Thoughts on the Law of Automobile Industry Development

Fu Yuwu, Chen Xiumin

Strategic Study of CAE 2019, Volume 21, Issue 3,   Pages 98-102 doi: 10.15302/J-SSCAE-2019.03.019

Abstract:

Automobile industry has accumulated numerous worldwide-accepted laws since its emergence over 130 years ago.China's automobile industry is currently facing a strategic opportunity for industrial transformation and upgrading, so it is necessary to strengthen the research on the laws of development for the automobile industry, thus to avoid any impulsive actions. In this paper, nine laws of development are summarized from the aspects of technology, market, and talent, including the complementary relationship between transformation and upgrading, the characteristics of the capital-, technology-, and labor-intensive industry, the inevitable requirements of innovation and collaboration, etc., thus to guide and promote the healthy and sustainable development of the automobile industry in China.

Industrial water treatment and industrial marine outfalls: Achieving the right balance

Law,Chunyan Tang

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 4,   Pages 472-479 doi: 10.1007/s11705-016-1592-0

Abstract: Industrial water treatment and industrial marine outfalls both function together to reduce the pollutant concentrations in the effluent and mitigate the potential impact on the environment. The former uses environmental treatment technology with energy and material cost considerations, while the latter utilizes the natural assimilation potential of the coastal water environment achievable at the outfall location. Because of their synergistic nature, marine outfalls are now commonly used for the disposal of partially treated domestic and industrial effluents in many coastal cities around the world, with many successful examples of low and acceptable risks to the environment. The objective of this paper is to review their balance from both environmental and economic considerations. We also discuss the end-of-the-pipe and mixing zone approaches for industrial effluents, and give some recommendations particularly for developing countries. Finally, we emphasize that a compulsory and vigorous monitoring program is essential regardless of how the balance is achieved.
