Heilongjiang Province in Northeast China has always grown a large portion of China's domestic soybeans and in the lead up to China's trade disputes with the U.S., the central government ordered the farmers there to plant less corn and even more soybeans so it could at least begin to fill the void of importing soybeans from the U.S.
How well does this kind of economy work especially for agriculture? It hasn't worked in the past, at least not for the farmers. My father in law here in the U.S. immigrated from China and he was a farmer back in China and as my experience with agriculture in China grows, it is more and more obvious that although there is some incentive for this current agriculture system to change, it is not changing simply due to the nature of the communist party of china and the political/governmental philosophies it has produced and cemented into the culture.
Without a true market economy, the agricultural system in China cannot significantly improve. Waiting on the central government for your every decision when it comes to planning does not work. Farmers need to be free to plan in advance for long periods of time in order to help manufacture more profits and based upon more stability. Until then, we can expect more of the same from China despite the dreams and desires of some of the people there for change, being locked out of the political system makes these dreams and desires a lost cause.
