traditional economy as mostly successful with slow but steady growth in GDP per capita after the late 19th century. These scholars focus on the continuity of between features of the traditional economy and the PRC economy with its rapid growth. They believe that the PRC built upon the favourable conditions that existed during the Republican and late Qing periods, which allowed for the fast economic growth of the period. Civil war, famine and turmoil in the early republic The early republic was marked by frequent wars and factional struggles. Following the presidency of Yuan Shikai to 1927, famine, war and change of government was the norm in Chinese politics, with provinces periodically declaring "independence". The collapse of central authority caused the economic contraction that was in place during final Qing decades to speed up, and was only reversed after China reunified in 1927 under the rule of Nationalist Generalissimo Chiang Kai-shek. Development of domesticated industries Chinese domestic industries developed rapidly after the downfall of the Qing dynasty, despite turmoil in Chinese politics. Development of these industries peaked during World War I, which saw a great increase in demand for Chinese goods, which benefitted China's industries. In addition, imports to China grew drastically after total war broke out in Europe. For example, China's textile industry had 482,192 needle machines in 1913, while by 1918 (the end of the war) that number had gone up to 647,570. The number increased even faster to 1,248,282 by 1921. In addition, bread factories went up from 57 to 131. The May 4th movement, in which Chinese students called on China's population to reject purchasing products not made in China, in other words, boycotting foreign goods, also helped spur development. Foreign imports fell drastically from 1919 to 1921 and from 1925 to 1927. Despite the outbreak of the Great Depression in 1929, Chinese industry continued to grow and develop into the 1930s. This era is now known as the Nanking decade, a time period seen as commencing when the KMT under Chiang Kai-shek re-unified most of China, bringing a level of political stability not seen in decades. Under Chiang Kai-shek's Nanking based government, China's economy enjoyed unprecedented growth from 1927 to 1931. By 1931 however, the effects of the Great Depression began to badly impact the Chinese economy, a problem compounded further by Japan's invasion and occupation of Manchuria in the same year. Consequently, China's overall
