农业农村部副部长 于康震：猪肉自给率的目标保持在95%左右。2018年，我国猪肉产量5403万吨，全球猪肉总出口量约800万吨，不到国内产量的15%。这几年我国猪肉进口总体保持增长势头，但最高年份进口的占比也就在2%左右。所以，解决中国老百姓的吃肉问题，必须坚持立足国内基本自给的方针。

（AlphaGo Zero which haslearned completely from scratch， from first principles withoutusing any human data and has achieved the highest level of performance overall。 The most important idea in AlphaGo Zero isthat it learns completely tabular rasa。 That meansit starts completely from a blank slate and figuresout for itself only from self-play， without any human knowledge， without anyhuman date， without any human examples or features or intervention from humans.It discovers how to play the game of Go completely from fist principles。 Sotabular rasa learning is extremely important to our goals and ambitions at DeepMind。 And the reason is that if you can achieve tabularasa leaning， you really have an agent that can be transplanted from the gameof Go to any other domain。 You untie yourself from the specifics of the domainyou’re in and you come up with an algorithm which is so general that it can beapplied anywhere。 For us the idea of AlphaGo is not to go out and defeathumans， but actually to discover what it means to do science， and for a programto be able to lean for itself what knowledge is。 So， what we start to see wasthat AlphaGo Zero not only rediscovered the common patterns and openings thathuman tend to play， these joseki patterns that human play in the corners。 Italso leaned them， discovered them and ultimately discarded them in preferencefor its own variants which humans don’t even know about or play at the moment。 And so wecan say that really what’s happened is that in a short space of time， AlphaGo Zero has understood all of the Go knowledgethat has been accumulated by humans over thousands of years of playing。 And it’s analyzedit and started to look at it and discover much of this knowledge for itself.And sometimes it’s chosen to actually to beyond that and come up with something which thehuman hadn’t even discovered in this time period。 And developed new pieces ofknowledge which were creative and novel in many ways。 ）

以零售业为例，此前辛格政府一直在推动外资引入议案，但各个邦的议会成员会互相博弈，担心外资零售业会对本地小零售商带来冲击。据环球网报道，2012年9月，印度开放多品牌零售业务准入，允许外资占企业投资比例最高达到51%。但当时，印度内部出现了强大的反对声音称，外资会侵蚀印度1200万传统零售商。当时，美国沃尔玛公司和英国特易购公司都对印度5000亿美元的零售市场表现出了浓厚的投资兴趣。但是，印度政府苛刻的投资政策和政策的变化无常让外资不得不暂时处于观望态度。

但可以看到，作为ST天宝实控人和董事长的黄作庆，在被捕之前，已经给公司留下了不少麻烦。首先是违规担保。黄作庆和承运投资在未履行审批决策程序及公司印章使用流程的情况下，与多个出借方签订借款和担保合同，导致ST天宝截至7月27日违规对外担保余额高达2.68亿元，占公司2018年度经审计净资产的10.36%。
