If we do not set GDP, GDP growth, and the cost of weapons, there will be no way to talk about war, after all, resources determine strategy, and strategy affects tactics.

*

1. Total GDP

In 1911, the national GDP was set at $6.5 billion.

Because of memory errors, the GDP in 1911 was set slightly higher (actually around 5 billion US dollars, see "Late Qing Fiscal and Economic Research", p255), but considering the scale of Tianzihao and the economic growth rate of up to 7% in 1911-1929, 18 years (the smaller the economic aggregate, the faster the economic growth, the "Late Qing Fiscal and Economic Research" believes that from 1887 to 1920, the average annual growth rate of the national economy was 3.55%, including revolutions, several wars and famines), In the long run, the initial error of the setting is slightly acceptable, and it cannot be changed, so it has to be settled.

2. GDP growth

1911-1921, driven by the war, the growth rate was 7%; Japan Unknown; GDP in 1921, medium, $13 billion; day, $6.665 billion

From 1922 to 1928, due to the dividends of World War I, the growth rate was 7%, and that of Japan was 4%; GDP in 1928: US$28.075 billion, US$8.75 billion, and US$800 million.

1929-, taking into account the fact that the damage was not heavy and the pre-war pull, the average value is tentatively estimated to be 3.8%; At the same time, the economic integration of China, Japan and South Korea, the GDP growth rate is synchronized,

3. The cost of weapons

*

Weapons and ships are related to many factors such as resources, manpower, technology, and weapon structure of each country. But given the similarities between China and Japan (except for coastal cities such as Shanghai, Chinese labor is actually cheaper than Japan. This can be seen from the per capita GDP of China and Japan), which can only be exhibited with Nissan weapons. The United States should not be used as a reference.

Note: The price index is a splicing of several data, but because it is only an index and is connected from year to year, although the index is different, it can be proportional. Because it was a World War II weapon, it was set at the origin of 1936, and its price index was 1, and the exchange rate of 1 yen against the US dollar in that year was 0.29, (1 US dollar = 2 Chinese yuan). The conversion of Japanese Yen to Chinese Dollar is as follows:

*

Example 1: The cost of the aircraft carrier Shozuru is 88,490,006,983 yen. How much is the cost of converting Huayuan?

Check: The ship is an aircraft carrier planned for the Maruzan project, and the cost was compiled in 1937, with an estimated cost of 80.85 million yuan and an actual cost of 88,496,983 yen

Therefore: 8849.6983/price index 1.26 = 70,235,700 yen, converted to Chinese dollars: 70,235,700 x 0.29 x 2 = 4073.6706 Chinese dollars

*

Example 2: The cost of the Soryu aircraft carrier is 40.2 million yen, what is the cost of converting to Chinese dollars?

Cha: The ship is an aircraft carrier planned to be built by Maruji, the cost was compiled in 1934, and it is estimated that 40.2 million ships will be built, but the actual situation is unknown.

Therefore: 40.2 million / price index 0.899 = 44.7163 million yuan. Converted to Chinese dollars, 44,716,300 x 0.29 x2 = 25,935,400 Chinese dollars

*

Example 3: The cost of the Yunlong aircraft carrier is 93.442 million yen, how much does it cost to convert to Huayuan?

Cha: The ship was built as an aircraft carrier under the Five-Year Plan, and the cost was compiled in 1942. It is estimated that the actual cost of the ship is 93.442 million yen.

Therefore: 93.442 million / price index 1.91 = 4892.36 yen, which is converted to 28.375 million Chinese dollars

4. Cost adjustment

Affected by this, the cost of weapons and ships will be adjusted for appropriate reasons in the future, and additional labor and efficiency bonuses will be added. (To be continued.) )
