| Summary/Abstract |
The renewable energy targets put forward by the Chinese government need comprehensive incentive schemes. This paper uses a multi-regional CGE model to evaluate two types of renewable support schemes; a subsidy scheme like a feed-in tariff (FIT) with a direct price impact for final consumers and a subsidy scheme without any price impact. We assess the CO2 consequences of both approaches, as well as their impact on economic activity in terms of GDP, industrial structure, electricity generation structure, and regional final demand elasticities of electricity. We find that a support scheme with price impact is much more effective in reducing CO2 emissions while the difference in GDP between the two policies is small. We estimate that the price implications of the support scheme allow for an additional emissions reduction of 113 Mt CO2—or 0.07% of total emissions—in China during 2020–2035. The support scheme with a price impact does not lead to a negative impact on the Chinese economy although there are significant differences among regions. In addition, while the whole country faces an approximately unitary electricity elasticity demand, we find significant differences in electricity demand elasticities among Chinese regions.

| Summary/Abstract |
The aim of this study is to analyze the effect that the Energy Tax Directive reform proposed in 2011 would have, if implemented, on the level of prices in the different sectors of the 27 countries of the European Union. We apply a multiregional and multisectoral model of trade flows that takes into account all the intersectoral and intercountry interdependences in the production processes. Using the World Input–Output Database we perform two different simulations. The first one considers the tax changes proposed by the reform; the second one shows the impact the reform would have entailed if it were applied also to sectors belonging to the European Trade System. The main finding of the first simulation shows that the new energy tax regime would have had a low economic cost in terms of impact on prices (less than 1% in all the countries). So, the concerns about competitiveness do not find empirical support in our results, suggesting the need for further analyses to find out the reasons that caused the failure of a reform that was an important step to introduce a taxation explicitly linked to CO2 emissions. The second simulation, however, leads to strongly different results, pointing out the relevance of maintaining significant economic incentives to reduce carbon emissions for the European Trade System sectors, by improving the emission market performance or by applying carbon taxation also to these sectors.
