央视网消息:此次全国经济普查还揭示了哪些未来趋势呢?一起来看中国之声评论员许树泽的分析。

中国之声评论员 许树泽:根据公报披露的数据,全国所有的第二产业和第三产业,一共收入了295万亿元。为了得到这笔收入,公司一共投入了290万亿元的净资产(914万亿元资产,624万亿元负债)。翻译一下,在中国做生意,撇开农业不谈,投入一块钱资本金,大概一年可以得到一块钱收入。利润率按照4%来粗略计算,在中国做生意,能真实赚到投入资本的4%,这是市场竞争环境下,参与者基本都能得到的回报水平。上市公司大概能得到10%左右利润,只有极少数优秀的企业能得到15-20%的回报。

东部地区的法人单位和从业人员数所占的比例都在下降,而中部和西部地区正在上升。经济的地区差异在缓慢变小。东部地区正在变成一个消费中心,而大量的生产和就业在往中西部地区迁移,中西部正在变成一个巨大的生产中心和就业中心。人口,尤其是就业人口流动的方向,是一个非常重要的经济先行指标,可以为求职就业者指引方向。

研发投入的力量越来越大。整个经济平均投入研发经费占比达到2.2%,相比上次统计,中国的发明专利增长了80%。

企业数量变多的同时,个体经营户的数量也在大幅增长。过去人们必须依赖公司,因为公司形式能够发挥规模效应降低成本。而当未来5G时代到来,通过移动互联网,个人可以发挥比公司更强的低成本优势。由于更高效便捷的协作革命出现和更完善的基础设施的覆盖,个人的经济能力将可能被全面解放出来,属于个人的时代已经全面到来!

 “We can use color in powerful ways to enhance the meaning and clarity of data displays, but only when we understand how it works, what it does well, and how to avoid problems that often arise when it’s used improperly. My expertise in color, which focuses almost exclusively on its proper use in data displays, is practical in nature. My grasp of color theory—a fairly complex fi eld of study—does not run deep. This article is intended for people like me who must understand color insofar as it applies to quantitative data displays. We are concerned with the practical use of color, not its use for artistic expression. Becoming familiar with a few simple rules about color and its use will serve us well.

图中多少种颜色,显得太多了,《Good Charts》认为是8种,当然会因人因情况有差异,不过颜色的数量的确是一个值得讨论的问题。
