Sagot :

To determine the country which showed the greatest percentage increase in world manufacturing from 1870 to 1913, we need to calculate the difference in the percentage of world manufacturing for each country over this period. The data provided is as follows:

| Country | 1870 (%) | 1913 (%) |
|-----------------|-----------|----------|
| US | 23 | 36 |
| Germany | 13 | 16 |
| Great Britain | 32 | 14 |
| France | 10 | 6 |
| Russia | 4 | 6 |
| Belgium | 3 | 2 |

### Step-by-Step Calculation:

1. US:
- 1913: 36%
- 1870: 23%
- Increase: 36% - 23% = 13%

2. Germany:
- 1913: 16%
- 1870: 13%
- Increase: 16% - 13% = 3%

3. Great Britain:
- 1913: 14%
- 1870: 32%
- Decrease: 14% - 32% = -18% (is a decrease)

4. France:
- 1913: 6%
- 1870: 10%
- Decrease: 6% - 10% = -4% (is a decrease)

5. Russia:
- 1913: 6%
- 1870: 4%
- Increase: 6% - 4% = 2%

6. Belgium:
- 1913: 2%
- 1870: 3%
- Decrease: 2% - 3% = -1% (is a decrease)

### Summary of Percentage Changes:
- US: 13% increase
- Germany: 3% increase
- Great Britain: -18% (decrease)
- France: -4% (decrease)
- Russia: 2% increase
- Belgium: -1% (decrease)

From these calculations, we can see that the United States had the greatest percentage increase in world manufacturing, which is 13%.

Therefore, the country that showed the greatest percentage increase in world manufacturing from 1870 to 1913 is the United States.
