工程优化法管理电厂

背景链接大港发电厂始建于20世纪70年代,总装机容量131.4万千瓦,分别为四台32.85万千瓦的机组,分两期建成,其中一期两台原为燃油(燃气)机组,分别于1978年和1979年投产发电,进入90年代以后,随着燃油价格的不断上涨,发电成本越来越高,因此,机组基本处于长期停备状态。2003年3月6日,原国家经贸委正式批准一期油机改造,并列入第六批国债重点技术改造项目,2003年4月9日改造工程正式启动,2004年12月9日2号机组移交生产,1号机组于2005年5月份投产发电。二期两台燃煤机组分别于1990年和1991年投产发电,目前机组运行正常。一期技改工程竣工后,大港发…

On the impact of financial development on income distribution: time-series evidence

Financial market development is said to have equalizing or unequalizing effects on income distribution. Previous research used cross-sectional and panel data and provided mixed results. Suspecting that they suffer from aggregation bias, we adhere to time-series data and error-correction modeling technique and address the issue one more time in each of the 17 countries for which we have time-series data. In 10 counties, short-run effects of financial market development on income distribution were found to be equalizing. In five countries, the effects were unequalizing. However, the equalizing effects lasted into the long run only in three countries of Denmark, Kenya and Turkey.     

The S-Curve： China versus Its Major Trading Partners

China has been accused of manipulating its currency to gain international competitiveness and enjoy a trade surplus. The S-Curve is a hypothesis that could be used to test the depreciation. It claims that while future effectiveness of currency devaluation or values of the trade balance and current exchange rate are positively correlated, the past values of the trade balance and current exchange rate are negatively correlated. While China＇s aggregate trade flows with the rest of the world conforms to the S-Curve hypothesis, disaggregating trade flows by trading partner reveals that not all partners are affected equally by devaluation. Indeed, trade with 8 out of the 24 partners does not support the S-Curve hypothesis.     

The J-curve: evidence from commodity trade between UK and China

China is often accused of manipulating its currency to gain international competitiveness. Previous studies have tried to address this issue by investigating the impact of yuan depreciation on China’s trade balance. Not only have they failed to establish the link between the Chinese exchange rate and its trade balance with the rest of the world but also between China and her major trading partners. In this article, we consider the China–UK trade balance and disaggregate their trade flows by commodity. Out of the 47 industries considered, we show that the real depreciation has favourable short-run effects in most industries. However, the short-run effects last into the long run only in seven cases.     

人力资本跨部门流动对经济增长和社会福利的影响

本文将人力资本跨部门流动引入带外部性的UzawaLucas模型,研究发现:人力资本持续不断地从物质生产部门转移到教育部门一定可以加快人力资本的积累速度;然而,快速的人力资本积累不一定都能促进经济增长、也不一定都能提升社会的整体福利水平。因此,政府发展教育的规模和速度应当和经济发展阶段相适宜。
