这个主持人从头到尾在有意无意把张维迎往她想带的方向去带，并不像是一位采访者，倒像是质疑者。当然，问题不大，因为张维迎足够有学识，轻松逐一化解。如果比作博弈，主动出击的女主持人最终输得体无完肤……

阿里集团的股价当天在香港证券交易所下跌了近4%。阿里巴巴在纽交所的股价也在这一年来从每股超过300美元的高点，下跌至每股170美元左右。
阿里巴巴集团董事会主席兼首席执行官张勇(Daniel Zhang)在9月3日的声明中表示，阿里 "迫不及待地要为实现共同富裕做出贡献" ，“我们坚信：国家好，社会好，阿里巴巴才会好。我们愿为在高质量发展中实现共同富裕贡献绵薄之力。”
据彭博社统计，八月以来，至少73家中国上市公司在业绩财报中提及响应“共富”政策。而继科技巨头腾讯先后宣布投入1000亿人民币用于“可持续社会价值创新”项目及“共同富裕专项计划”之后，9月2日，阿里巴巴也宣布投入1000亿人民币启动“助力共同富裕十大行动”。
张维迎: 离开市场经济将“共同贫穷”
“共富风”在中国吹起之际，北京大学经济学教授张维迎9月1日在中国经济50人论坛上发表一篇题为《市场经济与共同富裕》的万字文章。他提出警告，若中国失去对市场经济的信念，引入越来越多的政府干预，恐将走向“共同贫穷”
“其实三句就够了。第一句，共同富裕是假的。第二句，共同富裕就是政府逼民企掏钱，用这个口号掩盖对民企逼捐的做法，同时把民众舆论引导到对民企的不满与妒忌。第三句，共产党要‘共产’是早晚的事。”程晓农说。
张维迎对计划经济提出尖锐的批评，“计划经济是少数知识分子设计、然后靠强权从上到下强加给社会的，所以一定有人捍卫它，替它辩护。市场经济不同，它不是知识分子设计出来的，而是从下到上自发产生的。”他写道，“从历史上可以看到，反对市场经济的最大力量，就是特权阶层和既得利益者。”
程晓农 | 共同富裕 | 中国最有钱的人在哪里？
共同富裕里面有个东西要讲穿，谁和谁一起富裕？要追问一下，中国最有钱的人在哪里？在高官、各级官员、中小干部中，他们打算共同富裕吗？那就应该从各级常委的资产开始嘛。”

I like to work on this research carefully, since I invested near 20000 shares of GTE stock around 89 Canadian cents. I like to learn how to analyze a company, and I like to choose a company simple enough like commodity business, I can understand how to measure my risk, and understand financial issues like debts.
0.43/ share on June 2020 | Price indicating for bankrupt | How to calculate the price based on reserves
I went through the article again, and I like to use this article as an example to study again and again.

Here is the article.
The latest oil price collapse has hit Canadian oil stocks particularly hard. A sharp demand shock triggered by the coronavirus pandemic is weighing heavily on energy prices.
Among the worst affected is Colombian-based driller Gran Tierra (TSX:GTE)(NYSE:GTE). Its stock has plunged by a massive 89% since the start of 2020. This is significantly higher than Brent’s 63% loss, which sees it trading at around US$22 per barrel.
Gran Tierra is trading at almost a ninth of its 52-week high. That coupled with the latest sell-off indicate the market is pricing the intermediate oil producer for bankruptcy. For some time, I have been bullish on Gran Tierra, because it has been trading at a deep discount to the net asset value of its proven and probable oil reserves.
Let’s take a closer look at what the future potentially holds for the beaten-down driller.
In response to the coronavirus pandemic and oil price collapse Gran Tierra slashed its 2020 capital spending by over 60%. That sees the driller expecting to spend a maximum of US$80 million on drilling and well-development activities.
Gran Tierra is also suspending uneconomic production to reduce expenses. By mid-April 2020, Gran Tierra had shuttered around 11,300 barrels daily of oil production. This includes 4,000 barrels from Gran Tierra’s Suroriente and PUT-7 Blocks in the Putumayo basin, where operations ceased because of a local farmer blockade.
That reduction in oil output, while reducing costs, will magnify the impact of sharply weaker oil prices on Gran Tierra’s earnings.
A key headwind being faced by Gran Tierra in the current harsh operating environment is its weak financial position. The driller finished 2019 with a paltry US$8 million in cash compared to over US$803 million of long-term liabilities, including US$700 million of long-term debt. Gran Tierra’s long-term debt was a conservative 1.9 times its 2019 EBITDA, indicating that prior to the oil price collapses it was very manageable.
The most pressing issue for Gran Tierra is its lack of cash in what is shaping up to be an especially harsh operating environment that no one predicted.
Other than its revolving credit facility, Gran Tierra has no near-term debt maturities. Its convertible notes totaling US$600 million don’t mature until 2025 when US$300 million falls due, with a further US$300 million in 2027. Gran Tierra also has a US$300 million credit facility, which matures during November 2022. Currently, there is US$118 million drawn on the facility and US$182 million available, boosting Gran Tierra’s liquidity.
Despite the lack of cash on hand, Gran Tierra’s overall financial position appears sound.
Nonetheless, at $0.39 per share, the market is pricing Gran Tierra for bankruptcy. That price is a mere 15th of the after-tax net asset value of Gran Tierra’s proven and probable oil reserves.
Gran Tierra is in a superior position compared to its peers operating solely in North America. It can access international Brent oil prices, giving it a handy financial advantage. This is because Brent trades at a US$5-per-barrel premium to the North American West Texas Intermediate (WTI) benchmark.
This — along with low operating and transportation expenses, which for 2020 were originally estimated to be US$10.50 per barrel pumped — means Gran Tierra’s operations should be cash flow positive in the current difficult operating environment.
Gran Tierra appears extremely attractively valued, despite the oil price collapse. Even Gran Tierra’s low liquidity is not a serious issue when its well-laddered debt profile and manageable level debt are considered.
Other than rising geopolitical risk in Colombia and operational outages caused by farmer blockades, there is no reasonable explanation as to why Gran Tierra has been heavily marked down by the market. For these reasons, Gran Tierra should emerge from the coronavirus-induced oil price collapse as a going concern.
Neveretheless, despite Gran Tierra’s appealing valuation, it should be treated as speculative, high-risk, contrarian play on higher oil.
