JaLCDOI 10.18926/OER/40609 An Econometric Study on the Urban Population Density Functions : A Survey Nakamura, Ryohei| Li, Jie| Since the seminal work by Clark (1951), a number of researches on urban population density have been appeared in several journals. In 1989 McDonald conducted a survey on the econometric study of urban population density functions. In the review he recommended the estimation technique pointed by Frankena (1978) and the use of Box−Cox transformation for choosing an optimal functional form. He also addressed to the model and estimation of beyond the distance−density functions such as varying parameter model. This paper begins in the second section with a choice of functional form. Sections 3 and 4 review the estimation model of suburbanization and the identification of the CBD including multi−center case. Recently more complicated population distributions are found in the real urban areas. Thus, more sophisticated models are needed to explain the real population distribution. In section 5 three estimation models ; cubic−spline, switching regression, and varying coefficient models are reviewed and in the varying coefficient model we propose theoretical foundations for the estimation of varying parameter model. In section 6 we describe data problems concerning population density estimation and estimation bias when we use census tract data. Finally, section 7 states a possible direction of the further research. 岡山大学経済学会雑誌 2001-06-10 volume33 issue1 15 34 0386-3069 日本語 publisher

JaLCDOI 10.18926/OER/60003 Construction of IO Table in cities, towns, and villages: New Approach 中村 良平| This paper proposes a new approach to construct IO Table called“ Reduced Form Approach.” There are a survey method and a non-survey method for constructing the regional input-output table. This paper proposes a hybrid approach that combines a survey method in terms of utilizing individual information and a survey method in the sense of conducting a questionnaire survey of business establishments. 　The most difficult part of constructing a regional input-output table is estimating the value of exports and imports. Furthermore, in an open regional economy, exports and imports have a large weight. In many of the conventional methods, the import/export rate was taken from the input-output table of the prefecture, and the import/export value was extracted as the residual of the expenditure balance. In this paper, we propose a “Reduced Form Approach” that reproduces the input-output table from the production induced value. This not only overcomes the difficulty of balance adjustment, but also realizes the visibility of simulation analysis using an input-output table.

JaLCDOI 10.18926/OER/41575 'City Position of Importance in the Age of Honsyu-Shikoku Three Big Bridges : II Nakamura, Ryohei| More than ten year ago Seto-Ohashi was constructed, last April Akashi-Kaikyo-Ohashi was completed, and this May Onomichi-Imabari route is going to be provided as the third road connecting Honsyu with Shikoku area. At the end of this century, as a result, Seto-uchi area has three main routes which would improve interregional mobility. Progress of traffic infrastructure could change city's economic position. On one side, some cities may growth by improving interregional accessibility. On the other side, however, some cities may lose their economic status due to so called 'straw effects'. This paper consists of two parts; the former part is focussed on recent regional economic changes and statistical analyses on city position of importance, the latter part is empirical investigation based on the results of questionnaire about city positions of importance. Regional recent changes mean office location and relocation as a firms' regional evaluations. In statistical analyses I propose a new indicator ofcity's relative economic importance. Questionnaire has been conducted for branch offices of major four cities in Seto-uchi area. Through questionnaire several evaluations of individual cities by corporate firms are clarified. 岡山大学経済学会雑誌 1999-03-10 volume30 issue4 333 388 0386-3069 日本語 publisher

JaLCDOI 10.18926/OER/47075 Before and After the Merger of Municipalities: The Case of Okayama Prefecture Nakamura, Ryohei| Watanabe, Takashi| This study concerns about before and after the merger of municipalities focusing on the case of Okayama Prefecture. By conducting questionnaire survey on municipalities, we examine the change of public service, tax burden, and resident consciousness. By expanding municipal areas it is becoming difficult to pick up needs of residents while some efficiency is attained by scale effects. Thus in order to overcome financial deficit and maintain public services it is quite important for all local municipalities to find out new basic industry for obtaining export money. 岡山大学経済学会雑誌 2011-09-26 volume43 issue2 1 27 0386-3069 日本語 Copyright © 2011 岡山大学経済学会 publisher
JaLCDOI 10.18926/OER/41471 Kibi Plateau City: Planning Process and Evaluation by Questionnaire to Residents Nakamura, Ryohei| 'Kibi Plateau City' had been planned in 1974 and its construction started in 1981. Construction plan is divided into two intervals. The former interval of the construction plan was completed in 1993. The latter interval, however, has been freezing due to the local financial crisis of Okayama Prefecture. This paper first reviews planning process of 'Kibi Plateau City' and picks up current problems by statistical data and articles of newspapers. Secondly, questionnaire is made up and implemented to residents. Finally, according to the results of the questionnaire an evaluation of 'Kibi Plateau City' is proposed. 岡山大学経済学会雑誌 2000-11-20 volume32 issue3 1 51 0386-3069 日本語 publisher

