Allocating and taxing rights to state-owned minerals

Is Indonesia using the most effective possible strategies to derive revenue from its mineral resources? Auctions and work program bidding are the main ways of allocating mineral leases. In addition to the company taxes applied to all companies, governments can raise revenue from minerals owned by the state through auctions, royalties and rent taxes paid by private firms, and through dividends from state-owned firms. Indonesia uses work program bidding to allocate leases, and its production-sharing contracts are roughly equivalent to a rent tax at a high rate. This paper considers these options for raising revenues from mineral resources. It argues that efficiency and government revenue would both be increased if Indonesia relaxed direct controls on the operations of mining companies, and allocated leases by means of auctions, combined with a much lower rate of rent tax or, better still, a royalty.

我国垃圾焚烧发电技术创新的路径分析

文章分析了技术创新的路径与垃圾焚烧发电技术创新环境、条件,认为目前我国不具备垃圾焚烧发电技术自主创新的条件,只具备模仿创新的条件.因此,当前我国垃圾焚烧发电技术创新路径应是以模仿创新为主,并逐渐向自主创新转变.     

Managing solid waste in small hotels

Collectively, small hotels constitute a significant solid waste management (SWM) problem. Little research has focused on the SWM practices of small hotels. In the United Kingdom, much of the solid waste generated by small hotels goes to landfill. This study uses a constructionist approach to investigate SWM issues in small hotels in a local authority in Wales and examines the role of the public sector in helping small hotels manage their solid waste effectively. The results revealed that only a minority of small hotels were considering the adoption of sustainable SWM practices, either because hoteliers felt negatively about sustainable SWM alternatives or perceived challenges – an issue which necessitates government intervention. At the time of this study, the public sector provided only very modest services to enhance SWM practices. This study proposes a best practice model for the public sector to encourage small hotels to manage their solid waste effectively, in order to reduce or even eliminate waste for landfill. Local authorities' support is required to make waste management hierarchy options more accessible to small hotels and should incentivise better waste management through increasing the gap between the costs of landfill and recycling waste.     

酸性蚀刻废液中铜的形态分布及电化学行为

在氯化物体系中，Cu^＋、Cu^2＋均能与Cl^-形成多种形态的配合物，存在形态及分布与溶液中各离子浓度有关。由于各种配合物的稳定性不同，致使Cu^＋、Cu^2＋氯化物的溶解度及电极电位也不同。对酸性蚀刻废液中铜的存在形态、电化学行为、以及采用隔膜电解法回收工艺的可行性进行了分析。
