沖縄、渡り鳥的生活からアジアの経済ハブへ
国勢調査データを元に沖縄の経済構造をネットワーク分析した。
沖縄、渡り鳥的生活からアジアの経済ハブへ (スライド資料）
沖縄は、1) 子育ての世界、2)学校中心の老人世界、3) ２つの世界をつなぐ移住性の渡り鳥的生活者の世界の３つに分かれる。
沖縄は転入と転出が多く、人的流動性の高い生活スタイルとなっている。
人的流動性を活かし、シンガポールのように人や物の流通のハブとなる政策が有効であるように思う。沖縄は新興国の中国と東南アジアの中心に位置し、アジア経済のハブとしての地理的条件も十分にある。アジアの経済ハブとして、空港、港湾等整備、税金の免除など政策が必要である。

Foreigners Activate Tokyo, but Lone Seniors Have a Problem
岩手県、外に出るか外で働くか
岩手県の経済活動を121の要因でネットワーク図を描いて、解析を行った。
岩手県の経済セクターは比較的はっきりと分離しており、お互いに関係性がないようだ。言葉は悪いが、岩手県の閉鎖的特徴が解析に現れたのではないか。人口流出が重要な課題となっており、商業の活性化が岩手県の活性化には重要となっている。また、中学生・高校生への配慮が必要である。
The economical sectors of Iwate prefecture is highly divided into 7 sectors as follows.
1. Child-caring familes working in service industry
2. Single people moving out from Iwate and commercial workers
3. Manufacturing workers
4. NEETs living with their mother
5. The old
6. Farmers and the old in a home
7. Male commuting workers including junior high school students
The analysis result clearly showed Iwate's feature of closeness.
Yamagata Needs Working Places. Medical Workers Cure the Lone Old.
Statistical survey discovered that Yamagata economy is divided into traditional and city life. Yamagata needs working places for commercial and manufacturing activity. Increasing the number of medical workers may cure the problem of the lone old in traditional life style.
山形県の経済は伝統的生活と都会的生活に分断されている。山形県には商業、製造業の事業所の増加が必要。独居老人問題もあるが、医療関係の労働人口を増やすことで解決可能。
We selected 121 factors from eStat data and made network analysis where factors connect each other with correlation coefficients.
We focused on 35 Yamagata cities from the Japan network analysis.
Traditional and City Life
We progressed network analysis of 121 factors on Yamagata cities. The factor network of Yamagata shows the factors are mainly divided into 2 separate regions in traditional (left) and city life (right).
The Old in Traditional Life
The left region indicates traditional life where majority is old people including school teachers, farmers, and manufacturing workers.
The City Life
The right region shows the city life since it has factors of nuclear family, crime rate, population density, and total taxpayer income price.
Top 10 of Betweeness
An statistical index of between indicates global hidden connectivity among all the network system. The following is top 10 of betweeness in Yamagata.
Factor Description Betweenness office working place 859.1 maker_employee employee in manufacturing 633.1 family_senior_single family of a single old 507.7 worker_medic.log worker in medical service 501.0 worker_2 worker in manufacturing 398.5 office_2 manufacturing working place 359.1 family_nucl_spouse nuclear family of husband & wife 342.9 family_trans family in 2005 317.5 merchant_office commercial office 304.0 worker_maker.log worker in manufacturing 289.5
More Working Place and Medical Workers for Yamagata
Yamagata has clearly separate structure of traditional and city life style. As shown in the betweenness list, manufacturing working places of high betweenness are critical factors connecting traditional life with city life as hubs. Increasing the manufacturing working place may activate economy in Yamagata.
There is a problem of the lone old in traditional world. Medical worker is also a critical factor in Yamagata. Increasing the number of medical worker will solve the lone old problem because it directly links to the lone old.
We recommend two policy of increasing working places and medical workers for the activation of Yamagata prefecture. We hope policy makers will utilize this network result to activate Yamagata's economy.
Okinawa, A Migratory Life Divided into Child-Caring Family and the Old

