一 | India and emerging market economies (EMEs) will gain “substantially,” reckoned experts, as Japan-based Nomura Holdings predicts “multiple recessions” for the world’s major economies over the next 12 months.,Nomura Holdings on Monday noted that the US, Eurozone, the UK, Japan, South Korea, Australia, and Canada will fall into recession amid tightening government policies and rising living costs.,“A recession in developed countries can result in heightened interest of Foreign Portfolio Investors towards emerging markets, including India, which is the fastest-growing major economy in the world”, Pranav Haldea, managing director of Prime Database, told Sputnik.,Haldea blames the US Fed rate hike aimed at controlling the rising living costs for the current capital outflow from emerging markets, saying interest rates in the US have a huge bearing on FPI flows.,Foreign investors dumped Indian shares worth $6.4 billion in June — the highest net outflow in over two years. Foreign investors withdrew $27.9 billion from Indian equities in the first six months of 2022.,“Once the current rate hike cycle shows signs of abating, FPIs shall again look at emerging markets with renewed interest”, Haldea reckoned.,Economists observe Fed missteps such as the delayed response to inflation, which the latter labeled “transitory” until March this year, hamper economic activity in the US. The US recorded 8.6 percent inflation in May, the highest in four decades.,Massive inflationary pressure is also hindering growth in European economies such as Germany, Spain, and France, which registered 7.6, 10, and 5.2 percent price rises in May, respectively. Inflation in the UK is running at 9.1 percent.,US Unlikely to Avoid Severe Recession if Fed Hikes Interest Rates Too Quickly to Cool Inflation2 July, 02:42 GMT,Economists warn of spreading high inflation beyond commodities to services items, rentals, and wages.,Nomura analysts Rob Subbaraman and Toh Si Ying wrote in a research note that there are increasing signs that the world economy is entering a “synchronized growth slowdown, meaning countries can no longer rely on a rebound in exports for growth”.,Professor Manoj Pant, a prominent economist and vice chancellor at the Indian Institute of Foreign Trade, said that emerging markets would also be affected by a decline in trade; still, some factors may lessen the impact.,“The factors which are operating in our favor are that the bulk of the buying consumers are located in India, and the current geopolitical situation means a lot of countries are looking at India not as a complete replacement, but as a possible third area apart from China and Vietnam”, Pant told Sputnik.,Nomura forecasts a prolonged recession in the United States and a much deeper slump in Europe if Russia entirely cuts off gas to the region.,Despite the global headwinds, the Indian economy is predicted to grow at 7.2 percent in the current fiscal, much higher than any other major global economy.,Experts advise Indian policymakers to capitalize on the structural changes that began in 2016-17 onwards but that were interrupted by the COVID-19 pandemic.,“The world is moving much more towards services than manufacturing. China’s boom was based on manufacturing, the services boom will have to be in India. So the question is how well we are able to take account of that. So depending on us, we can actually gain substantially, if we are ready”, Pant added.,However, Pant labeled the new forecast as a continuation of the 2019 recessions, as there has been no boom registered anywhere in the world since then.,China infuses immense hopes to all the developing economies, as economists bet on demand from the world's second-largest economy to mitigate negative impacts, even though they face slowing export demand from the US and Europe.。
我们不难发现,这些年几乎所有手机APP安装包都在飞速变大、占用内存。这到底是为什么呢?本篇文章为探讨此问题,针对50款APP进行了分析。感兴趣的小伙伴们快来一起看看吧~前段时间,B站UP主科技老男孩在视频中提到,他发现2011年1月份发布的微信1.0版本,安卓APK安装包只有457KB,现在的微信安装包则是257MB,相当于11年膨胀了575倍。不止微信,在评论区,人们吐槽这些年几乎所有手机APP安装包都在飞速变大、占用内存。(B站UP主科技老男孩《逆向工程微信安装包,11年膨胀575倍到底更新了啥?》)为了更具体搞清楚这些年APP安装包的大小变化,我们在豌豆荚(一家提供安卓软件、安卓应用和安卓游戏下载资源的市场)查看了常用APP的历史版本数据。今年6月,Questmobile公布了2022年上半年用户规模过亿的58个手机APP,其中有50个APP可以在豌豆荚中找到历史版本数据。以下是针对这50款APP的分析。一、下载常用APP,光安装包就要占用7个G 2017年,极光数据发布了APP内存报告,统计显示,国内手机平均安装的APP数量已经达到50个以上。到了2020年第三季度,这一数据增加到56个。然而根据我们的统计,如今仅仅是把50款常用APP全部下载下来,光安装包的体积就达到了7180.51MB,也就是7.01G。但如果按照豌豆荚上能统计到的初始大小来算,这些APP的初始安装包只需要1143.46MB,也就1.14G。如果只看排名前20的APP,它们的安装包体积和从0.58GB变成了4.98GB,大概是原来的8倍。不仅如此,在安卓应用商城中,显示的安装包大小都是被压缩过的文件包大小,真正把APP下载到手机中,会有一个解压的过程。再加上许多APP在下载过程中会自动写入默认信息。这意味着,手机里需要预留比APP安装包体积更多的空间才能下载成功。通常情况下,一个APP占用空间是它安装包大小的1.5到3倍。

