First, Ukraine's economic system is a capitalist free economy. Ukraine has both an area and a lot of energy. However, the main reason why its economy has been unable to develop is that since the disintegration of the Soviet Union, the economic system of Ukraine as a whole has changed from the original planned economy to the present capitalist free economy. However, it turns out that the capitalist free economy that Ukraine is now implementing is not suitable for this country. Because Ukraine's free economy is not suitable for its own development, it will always be hindered by many forces in the process of economic development.
Second, Ukraine's military strength is not strong enough. The reason why the Ukrainian economy has not developed is not only related to its own economic system, but also a particularly important reason is that Ukraine's military strength is not strong enough. Because Ukraine's military strength is not strong enough, and its entire country is particularly rich in energy, neighboring countries are trying to provoke Ukraine. In the end, it directly led to the fact that Ukraine was often in a state of dynamic gear. However, as we all know, a turbulent country's economy will certainly be affected and it is impossible to develop steadily. Many times, Ukraine is always in an unstable and particularly turbulent state. In addition, the war between Ukraine and Russia caused a serious setback to the Ukrainian economy.
To sum up, I personally think that the reason why Ukraine's economy has been unable to develop is mainly because Ukraine's economic system is a capitalist free economy and its military strength is not strong enough.
