But while the population increased, the tillage failed to increase in the needed proportion. I have, unfortunately, no statistics for all periods; but the general tendency is shown by the following table:
Date Cultivated area mou per person in mou
1578 701,397,600 11.6
1662 531,135,800
1719 663,113,200
1729 878,176,000 6.1
(1953) (1,627,930,000) (2.7)
Six mou are about one acre. In 1578, there were 66 mou land per family of the total population. This was close to the figures regarded as ideal by Chinese early economists for the producing family (100 mou) considering the fact that about 80 per cent of all families at that time were producers. By 1729 it was only 35 mou per family, i.e. the land had to produce almost twice as much as before. We have shown that the agricultural developments in the Ming time greatly increased the productivity of the land. This then, obviously resulted in an increase of population. But by the middle of the eighteenth century, assuming that production doubled since the sixteenth century, population pressure was again as heavy as it had been then. And after c. 1750, population pressure continued to build up to the present time.
Internal colonization continued during the Manchu time; there was a continuous, but slow flow of people into Kwangsi, Kweichow, Yünnan. In spite of laws which prohibited emigration, Chinese also moved into South-East Asia. Chinese settlement in Manchuria was allowed only in the last years of the Manchus. But such internal colonization or emigration could alleviated the pressure only in some areas, while it continued to build up in others.
In Europe as well as in Japan, we find a strong population increase; in Europe at almost the same time as in China. But before population pressure became too serious in Europe or Japan, industry developed and absorbed the excess population. Thus, farms did not decrease too much in size. Too small farms are always and in many ways uneconomical. With the development of industries, the percentage of farm population decreased. In China, however, the farm population was still as high as 73.3 per cent of the total population in 1932 and the percentage rose to 81 per cent in 1950.
From the middle of the seventeenth century on, commercial activities, especially along the coast, continued to increase and we find gentry families who equip sons who were unwilling or not capable to study and to enter the ranks of the officials, but who were too unruly to sit in villages and collect the rent from the tenants of the family, with money to enter business. The newly settled areas of Kwangtung and Kwangsi were ideal places for them: here they could sell Chinese products to the native tribes or to the new settlers at high prices. Some of these men introduced new techniques from the old provinces of China into the "colonial" areas and set up dye factories, textile factories, etc., in the new towns of the south. But the greatest stimulus for these commercial activities was foreign, European trade. American silver which had flooded Europe in the sixteenth century, began to flow into China from the beginning of the seventeenth century on. The influx was stopped not until between 1661 and 1684 when the government again prohibited coastal shipping and removed coastal settlements into the interior in order to stop piracy along the coasts of Fukien and independence movements on Formosa. But even during these twenty-three years, the price of silver was so low that home production was given up because it did not pay off. In the eighteenth century, silver again continued to enter China, while silk and tea were exported. This demand led to a strong rise in the prices of silk and tea, and benefited the merchants. When, from the late eighteenth century on, opium began to be imported, the silver left China again. The merchants profited this time from the opium trade, but farmers had to suffer: the price of silver went up, and taxes had to be paid in silver, while farm products were sold for copper. By 1835, the ounce of silver had a value of 2,000 copper coins instead of one thousand before 1800. High gains in commerce prevented investment in industries, because they would give lower and later profits than commerce. From the nineteenth century on, more and more industrial goods were offered by importers which also prevented industrialization. Finally, the gentry basically remained anti-industrial and anti-business. They tried to operate necessary enterprises such as mining, melting, porcelain production as far as possible as government establishments; but as the operators were officials, they were not too business-minded and these enterprises did not develop well. The businessmen certainly had enough capital, but they invested it in land instead of investing it in industries which could at any moment be taken away by the government, controlled by the officials or forced to sell at set prices, and which were always subject to exploitation by dishonest officials. A businessman felt secure only when he had invested in land, when he had received an official title upon the payment of large sums of money, or when he succeeded to push at least one of his sons into the government bureaucracy. No doubt, in spite of all this, Chinese business and industry kept on developing in the Manchu time, but they did not develop at such a speed as to transform the country from an agrarian into a modern industrial nation.
3 Expansion in Central Asia; the first State treaty
The rise of the Manchu dynasty actually began under the K'ang-hsi rule (1663-1722). The emperor had three tasks. The first was the removal of the last supporters of the Ming dynasty and of the generals, such as Wu San-kui, who had tried to make themselves independent. This necessitated a long series of campaigns, most of them in the south-west or south of China; these scarcely affected the population of China proper. In 1683 Formosa was occupied and the last of the insurgent army commanders was defeated. It was shown above that the situation of all these leaders became hopeless as soon as the Manchus had occupied the rich Yangtze region and the intelligentsia and the gentry of that region had gone over to them.
A quite different type of insurgent commander was the Mongol prince Galdan. He, too, planned to make himself independent of Manchu overlordship. At first the Mongols had readily supported the Manchus, when the latter were making raids into China and there was plenty of booty. Now, however, the Manchus, under the influence of the Chinese gentry whom they brought, and could not but bring, to their court, were rapidly becoming Chinese in respect to culture. Even in the time of K'ang-hsi the Manchus began to forget Manchurian; they brought tutors to court to teach the young Manchus Chinese. Later even the emperors did not understand Manchurian! As a result of this process, the Mongols became alienated from the Manchurians, and the situation began once more to be the same as at the time of the Ming rulers. Thus Galdan tried to found an independent Mongol realm, free from Chinese influence.
