Restoration of micro data of John Lossing Buck's survey and analysis of the inverse relationship between yield and farm size in rural China in the 1930's

A large scale Chinese agricultural survey was conducted at the direction of John Lossing Buck from 1929 through 1933. At the end of the 1990’s, some parts of the original micro data of Buck’s survey were discovered at Nanjing Agricultural University. An international joint study was begun to restore micro data of Buck’s survey and construct parts of the micro database on both the crop yield survey and special expenditure survey. This paper includes a summary of the characteristics of farmlands and cropping patterns in crop yield micro data that covered 2,102 farmers in 20 counties of 9 provinces. In order to test the classical hypothesis of whether or not an inverse relationship between land productivity and cultivated area may be observed in developing countries, a Box-Cox transformation test was conducted for functional forms on five main crops of Buck’s crop yield survey. The result of the test shows that the relationship between land productivity and cultivated areas of wheat and barley is linear and somewhat negative; those of rice, rapeseed, and seed cotton appear to be slightly positive. It can be tentatively concluded that the relationship between cultivated area and land productivity are not the same among crops, and the difference of labor intensity and the level of commercialization of each crop may be strongly related to the existence or non-existence of inverse relationships.

Dynamics of investment negotiations between China and Japan : the China-Japan-Korea trilateral investment treaty and beyond

The investment agreement relationship between China and Japan is complex. The many intersecting and overlapping agreements can rightly be described as a "noodle bowl of agreements." The 1989 bilateral investment treaty (BIT) between China and Japan still stands. Japan can also free-ride on the negotiation outcome of China's BITs and free trade agreements (FTAs) with other countries by using the most-favored-nation (MFN) provision in the 1989 China-Japan BIT, which does not contain regional economic integration organization (REIO) exception rules. However, because the China-Japan BIT does not have investor-state dispute settlement (ISDS), it may face implementation problems. The China-Japan-Korea trilateral investment treaty (CJK TIT), in force since 2014, made improvements upon the 1989 BIT, but Japan is not entirely satisfied with the outcome. For Japan, pre-establishment national treatment (NT) and prohibition of various types of performance requirements are the most important negotiation items, but the CJK TIT insufficiently addressed those problems. Moreover, because the CJK TIT has MFN provisions with an REIO exception rule, better access to investment markets brought about by future FTAs such as the China-Korea FTA and the EU-China FTA cannot be imported into CJK TIT. Hence, in the long run, Japan needs to pursue an FTA investment chapter with China that covers both MFN and ISDS.
