| Title Alternative | Analysis of Regional Multiplier of Knowledge Intensive Industries and Creative Jobs based on Economic Base Model: Benefit of Municipal Collaboration |
| FullText URL | oer_055_3_001_024.pdf |
| Author | Nakamura, Ryohei| |
| Abstract | The traditional economic base model in the field of regional science contributes to identifying regional income producing industries and labor absorption. The economic base model has some conditional assumptions while it is quite tractable. Recently, papers by Moretti and others show significant regional multiplier effects of innovative jobs. They refocused on the traditional economic base model. However, their approach has several deficiencies concerning the identification of basic/non-basic industries and ambiguity of multiplier generating mechanisms. This paper focuses on regional specialization of knowledge intensive industries and creative jobs which are the driving forces of regional development in the framework of the economic base model. The estimations of regional economic multiplier in terms of employment are carried out using two-digit employment and three-digit job classification data at local municipality level with two-period data. Using these data, I explain regional differences by degree of specialization of knowledge intensive industries and creative workers. By doing this, I propose contemporary regional economic policy. Furthermore, by comparing multiplier effects at local municipality level and regional employment area level, benefits of municipal consolidation are shown. |

| Abstract | The purpose of this study is to verify the fault length and earthquake magnitude of the Iyo-Bungo earthquake in 1596 estimated by Ishibashi (2019) using historical documents written in the same period. According to Ishibashi (2019), the length of the source fault was estimated to have been less than 100 km and the earthquake magnitude was roughly estimated to have been around 7.5. In order to attempt to reproduce the interpretation, we conducted two different strong ground motion simulations: the attenuation equation method and the characterized source model method, both used in the Headquarters for Earthquake Research Promotion. We simulated earthquake ground motions based on several source fault models including estimation by Ishibashi (2019). For the length of the fault, a 100 km length corresponding to the Iyonada segment of the Median Tectonic Line active fault system was the first model and 130 km and 160 km models extending onshore to the northeast were taken into account as epistemic uncertainties. Regarding the dip angle of the fault, both 40 and 90 degree models were considered also as epistemic uncertainties. Our calculation with other uncertainties shows that the models with a fault length of 100 km with a dip angle of 90 or 40 degrees are consistent with the seismic intensity and seismogenic fault length of offshore fault estimated by Ishibashi (2019) based on reliable first-grade documents. If low-certainty intensity estimates by Ishibashi (2019) are used to evaluate fault length in our calculation, the possibility of 130 or 160 km length models with additional onshore faults will remain. Our results show that the strong ground motion simulation could reinforce the expert’s interpretation of historical documents and propose quantitative source fault models for historical earthquakes. |

| Title Alternative | New Agglomeration Indicators in Urban and Regional Economies |
| FullText URL | oer_055_1_035_054.pdf |
| Author | Nakamura, Ryohei| Nagamune, Takeshi| |
| Abstract | The indicators of agglomeration in urban and regional economies can be broadly classified into specialization and diversity, each of which is called the Marshal-Arrow-Romer type and the Jacobs type as external economic effects. There is also a Porter-type competitive environment indicator that advocates cluster-like agglomeration. The（modified）specialization coefficient, the Hirshman-Halfindahl index, and the entropy index are examples of indices that directly measure these factors. This paper reviews and evaluates indicators related to urban and regional economic agglomeration developed by Nakamura（2008）and Nakamura（2009）, as well as indicators directly and indirectly related to agglomeration that have been developed since then. rice field. |

| Title Alternative | Onset time and location of the main rupture of the 2018 Hokkaido Eastern Iburi, Japan, earthquake |
| FullText URL | esr_029_049_063.pdf |

| Abstract | The rupture process at the beginning stage of the 2018 Hokkaido Eastern Iburi, Japan, earthquake (MJ 6.7) is investigated by analyzing P-wave records from local strong-motion stations. The records show about 3 s of small amplitude arrival (so-called "initial rupture phase") followed by the onset of the main energy release ("main rupture phase"). In this paper we address the issue: where the seismic energy release corresponding to the main rupture phase started at the primary stage of the main rupture, by locating the main rupture onset position. For this aim we applied the 2D and the 3D search methods to estimate the relative location of the onset of the main rupture with respect to the hypocenter, and the time difference between them. The 2D method assumes a plausible initial fault plane and locates the main rupture onset position on the initial fault plane, while the 3D method does not require such assumed fault planes. In the 2D method we employed each of the nodal planes of the first-motion focal mechanism as the initial rupture plane. The 3D method was able to give a better solution than the 2D one. It suggests that the main rupture initiation point might not be on the same fault plane as the hypocenter is. The solution shows that the main rupture onset point is 5.8 km southward and 2.5 km upward from the hypocenter, with the rupture time of 3.3 s from the origin time. It is consistent with the previous studies on the relationship between the magnitude and the initial rupture duration. |
