Statistical survey discovered that commerce and hotel business will activate Japanese society.
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.
