In recent years, with the economic development and the improvement of living standards in China, the energy consumption has been increasing significantly. To create a sustainable society, it is important to clarify the energy consumption and CO₂ emissions in the residential sector, especially that in the urban houses because China is in the process of urbanization.
 Studies on the residential energy consumption in China have been carried out in Japan as well as China. Yoshino et al.¹⁾ have made clear the energy consumption of apartment houses for six Chinese cities by surveying; Zhang et al.²⁾ clarified the energy consumption for the capital cities in China in 1997 using the official statistics, developing a model predicting energy consumption in the residential houses in China; Ning et al.³⁾ investigated the structure of energy consumption using the Chinese statistics; Yu et al.⁴⁾ clarified energy consumption by questionnaire surveying and simulations for six Chinese cities; Ling et al.⁵⁾ investigated the consumption of electricity and gas for 23 areas in Beijing and made clear the average energy consumption except energy for district heating. All these studies can be classified into two methods: statistical and survey methods. With the statistical method, researches often face the problem of lacking the items needed in their researches; but with the survey method, it is difficult to tell if the results can represent the reality. Because the statistical method is based on large number of residents, it is used in this study. All the studies mentioned above have not been able to make clear the trend of energy consumption in the urban houses, nor the CO₂ emissions caused by the energy consumption.
 In this study, based on Chinese statistics, unit energy consumption for 277 Chinese cities is clarified during the period of 2002-2012. The emissions of CO₂ caused by energy consumption per household are also analyzed. The main conclusions of this study are as follows:
 (1) Energy consumption per urban household increases from 12.3 GJ to 23.1GJ in the period of 2002 - 2012. The percentage of each kind of energy was clarified;
 (2) The emissions of CO₂ per urban household increases from 1, 689 kg CO₂ to 3,559 kg CO₂ in the period of 2002 - 2012. The weight of CO₂ emissions caused by different kinds of energy resources was made clear;
 (3) Energy consumption and CO₂ emissions per household in the capital cities is 1.44-fold and 1.42-fold of the average, respectively.

This study is an evaluation of the old towers in Shanxi, China. We use the method of Quantification Theory I and III. The study deals with 30 old towers as a sample, and aims to work out a model by which an appropriate evaluation of tourist resources can be obtained. 3 key factors are taken in evaluating the old towers, namely times, height and buildings artistry. This method is also applicable to any other tourist resources such as monastery, grottos, mountains, etc, in China.

本研究は、中国の 212都市を対象として、土地使用権の流動性と都市特性との関連性を明らかにした上で、地域の状況に応じた今後の土地利用管理政策についての方向性を提示することを目的としたものである。先ず、 1949年から現在までの中国の土地利用制度と土地管理政策を整理し、五つの時期に分け、各時期の特徴を明らかにする。次に、対象都市の都市経済指標と土地利用指標を用いて、主成分分析 /クラスター分析を行い、 7グループに類型し、各グループの経済発展レベルと都市化レベルの対応関係及び特徴を明らかにする。最後に、類型ごとの都市特性と土地使用権の転換状況の関係を比較分析・考察し、その結果に基づいて、類型ごとの今後の土地利用管理政策の方向性を提示している。
