労働市場のネットワーク構造―都道府県データを用いた分析―
Network Structure of Japanese Labor Market -An Analysis Using Prefectural Datasets-
要旨Abstract
本稿では，都道府県レベルでの地域間労働移動の時系列的な動向を，移動指数に基づき，『労働市場年報』及び『雇用動向調査』を用いて分析した．その結果，『労働市場年報』ベースの指数が1990年代末以降は上昇傾向にある一方で，『雇用動向調査』ベースのそれは，ほぼ一貫して低下傾向にあることがわかった．両者の違いには，景気循環的要因のみならず，何らかの構造変化的な要因が影響していることが考えられる．また地方で，いずれのデータでも，地域間労働移動の時系列的な不活性化傾向が見られた．これは，日本の労働市場が地域的に分断化しつつあることの兆候である可能性がある．
In this paper I analyzed the time series trend of regional labor mobility based on a mobility index (the Shorrocks index) using two datasets compiled by Ministry of Health, Labor and Welfare, namely the Annual Report on Labor Market (ARLM) and the Survey on Employment Trends (SET). The former records labor mobility through public employment services (PES), while the latter is a national survey conducted on a broader scale. At the 47-prefectural level, it was found that the ARLM-based index has been gradually on the rise since the end of 1990's, while the SET-based index has been consistently on the decline throughout the sample period. There may be some structural factors specific to PES, as well as cyclical ones behind the difference them. On the other hand, at the 13-regional level, it was found that inter-regional mobility has become increasingly inactive throughout the sample period in both datasets. This fact may possibly indicate the advent of a regionally segmented labor market in Japan.
