Not really. Such stock market crashes are an indication of some deeper problem in the economy, and China has too many of them. Don't look at these events in isolation, China already has an extraordinarily high debt to GDP ratio for a mid-income economy, their private debts are also high, and mostly invested in highly bloated real estates and excess infrastructure projects that are not making money, to tackle the situation the stock market bubble was created, so that the extra money from stock market can be used to ease out the debts in those sectors. Now with the stock market money is vanishing in thin air, the ripple effect will only prepone the bursting of bubble in the real estates and infrastructure sectors. We are looking at NPAs (bad debts) of unprecedented level in Chinese banking system, big enough to collapse their banking system and economy as a whole.
And that's not all, Chinese policy makers are also trying to 'inflate away' the bad debts, that means they are trying to reduce the value of money to ease the bad debts in net value terms. Apart from price rise, this move will also increase the cost of production in China and further drive away the manufacturing industry out of China leading to increased unemployment and making the debt crisis more critical, which is already a trend there.
Chinese policy makers are creating one monster after another to kill the previous monster, assuming that China is above the basic principals of economy, and the monster is becoming bigger and uncontrolable with each passing day.
And apart from a massive economic crisis, we are also looking at a social crisis here, they don't have the automatic pressure releasing valve of a functioning democracy!
