Basically a nation's GDP is the sum of a nation's consumption, private investment, government spending, and net export/import balance, generally given by the equation: Y= C + I + G + (X-M)
Y = GDP
C = consumption
I = investment
G = govt spending
X = export
M = import
So when we say China is transitioning from an investment led economy to a consumer led economy, it means that consumption will make up a greater proportion of gross domestic product compared to previous years when investment and govt spending may have made up a greater proportion of gross domestic product.
That's the perfect textbook definition, however, I think a few points needs to be expanded and clarified.
Firstly, I get the impression most media correspondents, and even many economic and financial experts seems more than a little muddled about what they mean by transitioning into a consumption driven economy, never mind how to go about achieving that. Probably because there are so few modern examples of this being successfully done.
In my view, there are broadly two key pre-requisites to transition from an export to consumption led economy. The first and most important is that domestic wealth and incomes need to be high enough to sustain it without having to resort to debt.
Every single day since the beginning of money, Chinese people have been spending money to consume. Obviously, the more wealthy the country and people, the more valuable that consumption is.
In effect, transitioning from an export to consumption based economy is a competition of spending power between your citizens and export destination countries' consumers.
So to sum up, in order to even consider transitioning to a consumption driven economy, all sorts of factors and indicators need to be considered. Things like wages, inflation, exchange rates, PPP indexes, debt levels.
Everything doesn't need to be at the same level, but taking the economy cumulatively, you need to be in the same ballpark.
The second condition is that the economy needs to be better geared towards persuading citizens to part with their hard earned money. That means more enticing and sophisticated products and services being made available.
In many ways, the second part of the equation is automatic. As citizens become more wealthy, more and more are able to afford previous luxuries only exported to richer foreign countries, and can even start to fund consumption imports of goodies from abroad in ever greater volume and value.
Transitioning to a consumption driven economy should be an automatic and gradual process. This is where even professional economists start to trip over themselves as they are, in effect, arguing for something that isn't 'natural' by market rules by effectively arguing for Chinese government intervention to speed up the transition.
Another reason even good economists make terrible suggestions is because their suggestions are not about what's best for the Chinese economy and people, but their own economies and peoples.
Most western calls for Chinese transition are either political or economically motivated.
Cheap Chinese exports are a popular political and popularist punching bag in the west to explain every ill under the sun afflicting western economies. Often with a heavy dose of unfair Chinese practices thrown in for good measure. It's far easier to blame those 'cheating' Chinese than to examine and own up to ones own mistakes.
The other side of the unseemly rush advocated by western commentators is that they are eyeing up the Chinese services market and desperately wants a piece of the massive pie the see.
This is actually pretty much the same thing as with western retailers and manufacturers when China was opening up and developing its manufacturing sector.
They want China to throw open the floodgates so they can rush in and grab market share Nd profits and get established before local competition can compete with them, and therefore preventing credible indiginous services industry from ever fully developing.
So when they are shouting for transition, what they are actually shouting for is access.
Personally, I don't think China is at the stage of transition yet.
While all the indices look promising, I think most analysist are not considering one aspect - debt. More specifically, consumption debt.
A massive port of western spending power is fuelled by household and government consumption debt, where money is borrowed to consume.
In effect, that brought future spending forwards, so western consumers were spending two or more years' income in one year. Of course the frugul and saving consicous Chinese consumer cannot compete with that, even if cumulatively, their disposible income is more.
In the short term, there is simply no way Chinese domestic consumption can be more valuable then western debt fuel consumption without China also getting on the same unsustanable train.
The 'new normal' in my view is less to do with Chinese transition (as that would involve the Chinese government trying to push the people into the terrible habit of consumption driven household and government debt) and more to do with adjusting expectations to what growth can be as western consumers and governments start to cut down on their own consumption debt habit.
Rather than look inward to try and get the people to borrow to spend, I think China's best strategy is what it is doing now - creating and opening up new markets in Africa, the Middle East and Central Asia.
That involves a lot of investment in those regions, which is exactly what China has been and is doing, to develop their economies to generate additional markets and export revenue.
But that takes time, hence the new normal.
