Because your state have to obey the policy and order of central government of India,the trade between the states not a international trade.in diploma and war you will be a single country.
You clearly have no understanding of what the differences have long been and continue to be between social programs, industrial and investment policies of Indian states and the legislative and executive powers reposed in the state (different to the federal govt) that have created differences in India's development.
Right from the start you clearly haven't even looked at Turkey's own investment data for the last 20 years in any relevant detail as to its composition and why it has been subpar. Which policies were lacking. Forget trying analysis.
You didn't even catch on my hint and look into what Turkiye's actual car exports are compared to say China either. Why hasn't Turkey simply expanded this to a larger amount? Just look at the data for yourself instead of coming to conclusions first thing.
Or just "blame China" because thats easier to do instead of your govt.
This conversation ends now from my side, there's no point.
No matter a Chinese province or California had almost similar gdp and population with Japan and Everyone will compare Japan to China or UK to US,not California to UK or Japan.
Comparisons within these countries are done on frequent basis as well to find where disparities in policy or other factors have resulted in different outcomes.
No large population country is homogeneous in development. China literally has something like 400 million or more internal migrant population that is extremely understudied socioeconomically given the hukou system (they work in different area to where they are registered and placed for govt support). That is without even looking at China's different regions and agricultural rural population either....or different layers of the CCP bureaucracy from local to central.
Once a country adopts federal structure as well (i.e states or sub-units can pass significantly different legislation to each other within bounds of the constitution), the scope increases even more....as there are significant policy drivers that separate their results over time.
Seperation of powers between federal and state govt is not some nominal thing with large countries like India, US.
İf use your idea Let s use only Istanbul,ok we are developed countriy
Not really, thats like picking a city in a sub-unit. Large states in India are immense populations with urban, rural and all sectors of economic activity covered.
I literally just told you my state is nearly the entire population of Turkey and you still don't understand.
There are states in India that have 100 million, 200 million or more people all with very different industrial policies and investment climate to each other (there is literal business ranking indices done for each state).
It is not some centralised homogeneous "everything is run in Delhi" thing to dismiss in some way.
Not my problem you don't understand any of this. Ciao.