Three Regions in Okinawa
We progressed network analysis of 121 factors on Okinawa cities. The factor network of Okinawa shows that factors are mainly divided into 3 regions in left, middle, and right.
Child-Caring Families
The yellow green left region indicates the child-caring family composed of child and adult since the factors related to child and adult stand at the center of this region.
The Old Connected to School
The right region shows the old people. It has school-related factors in it. In Okinawa school system may be a center for the old.
Migratory Life of Okinawa
In the middle, there were migratory factors such as the people who move in, move out, work outside their own city, or orphans and the old in home. And divorced single persons tend to run restaurant for earning according to the network diagram.
Top 10 of Betweeness
An statistical index of between indicates hidden connectivity among all the network system. The following is top 10 of betweeness in Okinawa.
Factor Description Betweenness movein People moving in 186.6 employee_out Employees working outside the city 175.1 worker_gov.log Worker in government 169.0 moveout People moving out 161.1 family_faculty Orphans and the old in home 136.6 divorce Divorce Rate 120.5 maker_employee Employees in manufacturing 102.2 jhigh_student Junior high school students 100.4 popul_day_rate.log Population rate in day and night 97.4 maker_shipping.log Total product shipping price 86.7
As previously noted, the people moving in, moving out, and working outside the city has high betweenness score, showing these migratory factors connect the two divided world such as child-caring family and the old. As well known Okinawa has much high divorce rate among other prefectures in Japan, the result also indicates that divorce rate is a critical factors in Okinawa.
Okinawa Should Take a Migratory Policy
Okinawa was found to be a migratory life style by our analysis, having a feature where the people are coming in and out. Then we recommend Okinawa should take a migratory strategy to invite people and money by travel and tax-free policy, which Singapore succeeded as a center of East Asian hub airport. We hope policy makers in Okinawa will utilize this analysis result for the better economy situated among economically hot east asian countries.
Commerce and hotel business will activate Japan
Statistical survey discovered that commerce and hotel business will activate Japanese society.
統計分析によると、日本社会の活性化には宿泊・娯楽産業と商業の発展が重要である。
We selected 121 factors from eStat data and made network analysis where factors connect each other with correlation coefficients.
Metropolis and Countryside
The factor network of Japan shows that factors are mainly divided into 3 clusters in left, middle, and right. Factors of metropolis formed the left supercluster. Right region includes countryside supercluster, commerce, and manufacturing clusters. In the middle, there was hotel business and NEETs who don't work and live with their parent.
Importance of Global Connectivity
Network analysis have many feature index. Betweenness is an index which shows importance of global connectivity. Betweenness indicates a hidden important relay station on the networked system. We show a network diagram of factors where the betweenness was shown in the circle size.
Factor Description Betweenness merchant_employee commercial employee 164.0 restaurant restaurants 123.1 family_parent_m families with father 117.3 unemployed unemployed people 115.4 ground_residence.log ground price in residential area 113.2 high_student high school students 112.2 family_parent_f families with mother 108.8 garbage_emission garbage emission amount 107.4 garbage_recycle garbage recycling rate 102.0 elem_student elementary school children 94.7
Commerce is important
The factor of commercial employee (merchant_employee) has the highest betweenness score. As the network diagram shows, restaurants (restaurant) also has the high betweenness. Garbage emission amount (garbage_emission) is high because commercial activity causes a large amount of garbage as a consumption result. These three commercial factors situated on the middle side of the network system. They are regarded as relay station to the far metropolis and must be an important activating factors in the total system.
Travel Industry is welcomed
Hotel business (hotel) and amusement workers (employee_amuse.log) are situated between the metropolis and countryside superclusters. That means those two factors are activator of the system, which globally connect the two divided superclusters.
Commerce and Travel are activator
Our conclusion is that hotel business and commerce will activate the Japan society in the hidden layer of economical structure. We hope political decision will learn from this result and pursuit activation of Japanese economy.

Rich and Poor
We progressed network analysis of 121 factors on Tokyo cities. The factor network of Tokyo shows that factors are mainly divided into 3 regions in left, middle, and right. The yellow green left region indicates poor people since the factor of unemployed people stands at the center of this region. The right region shows the supercluster of rich people or high income taxpayers as tax income are situated near this region. In the middle, there were foreigners of large circle and workers.
Foreigner as a new working class in Tokyo
The following is top 10 of betweenness among 121 factors.
Label Description Betweenness foreigner.log foreigner 164.7 family_trans family in 2005 129.2 family_worker.log worker in family business 119.9 farmer_product.log agricultural product price 109.2 worker worker 106.1 family_senior_single single senior family 105.1 commuter_in commuter coming to this city 99.5 worker_3 tertiary industry worker 85.3 worker_miner.log mining worker 84.0 worker_3b tertiary industry worker 75.9
The factor of foreigner has the highest betweenness score. As the network diagram shows, foreigner is a hidden activator in Tokyo as workers. On the contrary to our expectation of Japanese homogeneity, foreigner may be a new working class in Tokyo cities, which connects the boundaries of rich and poor people in Tokyo.
Lone Senior Problem in Metropolis
When we look at the poor people region, single senior family is a remarkably large circle there. This suggests that the problem of lone seniors may drag other factor in the poverty in Tokyo.
Immigration Policy in Aging Society
We Japanese continued ethnic homogeneity long years. But in the coming age, we must confront multivalued society which accepts foreigners as living partner in all aspects for our future. Increasing foreign population may lead to some problems, but may also lead us to a rich cultural diversity. We expect policy in Tokyo will improve immigration environment.
And solution to the problem of lone seniors is also important since this problem is the critical point of poverty in metropolis.
