What do we know about the punctuated equilibrium theory in China? A systematic review and research priorities

The punctuated equilibrium theory (PET) shows that government policy is mostly stable with occasional drastic change, which scholars attribute to institutional friction and limited information processing capacity. Although the existing PET literature predominantly focuses on democracies, scholars have started to apply the theory to authoritarian countries. Autocracies are a fertile testing ground for the theory's underlying mechanisms because they appear to experience less institutional friction but more informational restrictions than democracies. However, PET studies on autocracies are still rare. To deepen our understanding of the PET and the policy process beyond democracies, we conduct a systematic review of 88 Chinese language PET journal articles. We show that Chinese language PET research is increasing. Contrary to the English language PET literature, most Chinese studies are qualitative, while a key similarity is the weak operationalization of PET core concepts. The reviewed studies confirm a punctuated equilibrium pattern of policymaking in China but provide only limited evidence for more intense punctuations compared with democracies. Future PET research on China ought to use long-term data sets and examine institutional friction and information processing by policymakers. We also argue for more international exchange and comparative research to advance our understanding of the policy process in China and other autocracies.     

Provenance of Zhangzhou export blue-and-white and its clay source

Trace element compositions of 25 shards of Chinese Late Ming export blue-and-white porcelain from Zhangzhou and Jingdezhen kilns are analysed by Inductively Coupled Plasma Mass Spectrometry. Principle components analysis and REE distribution curves are used to establish method for provenance unknown Chinese export blue-and-white porcelain which may have originated from Zhangzhou or Jingdezhen kilns. By matching the REE distribution curves of Zhangzhou kiln samples and parent rocks of the possible clay sources used to make Zhangzhou blue-and-white, and comparing it with previous results of geological, geochemical and archaeological researches, the clay used for producing Zhangzhou export blue-and-white has been identified as having been collected from the weathered shells of a nearby potassium feldspar miarolitic granite outcrop.     

The Shuidonggou site complex: new excavations and implications for the earliest Late Paleolithic in North China

The initial Late Paleolithic, said to appear between 40 and 30 kya in eastern Asia, is defined by the appearance of many innovations. These archaeological indicators include the appearance of more refined stone tool making techniques (e.g., include the appearance of blade and microblade technology), complex hearth construction, use of pigments and personal ornamentation, as well as worked faunal implements such as bone and antler tools. We report here new findings from a multidisciplinary research project conducted at the Shuidonggou (Choei-tong-keou) site complex in northern China, a series of localities that date from the initial Late Paleolithic to the Neolithic.
