As this newspaper went to press, Facebook was about to become a public
company. Mining machinery manufacturing industry()
will be able to achieve the goal of low carbon environmental protection, which
will not only save energy, save materials, environmental friendly, but also
reuse mining waste machinery products will get improved and make breakthrough.
The issue of safety is a tougher problem. Oligopolies that generate fat
profit margins and leave banks with little incentive to take risk actually suit
regulators. They have a built-in safety cushion; and if it comes at a cost to
consumers, so be it.
In most retail revolutions politicians have had to do
little other than move out of the way. But banks are different: their central
role in the economy means that governments have to make sure that they are both
accessible and safe.
In terms of access, some worry that as banking moves
further online, the old, the poor and the computer-illiterate will be excluded
from the financial system. But the simple, low-cost mobile-banking systems that
operate in countries such as Kenya, India or Brazil suggest otherwise.
But
look closer and the picture changes (see article). Mark Zuckerberg, Facebook’s
young founder, resisted going public for as long as he could, not least because
so many heads of listed companies advised him to. He is taking the plunge only
because American law requires any firm with more than a certain number of
shareholders to publish quarterly accounts just as if it were listed. Like
Google before it, Facebook has structured itself more like a private firm than a
public one: Mr Zuckerberg will keep most of the voting rights, for
example.
On the other hand, finance has seen plenty of dramas over the years.
But one thing has remained constant for a century at least: the branch banking
system. Across most of Europe a handful of large banks, each with thousands of
branches, stand astride their national markets.
Now an upheaval is coming,
driven by technological changes—the growth of internet usage on smartphones, the
rise of “big data” computer processing and the increasing willingness of
customers to do complicated things online.
When a higher requirement to
crushing degree, crushing operations of cone crusher are often composed of
several crushers to complete the mechanical crushing system. In the system,
materials should get through all crushers, and its particle size is gradually
reduced, and finally reach the required particle size.
