the carbon/energy tax is not offset by increased wage claims. Under this condition, reduced CO₂ is consistent with an increase in GDP.     

碳税征收对经济增长与产业结构影响的实证分析

征收碳税已成为众多国家推动低碳经济发展的重要经济措施之一。为了检验征收碳税对中国经济增长可能造成的影响,对征收碳税与经济增长的关系进行实证分析,得出以下结论:征收碳税对经济增长的影响存在显著的地域和行业差异,在较低强度的碳税政策下,碳税对中东部地区大部分省份的经济增长有促进作用,但阻碍中西部地区一些省份的经济增长;同时,征收碳税对大多数行业的发展起推动作用,却不利于少数行业的发展。     

Reconciling Economic Growth and Carbon Mitigation: Challenges and Policy Options in China

As the biggest carbon emitter in the world, China is facing tremendous pressure domestically and internationally. To promote the international efforts to tackle climate change, the Chinese government announced its 2020 carbon intensity target and is actively taking part in the international climate negotiations. In this paper, we review some of the climate burden-sharing proposals raised by Chinese scholars to shed some light on China's perspective on the post-Kyoto climate architecture. Then we summarize China's current pollution abatement policies and measures, and analyze some potential policy instruments for China to reconcile its future economic growth and carbon mitigation, as well as some practical design and enforcement issues to be considered for the near term.     

环境保护税对经济和碳排放影响研究——以江苏省为例

环境保护税的征收,有效减少了污染物排放,同时也会对经济和碳排放产生一定影响。通过构建包含环境保护税模块的CGE模型和江苏省2018年环境社会核算矩阵,模拟分析不同环境保护税税率对江苏省经济发展和碳排放的影响。研究发现:(1)征收环境保护税会给江苏省经济带来负面影响,但影响程度较小,当征收税率上升时,江苏省GDP、出口、省际调出等会下降,而居民和地方政府收入几乎没有变化。(2)环境保护税税率上升时,不仅会增加环境保护税收入,还会减少江苏省碳排放水平。(3)对于大多数行业,环境保护税税率上升会造成行业产出下降,但是对于污染物排放强度较低的行业,行业产出会上升,碳排放会增加。(4)为了更好地完成碳减排目标,建议江苏省可以适度增加环境保护税税率或加征碳税,对于污染物排放浓度较低的行业,可以采取补贴措施鼓励发展;对于污染物排放强度较高的行业,要推动转型升级,降低排放强度。

梳理了中部地区吸收利用FDI的现状和特征,计算出了中部的TFP(全要素生产率),并以此作为技术进步的衡量指标,构建VAR模型对FDI和TFP的相关性进行实证分析.结果表明,短期内FDI对中部地区的技术进步有一定的促进作用,但长期来看促进作用并不十分显著.中部地区在吸收利用FDI过程中要引导技术引进,加强自主创新;创造公平环境,扶持本土企业;鼓励中外合资,强化技术合作.     

Influence of Technology Change on High-Quality Economic Development in China

Since the implementation of the reform and opening up policy, rapid growth has been witnessed in the Chinese economy, thanks to the introduced technological progress as well as the institutional advantages of the country. However, while this exogenous technological progress promotes economic growth quantitatively, it is, unfortunately, not conducive to the improvement of the quality of the economy. Structural imbalances have thus been produced, which hinder the high-quality development of the economy of the country. Besides, by way of the “supply and demand rebalance mechanism,” “resource optimized allocation mechanism,” and “new and old kinetic energy conversion mechanism,” original technological progress can effectively push forward the quality change, efficiency change and dynamic change in the economy, thereby promoting the innovation, coordination, greenness and openness as well as the shared development of the economy. Therefore, the current technological transformation in China needs to change from the second stage—the stage of transition from the introduced technological progress mode to the original technological progress mode then to the third stage—the stage mainly based on the original technological progress, which is the key to the successful transformation of the Chinese economy from the high-speed growth phase to the high-quality development phase.     

Measuring the welfare effects of tax changes using the LES: An application to a carbon tax

This paper explores the use of a parametric approach to the measurement of compensating and equivalent variations resulting from price changes. The approach is based on the application of the Linear Expenditure System (LES) to each of a range of household income groups, rather than being based on a representative consumer. The method is then used to examine the distributional effects of a carbon tax, designed to reduce carbon dioxide emissions. The price changes resulting from a carbon tax depend on the carbon intensities of each good, which depend in turn on the nature of inter-industry transactions (the input-output matrix). The use of transfer payments to compensate for adverse distributional effects of a carbon tax is investigated, using social welfare functions based on equivalent incomes.