二 | 以微信为例,应用商城中显示微信安装包大小是230MB,但是解压之后变成了500多MB。按照占用空间=安装包大小*2.5来计算,大约需要17.6G才能放得下这50个常用APP,这还不包括使用APP带来的各种缓存,也不包括你需要用到的其他小众APP。二、8年间QQ安装包增长37倍,抖音极速版每年增长79% 50款常用手机APP中,谁占用空间最大?谁变化最大?我们首先从中找出安装包大小排名前五的APP,并统计了它们自上线以来历年安装包大小变化。安装包体积大的主要是游戏APP和社交APP。

三 | 如果从安装包体积的年平均增长率来看,排名则不同。抖音极速版安装包大小增速最快。

四 | 2019年9月2日极速版APP问世,上线三年后安装包大小就从13.13MB增长到75.11MB,平均每年增长79%。其次是农行掌上银行、QQ、UC浏览器和抖音。不同类型APP的增长不太一样。

五 | 游戏APP的安装包通常初始状态就不小,更新迭代也不慢。以手游代表王者荣耀为例,2015年上线时它的安装包是207.02MB,因为不断上线新英雄、新皮肤,增添新的玩法、模式,加上优化游戏体验等,7年后的现在,王者荣耀光是安装包就有2个G。社交APP的初始安装包比较小,但更新频繁,“每次变大一点点”,导致最后安装包体积也很大。

六 | 以8年安装包体积增长37倍的QQ为例,QQ的每次更新,主要变化在于功能的增加。

七 | 以2020年QQv8.4.18这一版本为例。对比过去,它的主要变化是:

八 | 这在一定程度上减少了下载另一个APP的麻烦,但问题是,虽然微信限制了小程序的大小(2MB),却没解决只要启动小程序就会产生的缓存。此外,对于那些割舍不了微信社交功能但不需要小程序、视频号等功能的人来说, 微信的“更新迭代”,都是手机空间的负累。如果你仔细观察也会发现,许多安装包飞速变大的APP,其实来源于头部互联网大厂,或者是由它们控股:腾讯旗下有微信、QQ、王者荣耀、QQ音乐……阿里巴巴有淘宝、支付宝、钉钉、UC浏览器……字节跳动有抖音、今日头条……这一方面是因为技术飞速发展,功能正常迭代;另一方面,APP不断更新和改版,越来越大、越来越全,很大一部分原因是对用户的抢夺和留存。于是你能看到,主打短视频的抖音、以种草出名的小红书,都出现了群聊功能;音乐软件QQ音乐,有“弹一弹”游戏;购物软件拼多多,本来底部有一个“推荐”的入口,今年年初变成了“多多视频”……或许正如网友说的那样:“有一天你的手机空间不够了,只能删除一些APP,但是第一时间要删除的肯定不是微信这样的刚需软件,就比如微信里面有个视频号,你说不定就会去把抖音卸载了。再比如你的美团里有买菜、买电影票、扫共享单车、打车的入口,又可以把盒马、滴滴之类的APP卸载……”*数据来源:豌豆荚、微信官网手动整理作者:张晨阳;编辑:唐也钦;公众号:DT财经原文链接:https://mp.weixin.qq.com/s/tZc-4KaOK0bNYjuvQMZFNw本文由 @DT财经 授权发布于人人都是产品经理。未经许可,禁止转载。题图来自 Unsplash,基于CC0协议。返回搜狐,查看更多责任编辑:
