中国电子废弃物循环利用产业化问题及其对策 总被引：20，自引：0，他引：20
电子信息技术产业已经成为我国发展最快的产业之一,由此产生的电子废弃物也快速增长,未来10年～20年将是电子废弃物增长的新高峰.中国电子废弃物循环利用产业发展仍存在许多亟待解决的问题,如电子废弃物处理产业投资不足、管理体制混乱、技术水平低、缺乏健全的产业政策体系、二手市场过大等.本文在分析中国电子废弃物现状及其循环利用产业存在问题的基础上提出如下对策建议:完善电子废弃物处理的法律法规体系;制定鼓励政策,促进电子废弃物循环利用产业化;推行"生产者延伸责任制"下的企业跟踪回收模式;引入市场竞争机制,实现电子废弃物循环利用产业的规模化和专业化;实施电子废弃物回收处理许可证制度;控制国外电子废弃物进入中国,整顿国内电子废弃物回收与处理市场;加强循环经济意识和电子废弃物回收利用的舆论宣传力度.可以预见,中国电子废弃物循环利用产业的发展将有效解决我国电子废弃物问题,对我国资源短缺问题也有着极大的缓解作用. 相似文献

电子废弃物回收企业经济补偿机制的系统动力学研究 总被引：1，自引：0，他引：1
提出了利用系统动力学建模的方法来分析电子废弃物回收企业经济补偿机制,并依此对相关改革政策进行探讨。分析结果表明,此补偿机制涉及到生产商、消费者、政府等相关主体及相关政策,回收利用扶助资金、转化后的资源收益、财政征收的税费共同构成电子废弃物回收企业的经济补偿来源。改革政策的推行和完善应以经济补偿机制为基础并系统考量。最后,以广东省为例进行了实证研究。 相似文献

现行税法规定,纳税人为销售货物出租出借包装物而收取的押金,无论包装物周转使用期限长短,超过一年（含一年）以上仍不退还的均并入销售额征税;还有,对销售除啤酒、黄酒以外的其他酒类产品收取的包装物押金,无论是否返还以及会计上如何核算,均应并入当期销售额征税。相关税法明确规定了征收的税种、计税时间,税额的计算等。但如何编制会计分录,即借、贷方的会计科目等如何,并没给出具体规定,这样会计实务中很易出错。本文依据税法对应税消费品包装物押金计税的基本原则、不同消费品包装物押金的处理、逾期包装物押金的会计处理等进行探诎主要用实例说明“逾期”包装物押金的会计处理,以供参考。 相似文献

受"发展循环经济"的导向作用,当前自然资源开发利用制度中产权、价格、税费制度虽在一定程度上激励经济当事人合理开发利用自然资源,但仍然存在产权不明晰、资源价值没有得到体现及利益分配不公等问题。所以,在建立资源的有偿使用制度和补偿机制时,应该要考虑建立长效的自然资源开发利用激励机制,如明晰自然资源产权,实行自然资源开发权拍卖制度,建立开发权交易市场;建立自然资源开发的资源税费和生态环境税费体系;建立押金抵押返还政策等。 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

Prof. SUN Changpu from the CAS Institute of Theoretical Physics coworkers from University of Basel in Switzerland have worked out a way - at least in theory - to split a beam of molecules according to their chirality. The technique involves passing the molecules through three different laser beams is similar to the famous Stern-Gerlach effect whereby a beam of atoms passing through a magnetic field is split in two according to the atoms' spin states 《中国科学院院刊(英文版)》2008,22(1):23-23
