Exploring the influencing factors of carbon neutralization in Chinese manufacturing enterprises

One of the key issues facing the government in achieving carbon neutrality is what methods can be used to effectively reduce carbon emissions. Taking manufacturing enterprises as an example, this paper studies the carbon emission reduction effects of green technology innovation subsidy (GIS), carbon tax (CT), and carbon emission trading (CET). Under the background of social welfare and carbon emission reduction efficiency, we get the results of optimal carbon emission reduction measures in different environments. The results are as follows: (1) In the initial and mature stage of green technology innovation, GIS is the best choice to improve the degree of green manufacturing and maximize social welfare. CT and CET are the best choice to obtain the highest SE (carbon emission reduction efficiency). (2) In the transitional stage, CET and CT can promote the maturity of green technology. However, with the maturity of green technology, the promotion of green technology has weakened. CT is the best choice to achieve the highest SE. (3) When the carbon tax or carbon trading price is at a high or low level, raising the tax rate or carbon trading price can increase the income of enterprises. Therefore, the government should take measures according to the objectives of different stages. When the goal is to maximize social benefits, GIS is the best choice in the initial stage and transition stage, and CET or CT is the best choice in the transition stage. In the initial stage and fertilization stage, when the highest SE, CT, or CET is the best choice, while in the transition stage, CT is the best choice.

     

长江产业带投资条件比较与综合分等评价

将长江干流沿江地区建设成具有强大经济实力的国家级产业密集带是９０年代国家调整宏观经济发展布局的重大战略举措。在大规模投资开发过程中如何按照各地投资环境特点，选择最佳的投资区位和适宜的投资方向是十分重要的。本文选取了能基本反映研究地区投资环境状况的基础设施条件，经济发展水平，科教发达程度，主要资源赋存和区域环境质量５类因素共１４项指标，以产业带范围内的４０个地市为地域单元，对产业带内部的投资环境条件

中国黄土高原的形成过程与整治研究

从黄土高原的形成过程,黄土-古土壤性征的对比,孢粉、石器、历史、地理以及水土流失的定位观测资料,说明目前黄土高原的严重水土流失是人类破坏植被,不合理利用土地和直接毁灭土壤透水和抗冲能力的结果,而不是一个天然的地质过程。以“28字方略”为中心的水土保持措施是开发整治黄土高原水土资源和治理黄河的根本。