JaLCDOI 10.18926/OER/40537 Regional Economic Interdependency in an Open Economy : An Introduction Nakamura, Ryohei| In this article I present an estimation procedure for regional economic variables which determine regional economic independency or autonomy such as export and import using some statistical data. In recent years not a few regions have been experienced a dependency on Tokyo central region in many respects and also been noticed thin effects of past policies in order to vitalize regional economies. The most important point is that local government does not recognize spillover effect which is derived from implementing regional policies. For examples, some materials are imported from outside the region even if local government invests on public capital formation, or some amounts of output sales are often transferred to headquarters at Tokyo from local factories. The local government, Akasaka−cho in Okayama Prefecture, has noticed the above situation and made a research project evaluating regional spillover/spillin effect in monetary term, which means to construct small region’s IO table in an extended version. As a result, Akasaka−cho grasped the circular−flow−of−the−economy constitution of the area, and carried out the policy evaluation analysis using it and succeeded to introduce regional money circular type factory and also job−creating industry. However, the case like Akasaka−cho is a very unique. To conduct such a research it is necessary for local governments to prepare both much time and money. Thus, this paper showed the model which estimates one section of a regional economy circulation constitution from such enquiry and the existing statistical data, and the example of an actual proof in the Tsuyama City zone is shown. By doing this procedure, we can identify which industry is baasic or nonbasic or which industry is effective for spreading an economic consequence. I want to develop the estimation procedure of an expenditure side from now on, to combine with a questionnaire or hearing enquiry, and to build the means of grasping the circulation constitution of regional economy comprehensively. 岡山大学経済学会雑誌 2005-03-10 volume36 issue4 39 67 0386-3069 http://www.e.okayama-u.ac.jp/gakkai/ 日本語 publisher
JaLCDOI 10.18926/OER/49028 Regional Industrial Agglomeration and Home Market Effects: The comparison among three different specifications Watanabe, Atsushi| Nakamura, Ryohei| The region with a large market tends to increase the number of firms. We can often see the phenomenon of expanding economic disparities between regions. Krugman described this phenomenon using theoretical model and also he defined the concept of home market effect. The home market effect means that the production activity is done over the ratio of market (demand volume) in the region itself. However, by changing the assumption such as Davis (1998), the home market effect does not exist in the theoretical model. Although various empirical studies have been tested, the home market effect has not been necessarily confirmed. In this paper, we analyze the home market effect using the three specifications. Two specifications out of the three specifications are derived from the new economic geography, the rest specification out of the three specifications is derived from international trade. In doing so, it is possible to test the home market effect from various angles, and consider the validity of home market effect. Looking at the overall empirical results, the home market effect is confirmed in a number of manufacturing industries. Also, the home market effect is always confirmed in the six heavy and chemical industries such as chemical industry. 岡山大学経済学会雑誌 2012-12-10 volume44 issue3 1 22 0386-3069 日本語 Copyright © 2012 岡山大学経済学会 publisher

JaLCDOI 10.18926/OER/41498 An Evaluation for Tenant Benefits in Public Housing: A Case of Okayama City Nakamura, Ryohei| Morita, Manabu| In this paper we estimate the tenant benefits in public rental housing supplied by local government on the basis of the data for private housing as well as public housing. In the estimation we specify a Cobb-Douglas utility function defined by housing attributes and other goods, and present a new estimation form of Hicks equivalent variation taking into account implicit marginal prices of public housing. Our work recognizes that the unit cost of housing is different between private and public housings, which is not identified by previous studies. The proposed procedure in this paper requires the estimation of implicit marginal prices of public housing attributes and private housing attributes. We further analyze the relationship between benefits of public housing and subsidy for rent, defined as the difference between the market value of public housing and rent of public housing, and examine the distribution ofthe benefits by household characteristics. This study finds that the calculated benefits from the public housing were 10.0 percent of monthly income, and evidence that benefits are related to income. Our results provide the effectiveness of public rental housing for the lower income households. 岡山大学経済学会雑誌 1999-12-10 volume31 issue3 35 64 0386-3069 日本語 publisher

JaLCDOI 10.18926/OER/47076 Xuan, Chao| Nakamura, Ryohei| This paper treats the empirical issue related to the urban productive efficiency. First, we construct a model incorporating urban inefficiency term and estimate a stochastic frontier production function at urban level. Next, we compare technical efficiency across Chinese cities during 1997-2007 by using estimated results. The urban technical inefficiency effect is found to be significant in many cities. Then, in the way of constructing the specification of the technical inefficiency in terms of various capital explanatory variables, we analyze the determinants of technical inefficiency of individual cities, and explore how the urban technical inefficiency is influenced by capital density, FDI, the domestic investment, while the impact of technical inefficiency on capital variables is investigated. From the empirical results, FDI is able to reduce effectively the technical inefficiency. Capital intensive industry would be the engine of economic growth in the future. technical inefficiency urban productivity stochastic frontier approach chinese cities 岡山大学経済学会雑誌 2011-09-26 volume43 issue2 29 44 0386-3069 http://www.e.okayama-u.ac.jp/gakkai/ 英語 Copyright © 2011 岡山大学経済学会 publisher
